Abstract
A cementitious composite includes a structure layer, a cementitious material, a water-impermeable sealing layer, and a containment layer. The structure layer has a first side and an opposing second side. The structure layer defines a plurality of open spaces. The cementitious material includes a plurality of cementitious particles disposed within the plurality of open spaces of the structure layer. The water-impermeable sealing layer is disposed along the first side of the structure layer. The containment layer is disposed along the opposing second side of the structure layer. The containment layer is positioned to prevent the plurality of cementitious particles from migrating out of the structure layer through the containment layer.
Claims14
A cementitious composite comprising:
- a structure layer having a first side and an opposing second side, the structure layer defining a plurality of open spaces, wherein the structure layer includes a plurality of fibers arranged in a nonwoven configuration, and wherein the plurality of fibers are arranged to form a plurality of discrete nodes spaced relative to one another such that the plurality of fibers cooperatively define the plurality of open spaces between the plurality of discrete nodes;
- a cementitious material including a plurality of cementitious particles disposed within the plurality of open spaces of the structure layer;
- a water-impermeable sealing layer disposed along the first side of the structure layer;
- and
- a containment layer disposed along the opposing second side of the structure layer, the containment layer positioned to prevent the plurality of cementitious particles from migrating out of the structure layer through the containment layer.
