AquaBlok® is a composite-aggregate technology resembling small stones that consists of a dense aggregate core, clay or clay-sized materials, and polymers. AquaBlok’s line of low-permeability, thin capping solutions is ideal for sealing, containment and sediment remediation. When hydrated, AquaBlok particles expand and self-compact to create a low-permeability seal without mechanical compaction. The hydrated AquaBlok acts as an effective barrier for water and chemicals.
