A repair bladder manufactured to meet the demands of
small pipe rehabilitation.
The said bladder will be flexible as to navigate
through clean-outs as well as 45 degree elbows and
90 degree elbows. The said bladder will still be able
to stay firm enough to be able to be launched through
clean-outs and pushed into place and keep its shape.
The bladder should also be of a flow-through design
as to allow water to pass through. The bladder will
also be made of a material that will not stick to cured
resin. This bladder will also be reusable. The
bladder will be made of gum rubber so as to allow
the bladder to pull away from the repair.
The bladder will consist of two end caps made of
aluminum or other light material. These caps will be
joined by a non-stretching hose which will allow
liquids to pass through. The extruded rubber sleeve is
positioned over these ends and fastened. Air fittings
are attached and harness receiving ends are attached.
