AquaBlok® is a patented "composite particle technology" that utilizes a central core (typically stone aggregate) to deliver various fine-grained coating materials for a broad range of environmental applications. The particles act as a "delivery system" – placing active ingredients through a water column or to target locations apt to come into contact with water.

AquaBlok® Stockpile

For many sediment-related applications, AquaBlok® use generally involves applying dry masses of the product through water and across the surface of contaminated sediments. In a matter of days, the layer of initially discrete particles transforms into a homogeneous and relatively cohesive and low-permeability cap - or barrier - occurring between contaminated sediments and the overlying water column and its inhabitants (including benthic invertebrate organisms).

AquaBlok® Before and After Hydration

The hydrated thickness of this barrier will depend on a number of factors, including: the product formulation, water depth; water salinity, dry product coverage rate; number of layers, or lifts applied; and physical characteristics of the sediment.
