WEEP SCREED
BACKGROUND OF THE INVENTION
Field of the Invention
[0002] The present subject matter relates to weep screeds that facilitate
the
application of veneer building materials such as stucco, stone, and brick on
external
walls.
Related Art
[0003] In one form of construction, stucco veneer, brick veneer, stone
veneer and
other such external veneer building materials are used as an exterior finished
wall
material for residential and commercial buildings. These materials allow
architects to
provide a variety of different low maintenance designs and wall textures.
[0004] A weep screed is a building device used with veneer building
finishes. It is
used where the veneer material terminates. In one application, the weep screed
is
attached along the base of the exterior wall where the wall meets the top of
the building
foundation, e.g., the weep screed is placed strategically to overlap the joint
between the
exterior framed wall and the foundation. This prevents water, e.g., rain and
sprinkler
water, from entering between the external wall and the foundation. Such
devices are
also used to support the end of the veneer structure and to provide a means
for
moisture to escape from behind the veneer finish.
[0005] Current methods for applying outer veneer finishes use layers of
various
building materials. For example, for a stucco veneer application on a plywood
CA 2997432 2018-03-05
,
sheathing outer wall, a weep screed is attached overlapping the boundary
between the
foundation and the outer wall supported on the foundation. The plywood
sheathing is
then covered with a weather barrier material such as Tyvek , which extends
onto and
terminates in the weep screed. Over the weather barrier is provided a drainage
mat,
such as DriwalITM Rainscreen, which is a permeable mat-like material that
allows water
to drain through it. Over the drainage mat is provided a mesh, such as a wire
lath,
which acts as a support frame for holding the plaster in place, and which
stabilizes the
first coat of wet plaster when initially applied. The first coat of wet
plaster, e.g., the
scratch coat, is applied onto the mesh. The second or brown coat of plaster is
applied
over the first coat of plaster, and the final finish or stucco coat is applied
onto the
second coat to finish the stucco veneer system. The various layers discussed
above
terminate at the weep screed.
[0006] One potential issue with such materials is the possibility
of moisture and
water getting behind the finished wall veneer material. For example, stucco, a
plaster
material, and brick and stone veneer, which use cementuous materials, are
porous and
may absorb water and water vapor into the building layers beneath the exterior
stucco
surface (the term plaster as used herein includes plaster and cementuous like
materials
used in such veneers). Water vapor can also condense behind the exterior
veneer
surface. Furthermore, poor construction techniques, particularly around
windows where
waterproofing may be applied improperly allow rainwater to get behind the
exterior
veneer wall. The water will drain down the inside of the veneer structure
between the
various construction layers, particularly through the drainage mat if used. If
not
collected and removed properly, this water can damage the finished veneer
material.
For example, if water within or along the veneer finish freezes, it can cause
the veneer
to crack and pieces to break off.
[0007] One problem with prior art weep screeds is that they do not
effectively
facilitate drainage of the water from behind the veneer structure. One type of
weep
screed, as shown in U.S. Patent 5,630, 297 to Rutherford, shields the boundary
between the building foundation and the external wall from water, but provides
little
2
CA 2997432 2018-03-05
support for the veneer and little water management for water draining through
a
drainage mat. In some cases, a second device, e.g., a J-bead, is added in
addition to
the weep screed for support and water management, but this requires a second
piece
and added costs associated therewith.
[0008] Other types of weep screeds include a series of small holes through
the
flange on which the veneer layers terminate. See, e.g., U.S. patent 6,385,932
to
Melchiori. The holes, however, are typically located away from the back flange
of the
weep screed such that they sit below the plaster layer of the veneer and not
the
drainage mat layer. Moreover, because of their position and size, these holes
may
become plugged with plaster and not drain water effectively. The water may be
retained behind and or under the veneer, or flow under the lower end of the
veneer
towards the edge of the weep screed. All of this can cause the veneer finish
to crack
and break over time, particularly when the water freezes.
[0009] Accordingly, an improved weep screed and an improved means for
installing
such veneer building finishes would prove beneficial.
