AquaBlok® for Freshwater Settings
This is a bentonite-based sealing material designed for use in freshwater settings. It provides uniform delivery of powdered sodium bentonite directly through a water column, in saturated settings (e.g. below groundwater table), or where mechanical compaction is difficult or not possible. It will provide a low-permeability (hydraulic conductivity of 5x10-8 cm/sec) seal when hydrated. Resembling small stones, a major benefit of AquaBlok 2080FW is ease and speed of handling and installation.
AquaBlok for Marine Settings
A saltwater-compatible formulation of AquaBlok’s bentonite-based sealing material is also available for applications where water with salinity in the range of 12-35ppt will hydrate the product. By including attapulgite clay to the material’s powdered sodium bentonite coating, the material will achieve low-permeability (hydraulic conductivity in the range of 5x10-6 cm/sec) without mechanical compaction. If placed beneath an armor layer or other vertical load, lower long-term permeabilities can be achieved. The SW formulation is not as cohesive as the FW formulation and often requires an armor or erosion protection layer, if exposed to flow or moving water.
Other AquaBlok Products
AquaBlok also provides a range of material formulations to address other applications and settings, such as well sealing, levees and dams, and more. For more information on these products and applications, please contact AquaBlok.
