Abstract
A cementitious composite for in-situ hydration includes a structure layer having a first side and an opposing second side, a cementitious material disposed within the structure layer, a sealing layer disposed along and coupled to the first side of the structure layer, and a containment layer disposed along the opposing second side of the structure layer. The structure layer has an intersection at the sealing layer and the containment layer that is at least partially fiberless. The cementitious material includes a plurality of cementitious particles. The containment layer is configured to prevent the plurality of cementitious particles from migrating out of the structure layer.

A cementitious composite for in-situ hydration, the cementitious composite comprising:
- a structure layer having a first side and an opposing second side;
- a cementitious material disposed within the structure layer;
- a sealing layer disposed along and coupled to the first side of the structure layer;
- and
- a containment layer disposed along the opposing second side of the structure layer, the containment layer configured to prevent the cementitious material from migrating out of the structure layer;
- wherein the containment layer includes a water soluble coating that includes a curing agent configured to be absorbed by the cementitious material during in-situ hydration.
A cementitious composite for in-situ hydration, the cementitious composite comprising:
- an impermeable layer;
- and
- a cementitious mixture disposed along the impermeable layer, the cementitious mixture including a dry cementitious material and interconnection particles;
- wherein the interconnection particles are configured to at least one of melt, fuse, deform, or expand in response to activation to form an interconnecting structure within the dry cementitious material that attaches to the impermeable layer;
- wherein the interconnecting structure serves as a structure layer.
A cementitious composite for in-situ hydration, the cementitious composite comprising:
- a water impermeable layer;
- a water permeable layer;
- a cementitious mixture disposed between the water impermeable layer and the water permeable layer, the cementitious mixture including cementitious material;
- and
- a structure layer extending between the water impermeable layer and the water permeable layer;
- wherein the cementitious mixture comprises a majority of a volume between the water impermeable layer and the water permeable layer.
