General Description

AquaBlok® particles expand when hydrated, with the degree of expansion determined largely by the product formulation and salinity of the hydrating water. When a mass of discrete and relatively hard AquaBlok® particles hydrate and coalesce, the mass transforms into a continuous and relatively soft body of material.

Once developed across a targeted placement surface, the hydrated AquaBlok® material can act as an effective physical, hydraulic, and/or chemical environmental barrier by virtue of its:

  • relatively cohesive character;
  • relatively low permeability to water (e.g. typical freshwater [bentonite-based] formulations display saturated hydraulic conductivity values on the order of 10-9 cm/s.);
  • chemically reactive nature, in that the clay and other high surface-area components can effectively sorb, or attenuate, various types of dissolved contaminants.

In addition to acting as an effective environmental barrier, AquaBlok® can also provide substrate for wetland vegetation as well as habitat for macroinvertebrate organisms, particularly when additional organic materials (food) is provided as part of the product formulation.

The AquaBlok® technology can also act as a vector for the targeted delivery of wetland seeds (see SubmerSeed®) as well as chemical reagents to facilitate in situ treatment of environmental contaminants.
