AquaBlok - Composite Particle System
AquaBlok is a patented, composite-aggregate technology resembling small stones that is typically comprised of a dense aggregate core. In this application of the technology, a powdered high-swell sodium bentonite coating is utilized (Figure 1) with varying percentages of additive (bentonite) layer by percent of total ...

AquaBlok For Sediment Remediaton - Sediment Capping and In-Situ Treatment
Two products are offered to assist engineers with the design of the most protective but cost-effective sediment remediation materials. AquaBlok is a low-permeability cap to provide physical and chemical isolation of residual sediment contaminants. AquaGate is a permeable in-situ treatment approach that allows for delivery of adsorptive or chemsorptive treatment/active material through the water in a uniform and cost-effective manner.

AquaBlok - Model 3070FW - For Low Permeability Capping
AquaBlok® is a natural clay-based material that can be placed through a water column to achieve thin, low permeability capping layers (i.e. hydraulic conductivity of 5x10-8 cm/sec or better), while providing a habitat suitable for benthic recovery. It has been used on hundreds of full-scale sites in the U.S. and has been successfully evaluated by the USEPA under it"s Superfund Innovative Technology Evaluation ...

AquaGate+PAC - (Activated Carbon) For Active Capping or In-Situ Treatment
AquaGate+PAC provides a means to place powder activated carbon (PAC) through the water to a contaminated sediment surface. This can be done with the material blended with other granular capping materials (i.e. sand) to achieve a uniform distribution within an 'Active Cap', or it can be placed alone in very thin layers to achieve a low impact, in-situ treatment to reduce the bio-availability of contaminants within the ...
-
AquaGate+Organoclay - (Organoclay) For Active Capping or Permeable Treatment Barriers
AquaGate+Organoclay provides a means to place powdered organoclay through the water or within a permeable barrier system. The material can be handled and placed in bulk either alone or in combination with other granular materials (i.e. sand) to achieve uniform distribution of the adsorptive material. Organoclays are generally accepted as a means to mitigate the movement of a wide range of hydrocarbon-based contaminants. It has been used successfully at ...

PONDSEAL - Bentonite-based Sealing Solutions
Many waterways, independent of size and function, are constructed in porous or permeable soils that are not adequately compacted or amended during construction to reliably hold water. Even when soil basins or synthetic "liners" are properly prepared from the onset, a variety of environmental factors (e.g. repeated freeze/thaw cycles, prolonged desiccation, pockets of more permeable soils, animal damage, and even subtle seismic activity) can compromise ...

Geotechnical Applications
The unique physical attributes of AquaBlok – both in its dry and in its hydrated state – have made it a highly versatile material for an equally diverse array of geotechnical applications. The base product’s composition is simple: powdered bentonite wrapped around a stone core. But this unique combination of raw ingredients and all its variations – e.g. particle size, various percentages of clay and stone, and even inclusion of treatment additives – allow for use in many settings and for many distinct purposes.

Cut-Off Walls
The traditional liquid slurry trench method is well known for creating hydraulic barriers and has been used for decades to stem the flow of subsurface water and water-borne contamination. In many cases, a backfill material with more structural strength is desired, particularly where subsurface flow rates are high or in earthen dams or dikes where loads must be ...
-
Anti-Seep Collars/Plugs
Traditionally, “anti-seep collars” made of a variety of materials (rubber, PVC, plastics, etc.) have been recommended and installed as impermeable diaphragms that encircle the pipe. While these structures are intended and often do prevent wash-out, uniform compaction of the soil around the collar can be difficult or impossible, depending on soil characteristics. An installer often has to choose either to minimize compaction, so as not to ...
-
Trench Dams
With typical formulations ranging in size from ¼” to ¾” (in diameter), AquaBlok looks, feels, and handles – at least before it gets wet, that is – much like any crushed stone that would be used to bed a pipe. The difference lies in AquaBlok’s unique veneer of bentonite that wraps each individual stone. Working together, the stone and the clay offer a pourable fill that “self-compacts” when exposed ...

Sediment Remediation
Sediment Remediation remains foundational for the company. Products range from the original AquaBlok® sealant materials (for isolation capping) to a broad range of treatment-oriented formulations – which are sold under the trade name AquaGate™. AquaBlok, Ltd. works closely with engineers, designers, contractors, government and academic researchers, and other stakeholders on a project-specific basis to ensure that materials are custom-formulated to meet unique site-specific demands. A primary goal of the AquaBlok technology in these environmental applications is to reduce the risk-of-remedy often presented by conventional sediment dredging approaches and to promote more viable and sustainable approaches that include in-situ reduction of toxicity.

AquaGate+ - In-Situ Treatment and Active Capping of Contaminated Sediments
AquaGate+ enables cost-effective in-situ treatment and Active Capping of contaminated sediments. Our materials improve remediation outcomes and are shown to reduce the cost of delivering amendment materials in aquatic settings. ...

AquaBlok - Composite- Aggregate Technology
AquaBlok is a patented, composite- aggregate technology resembling small stones and typically comprised of a dense aggregate core, clay or clay-sized materials, and polymers. For typical freshwater product formulations, AquaBlok’s clay (sealant) component consists largely of Bentonite clay. However, other clay minerals or clay- sized materials can be incorporated to meet project-specific needs, including product use in saline environments. Other ...