SUMMARY OF THE SPECIFICATION
[00010] The present invention provides an improved weep screed for use in wall
veneer applications. In one form, and in broad terms, the present invention
provides a
weep screed that includes an elongate substantially planar back flange having
an
outward side and an opposite inward side, and which back flange further has a
top edge
and a lower edge. Extending outwardly from the outward side of the back flange
spaced from said top edge is an elongate upper flange. An elongate front
flange
extends upwardly from the upper flange and is spaced from the back flange. At
least
one channel is formed between the front flange and the back flange on the
upper
flange. The upper flange has a plurality of apertures through which water can
drain.
The apertures are spaced from one another and positioned adjacent to the back
flange.
Extending outwardly from the back flange below the upper flange is an elongate
bottom
3
CA 2997432 2018-03-05
flange section which has an upper member extending outwardly and downwardly
from
the back flange and further includes an outer edge spaced from the back
flange.
[00011] In one embodiment, the apertures are positioned in the weep screed to
be
directly below the drainage mat to allow water to drain from the drainage mat
and out
the weep screed without passing under the lower edge of the plaster.
[00012] In another embedment, the upper flange is divided into at least two
sections,
one for the weather barrier and drainage mat, the other for the mesh and
plaster. This
helps keep the water from the drainage mat away from the plaster.
[00013] Another embodiment of the present invention is directed to a method of
applying a veneer finish using the improved weep screed.

DETAILED DESCRIPTION
[00026] With initial reference to Figs. 1 through 6, a weep screed 10 in
accordance
with a preferred embodiment of the present invention is now described. This
embodiment is preferred for stucco veneer applications although it is useable
for other
veneer exterior finish applications as well.
[00027] The weep screed 10 forms generally an elongate construction article
that has
a vertical height H and extends longitudinally a horizontal length L of any
desired
lengths as preferred in the construction industry (see Fig. 2). Regardless of
its initial
length L, the weep screed 10 can be cut to the desired length L for the
particular
application. For orientation purposes in describing the illustrated
embodiments, and
without limiting the invention, the term "inward" means a direction facing or
extending
CA 2997432 2018-03-05
towards the building wall to which the weep screed 10 is attached (leftward in
Figs. 1, 6
and 7); the term "outward" means a direction opposite of "inward" or facing or
extending
away from the building wall to which the weep screed 10 is attached (rightward
in Figs.
1, 6 and 7). The term "upward" means a direction facing or extending upwards
in Figs.
1, 6 and 7; the term "downward" means a direction opposite of "upward" or
facing or
extending downward in Figs. 1, 6 and 7. The terms "horizontal" and "vertical"
have their
ordinary and customary meaning, e.g., the term "horizontal" means extending in
the
same direction as the length L in Fig. 2, and "vertical" means at right angles
to the
horizontal, which includes the direction of the height H.
[00028] Returning to Figs. 1 through 6, the weep screed 10 includes an
elongate
substantially planar vertical back flange 12, which has an outward facing side
14 and an
opposite inward facing side 16 (Fig. 3). The back flange 12 has atop edge 18,
which in
the illustrated embodiment, also defines the top edge of the weep screed 10.
The back
flange further has a lower edge 20, which in the illustrated embodiment, does
not define
the bottom edge of the weep screed 10. A nail line 22 may be provided as a
guide for
the application of nails or other attachment means, and can be provided in any
suitable
form, including a score formed in the material of the back flange 12 as shown,
or by
print.
[00029] Extending outwardly from the outward side 14 of the back flange 12 at
a
substantially right angle thereto is an elongate upper flange 24. The upper
flange has
an upper side 26 and an opposite lower side 28. As seen, the upper flange 14
is
attached to and extends outwardly from the back flange 12 at a position spaced
from
the top edge 18 to provide sufficient height to receive the various building
materials
which terminate at or above the upper flange (see Figs. 6 and 7).
[00030] An elongate front flange 30 extends upwardly from the upper flange 24
at a
substantially right angle thereto spaced from the back flange. In the
illustrated
embodiment, the front flange 30 extends from the outward edge 24a of the upper
flange
24, forming a sideways J-like structure as shown. As seen, the upper flange 24
forms a
6
CA 2997432 2018-03-05
channel 32 between the back flange 12 and front flange 30. The width of the
channel
W1 (Fig. 3), i.e., the distance from the back flange 12 to the front flange
30, is chosen
for receiving the various construction layers therewithin as further described
below and
can be sized for the specific use. The front flange 30 defines a substantially
flat and
vertical outward facing side 30a and further has an upper edge 30b which, in
the
illustrated embodiment, includes a lip 34 extending a short distance inwardly
as shown.
