Composite particles and methods for their application and implementation
In a method of creating a seal in a subsurface environment, a plurality of manufactured composite particles are placed in the subsurface environment, the composite particles including a sealant material. The sealant material is hydrated to create a cohesive seal. In a method of controlling erosion of a periodically or continuously inundated surface, a plurality of manufactured composite particles are placed around erosion-control objects. The composite particles include a sealant material which is a cohesive, low-permeability material when hydrated. The sealant material physically stabilizes the erosion-control objects on the surface. The invention also relates to compositions and properties of the composite particles.
