Cementitious composite mat

A cementitious composite for in-situ hydration, the cementitious composite comprising:

• a membrane including a structure layer and an impermeable layer;
• a containment layer disposed along a first side of the structure layer, wherein the impermeable layer is disposed along an opposing second side of the structure layer;
• and
• a cementitious mixture disposed along and within the membrane, the cementitious mixture including cementitious material, aggregate, and absorbent material, the absorbent material configured to absorb water and at least one of expand and gel during in-situ hydration and thereby lock the cementitious material and aggregate in place to prevent washout of the cementitious mixture from the membrane;
• wherein the containment layer includes a water soluble adhesive coating that includes a curing agent configured to be absorbed by the cementitious mixture during in-situ hydration.

A cementitious composite for in-situ hydration, the cementitious composite comprising:

• a structure layer having at least one strand arranged in at least one of a coiled configuration and a bunched configuration, the structure layer forming a mat having a first side and an opposing second side;
• a cementitious material disposed within the structure layer, the cementitious material including a plurality of cementitious particles;
• a sealing layer disposed along the first side of the structure layer and coupled to the at least one strand;
• and
• a containment layer disposed along the opposing second side of the structure layer, the containment layer configured to prevent the plurality of cementitious particles from migrating out of the structure layers;
• wherein the containment layer includes a water soluble adhesive coating that includes a curing agent configured to be absorbed by the cementitious material during in-situ hydration.