[00031] A plurality of apertures 38 are provided in the upper flange 24
through which
water can drain. The apertures 38 are preferably spaced from one another and
disposed adjacent the back flange 12, preferably immediately adjacent to the
back
flange, i.e., directly along the back flange, or very close thereto. As
discussed below, it
is preferable to locate the apertures 38 directly below the drainage mat used
in the
veneer system to allow water draining through the drainage mat to drain and
exit the
apertures 38. The apertures 38 can take any suitable form and size, including
round
and elongated openings, and in one preferable form, are rectangular shaped
openings
disposed immediately adjacent the back flange 12 as shown.
[00032] It is believed that the placement and configuration of the apertures
38 is
important for ensuring proper water drainage and management. The apertures 38
should be located to cooperate with the drainage mat that will terminate and
sit within
the upper flange 24 of the weep screed 10 through which the water drains from
the
veneer system. Thus, the apertures 38 should preferably be positioned to be
directly
below the drainage mat, and of a suitable size and configuration to handle
satisfactorily
the water without plugging due to dirt and other potential obstacles. In prior
art weep
screeds, apertures, when provided, tend to be small round holes located so as
not to be
below the drainage mat, but in many cases are positioned below the plaster
layers,
thereby interfering with the water drainage. The rectangular configuration
shown for the
plurality of apertures 38 in Fig. 1, about 1 inch length by 3/16 inch width,
spaced from
one another by about 3 inches from center to center of each aperture, and each
located
immediately adjacent the back flange 12 or otherwise to be directly below the
drainage
mat, is a currently preferred configuration for current veneer systems as
further
7
CA 2997432 2018-03-05
described below. Round apertures of about 3/8 inches diameter spaced about 2
inches
apart diameter to diameter positioned immediately adjacent the back flange 12,
or
otherwise to be directly below the rain screen is also believed suitable,
although other
configurations and distances between openings can be used. With current
construction,
the spacing of the apertures 38 from the back flange 12 to the closest edge of
the
apertures 38 is preferably no greater than about 1/4 inch (about 1/4 inch or
less), and in
another form no greater than about 3/16 inch (about 3/16 inch or less), and in
yet
another form no greater than about 1/16 inch (about 1/16 inch or less), all
ranges
including down to 0 inches.
[00033] With continued specific reference to Figs. 1 and 6, along the lower
portion of
the weep screed 10 is an elongate bottom flange section 40 extending outwardly
from
the back flange 12 below the upper flange 24. The bottom flange section 40 has
an
upper elongate member 42 extending outwardly and downwardly from the back
flange
12 as shown and further includes an outer edge 44 spaced from the back flange
12. In
this illustrated embodiment, the upper flange 24 extends from the back flange
12
spaced a distance S above the lower edge 20 of the back flange 12, and the
bottom
flange section 40 extends outwardly from a position along the back flange 12
spaced
below from where the upper flange 24 extends from the back flange 12, here
extending
from the lower edge 20. It is appreciated that this spacing S, from where the
upper
flange 24 and back flange section 40 extend from the back flange 12, depending
on the
configuration, can range from no space (0 inches) between the two to a fairly
large
space, the space S being about 3/8 inches in the illustrated embodiment. The
upper
member 42 is preferably angled downward, forming an obtuse angle relative to
the back
flange 12 greater than about 91 degrees, more preferably any angle within a
range of
about 92 to 110 degrees, even more preferably between about 92 to 105 degrees,
and
more preferably about 100 degrees as used in the illustrated embodiment.
[00034] In the illustrated embodiment, the bottom flange section 40 further
includes a
lower elongate member 46 extending inwardly and downwardly from the upper
member
42 from a location spaced outwardly from the back flange 12, preferably at an
acute
8
CA 2997432 2018-03-05
angle with respect to the upper member 42 so as to form a cavity 48 between
the two.
