Abrégé français

Revêtement flottant prévu pour une masse d'eau. Linvention comporte un substrat souple et imperméable doté dune face inférieure et dune face supérieure opposée à la face inférieure. Le substrat est fixé latéralement sur la surface du plan d'eau, mais peut tout de même se déplacer verticalement lorsque le niveau de l'eau change. Un flotteur est fixé sur la face inférieure du substrat et une structure est fixée de façon rigide au-dessus du flotteur. La structure s'étend au-dessus de la face supérieure du substrat. Le substrat est scellé entre le flotteur et la structure. La force de flottement du flotteur agit contre le poids de la structure, pour maintenir le substrat immédiatement adjacent au flotteur au-dessus de la surface supérieure du plan d'eau, afin de ne pas entraver le drainage des précipitations.


Abrégé anglais

A floating cover for a body of water has a flexible, impermeable substrate with a bottom face and a top face opposite the bottom face. The substrate is secured laterally across the surface of the body of water while being permitted to move vertically as the level of the body of water changes. A float is affixed to the bottom face of the substrate and a structure is rigidly mounted above the float. The structure extends above the top face of the substrate. The substrate is sealed between the float and the structure. The buoyant force of the float acts against the weight of the structure to maintain the substrate immediately adjacent to the float above the top surface of the body of water so as not to interfere with precipitation drainage.