A bottom elongate lip 50 extending downwardly from the lower member 46 defines
an
edge 52, which also defines the bottom edge 54 of the weep screed 10. The edge
52 of
the lip 50 is preferably coplanar with the back flange 12, (see Fig. 6) so
that both can
abut a wall and foundation that are coplanar. Different configurations are
possible for
different building configurations. The lower member 40 can further include
apertures
56, see Fig. 5, to help bind the weep screed 10 to the plaster at the
beginning of
another veneer wall finish provided below the weep screed 10 as may be
provided in
some building constructions. The apertures 56 shown are about 1/8 inch
diameter and
about 8 inches apart from one another, although other configurations can be
used.
[00035] The weep screed 10 can be made of any suitable materials, including
polymers and plastics such as vinyl and PVC, and metals such as steel, and can
be
formed preferably as a unitary member by extrusion. In the illustrated
embodiment of
Figure 1, the height H is about 4-1/2 inches and the length L is any desired
length. The
back flange 12 height H1 from top 18 to lower edge 20 is about 3-7/8 inches
(see Fig.
2). The upper flange width W1 is about 1 inch (from the outward side of the
back flange
12 to the outward side 30a of the front flange 30) and extends at a right
angle from the
back flange 12 from a distance H2 (see Fig. 1) from the top edge 18 of the
back flange
12 of about 3-1/2 inches. The front flange 30 height H3 (to the top edge 34)
(see Fig. 2)
is about 3/16 inches; and the lip 36 of the top edge 34 has a width W2 (see
Fig. 3)
about 1/16 inches extending inward. The upper member 42 of the bottom flange
section 40 extends downwardly at an angle of about 100 degrees relative to the
back
flange 12. The upper member 42 and lower member 46 of the bottom flange
section 40
are both about 1 inch in width W3 and W4 respectively. The angle between the
upper
member 42 and lower member 46 of the bottom flange section 40 is roughly about
25
degrees, and the lip 50 has a height H4 (see Fig. 2) of about 3/16 inches. The
thickness of the various flanges and sections is about 1/16 inches. The weep
screed 10
can be made in strips of predetermined lengths, and can be cut to the length
needed at
the construction site.
9
CA 2997432 2018-03-05
[00036] With further reference to Figs. 6 and 7, a preferred application of a
stucco
veneer external finish to a building using the weep screed 10 described above
is now
illustrated and described. Fig. 6 shows a cross sectional view of the
completed stucco
veneer system and Fig. 7 shows the various layers peeled back from one another
for
illustration purposes.
[00037] The building has a concrete foundation wall 60 supporting an external
wall 62
having framing members 64, such as metal or wooden studs, and sheathing 66,
such as
plywood, attached thereto. An adhesive flashing tape 70 is applied preferably
over the
boundary 68 between the foundation 60 and the wall 62 to seal out water. The
weep
screed 10 is next applied to the outward side of the sheathing 66 over the
tape 70 so as
to extend over the boundary 68 as shown with the bottom flange section 40
positioned
preferably below the boundary 68 to ensure that water draining from the weep
screed
does so below the boundary 68. The weep screed 10 can be attached/secured to
the sheathing 66 with any suitable attachment means such as nails 72 through
the
weep screed 10 into the sheathing 66 and/or studs 64 as known in the art. An
adhesive
sealing tape 74 is applied preferably over the nails 72 and extends over the
top edge 18
of the weep screed 10 as shown to prevent water from passing through the holes
created in the weep screed by the nails 72.
[00038] Next, at least one layer of a weather barrier 74, such as Tyvek
fabric, is
secured to the outward side of the building wall and extends downward onto the
outward face of the back flange 12, terminating at the upper flange 24. The
weather
barrier is typically about 1/16 inch thick.
[00039] Secured to the building wall on the outward side of the weather
barrier 74 and
terminating at the upper flange 24 is a drainage mat 76, such as Driwall
Rainscreen, a
porous material through which water can pass. In the illustrated embodiment,
the
drainage mat is about 1/4 inches thick. The weep screed 10 of the illustrated
embodiment is configured for use with a drainage mat of about 1/4 inches
thick, having
an upper flange width W1 of about 1 inch. Where thinner or thicker drainage
mats are
CA 2997432 2018-03-05
used, it may be preferable to use a weep screed configured accordingly, e.g.,
upper
flange width W1 ranges between about 5/8 inch to 1 1/4 inch. For example, for
drainage
mats 76 greater than 1/4 inch up to about 10 mm, which is just over 3/8 inch,
a weep
screed having a upper flange width W1 of about 1 1/4 inches may be preferable.
[00040] Next, secured to the building wall 62 on the outward of the drainage
mat 76
and terminating at the upper flange 24 is a layer of mesh material 78 capable
of
supporting the plaster in place and which stabilizes the first coat of wet
plaster. Such
mesh materials 78 can include metal lath and metal wire lath and any other
suitable
materials for such use as known in the art. The mesh material 78 is secured in
place by
any suitable means, such as staples 80 which pass into the sheathing 66 as
shown
(Fig. 6), and which also secures in place the weather barrier 74 and drainage
mat 76. In
the illustrated embodiment, the mesh material 78 is formed of metal lath about
1/8 inch
thick.
[00041] A first layer of plaster 82, called a scratch coat, next is applied
onto the mesh
material 78, and embedded into the mesh material 78 as shown, forming a layer
of
about 3/8 inches thick. The first layer terminates at the upper flange 24.
This is
followed by a second coat of plaster 84 of about 3/8 inches thick called a
brown coat. A
thin final finish coat of stucco plaster 86 of about 1/8 inches is applied
onto the second
coat 84 and terminates preferably over the outer face 30a of the front flange
30,
incorporating the front flange 30 to provide a nice looking finish, although
the outer face
30a can be left exposed if desired.
[00042] As seen in Fig. 6, the apertures 38 are located directly below the
drainage
mat 76. Any water and moisture that penetrate the plaster can drain or vent
down
through the drainage mat 76 and out from the upper flange 24 through the
apertures 38,
as illustrated by arrow 88, onto the outer surface 89 of the upper member 42
of the
bottom flange section 40. Once on the outer surface 89, the water is directed
away
from the building and away from the foundation 60 or any lower veneer
finishes. This is
contrary to prior art weep screeds in which the water may be maintained
underneath the
11
CA 2997432 2018-03-05
various layers, including the plaster layers, or flow outwardly along the
bottom edge of
the plaster to drain over an outer edge of the weep screed. Thus, the weep
screed 10
of the present invention allows the water to drain from behind the plaster
layers,
avoiding the cracking and damage problems caused by prior art weep screeds. As
another advantage, ensuring that the apertures 38 are directly below the
drainage mat
76 and not blocked by some of the other veneer system materials allows airflow
into
and venting of the drainage mat 76. This helps to keep the drainage mat 76 and
space
behind the veneer finish dry.
[00043] A second embodiment of the present invention is now described with
reference to Figs. 8 and 9. The weep screed 100 is similar to the weep screed
10
described above, and similar elements are designated with the same reference
numbers. The main difference here is the upper flange configuration that will
be
described in more detail below.
[00044] Similar to the above described weep screed, the weep screed 100
includes
an elongate substantially planar vertical back flange 12 having an outward
facing side
14, an opposite inward facing side 16, and a top edge 18, which defines the
top edge of
the weep screed 100. The back flange further has a lower edge 20 and a scored
nail
line 22.
[00045] Along the lower portion of the weep screed 100 is the elongate bottom
flange
section 40 extending outwardly from the back flange 12 below the upper flange
24. The
bottom flange section 40 includes an upper elongate member 42 extending
outwardly
and downwardly from the back flange 12 as shown and further includes an outer
edge
44 spaced from the back flange 12 and the upper flange 24. The upper member 42
is
preferably angled downward, forming an obtuse angle relative to the back
flange 12 as
described above with reference to the weep screed 10. The bottom flange
section 40
further includes the lower elongate member 46 extending inwardly and
downwardly from
the upper member 42 from a location spaced outwardly from the back flange 12.
The
lower elongate member 46 extends downwardly preferably at an acute angle with
12
CA 2997432 2018-03-05
respect to the upper member 42, forming a cavity 48 between the two with a
distance of
about 3/8 inches between the two along the inward side 16 of the weep screed.
A
bottom elongate lip 50 extending downwardly from the lower member 46 defines
an
edge 52, which also defines the bottom edge 54 of the weep screed 100. Again,
the
edge 52 of the lip 50 is preferably coplanar with the back flange 12 so that
both can
abut a wall 62 and foundation 60 that are coplanar. The lower member 46 also
includes
openings 56 in the lower member 46 for attaching to a stucco veneer below.
[00046] Returning to the upper flange 24, here, the upper flange 24 includes
an inner
flange section 90 and an outer flange section 92 separated from one another by
a
divider wall 94. The inner flange section 90 extends outwardly from the
outward side 14
of the back flange 12 at a substantially right angle thereto and includes a
plurality of
apertures 38. The outer flange section 92 extends outwardly from the divider
wall 94 at
a substantially right angle relative to the back flange 12. An elongate front
flange 30
extends upwardly from the outer flange section 92 at a substantially right
angle thereto
spaced from the back flange, and here extending from the edge 24a forming a
sideways
J-like structure as shown. The front flange 30 defines a substantially flat
and vertical
outward facing side 30a and further has an upper edge 30b, which includes a
lip 34
extending a short distance inwardly as shown.
[00047] In this illustrated embodiment, the inner and outer flange sections
90, 92 are
at different heights relative to one another as shown, here the outer flange
section 92
being at a lower elevation than the inner flange section 90. The divider wall
94 has a
lower section 96 extending downwardly from the inner flange section 90 from
which the
outer flange section 92 extends. The divider wall 94 further includes an upper
extending section 98 extending above the inner and outer flange sections 90,
92. It is
seen that the upper flange 24 forms two channels 32a, 32b between the back
flange 12
and front flange 30, here separated by the divider wall 94.
[00048] The weep screed 100 is used similarly with veneer systems as discussed
above with reference to Figs. 6 and 7, the main difference being that the
weather barrier
13
CA 2997432 2018-03-05
74 and drainage mat 76 terminate in the channel 32a and the mesh 78 and
plaster/stucco coats 82, 84, 88 terminate in the channel 32b. This provides a
separate
channel 32a which collects and drains the water through apertures 38, keeping
the
water in the channel 32a away from the terminal ends of the plaster coats 82,
84, 88.
As an example where the finish is a veneer stone, the weather barrier 74 and
drainage
mat 76 terminate in the channel 32a, and the matrix 78, scratch coat 82 and
stone
veneer layer terminate in the channel 32b. Similarly, as with the weep screed
10
discussed above, the widths of the channels 32a, 32b can be chosen for the
particular
use. For example, channel 32 would have a preferred width of 1/4 inch for use
with a
drainage mat 76 of 1/4 inch. For a thicker drainage mat 76, a wider channel
32a is
preferred as discussed above. Likewise, the thickness of the channel 32b can
be
chosen for the particular use, i.e., thickness of the veneers terminating
therein, e.g.
brick versus stone versus stucco. As an example, preferable widths for channel
32b
can range from 1/2 inch (e.g. stone veneer) to 7/8 inch.
[00049] A third embodiment of the present invention is now described with
reference
to Figs. 10 and 11. A weep screed 110 is illustrated similar to the weep
screed 100
described above, and similar elements are designated with the same reference
numbers. The main difference here is the elongate bottom flange section 40
extending
outwardly from the back flange 12 below the upper flange 24. The bottom flange
section 40 includes the upper elongate member 42 extending outwardly and
downwardly from the back flange 12 as shown and further includes an outer edge
44
spaced from the back flange 12. The upper member 42 is preferably angled
downward,
forming an obtuse angle relative to the back flange 12 as described above with
reference to the weep screed 10. However, unlike the weep screeds discussed
above,
the upper member 42 extends outwardly beyond the upper flange 24 and does not
include a lower elongate member 46, instead ending with a downwardly extending
lip
112 leading to the weep screed bottom edge 54. This configuration is preferred
where
the foundation 60 extends outwardly beyond the wall 62, see Figs. 6 and 7,
requiring
the additional length for upper member 42 to direct water from the apertures
38 away

from the foundation 60. This embodiment also uses rectangular apertures 38 as
shown
and described for the weep screed 10 above.
[00050] The previous description is provided to enable a person skilled in the
art to
make and use the present subject matter. Various modifications to these
aspects will be
readily apparent to those skilled in the art, and the generic principles
defined herein may
be applied to other aspects without departing from the spirit or scope of the
subject
matter. For example, one or more elements in the different embodiments can be
rearranged and/or combined, or additional elements may be added. Thus, the
present
subject matter is not intended to be limited to the aspects shown herein but
is to be
accorded the widest scope consistent with the principles and novel features
disclosed
herein.
