Remediation Materials

Proven Technologies for Containment and Treatment of Contamination

AquaBlok, Ltd. provides a range of patented products to address many common remediation challenges. All our products utilize a composite particle technology that consists of a coated core (typically stone aggregate). The particles act as a delivery system to facilitate placement of fine-grained active ingredients through a water column to appropriate target locations. AquaBlok® and AquaGate®+ are two distinctly different composite material solutions that have been applied successfully in the United States and key locations around the globe.

AquaGate+ delivers amendments in a thin coating around an inner core, allowing movement of water through the material for treatment, while limiting the migration of contaminants. Sites where AquaBlok and AquaGate+ materials have been applied have been monitored and studied extensively, including an in-depth evaluation by the U.S. EPA. AquaBlok is a proven technology with nearly 100 full-scale applications performed over the past decade.

Sequestration / Isolation

AquaBlok is a family of low-permeability, thin capping materials that provide isolation of contamination from the surface water to establish a new, clean benthic layer for restoration. These materials can be used as a thin layer cap, for post-dredging residual management, in a funnel & gate approach that is intended to minimize the potential for contaminant breakthrough while directing groundwater or advective flow to a treatment gate, and many more applications.

• Provides a thin layer, low hydraulic conductivity, and an immediate clean layer suitable for habitat restoration

• Provides mechanism for post-cap monitoring

• Implementable in connection with either MNA or Dredge & Cap strategy

• Highly cost-effective alternative and less invasive than dredging

Amendment / Treatment Delivery

AquaGate+ is a family of permeable treatment or adsorptive products that are intended to remove contamination from pore water and/or reduce potential of contaminant breakthrough. These materials can be used in a reactive cap, for in-situ treatment, or in a range of other applications to control contaminant migration.

• Provides uniform delivery of small quantities of a high-value treatment material

• Use of powdered treatment materials = faster treatment

• Creates thicker, more uniform layers of treatment media with less material usage

• Offers ability to mix treatment materials with other granular capping materials (less risk of material separation with a wide range of treatment materials) for uniform placement through a water column

PFAS Remediation

PFAS-contaminated groundwater can be addressed in-situ using AquaGate+RemBind as a Permeable Reactive Barrier (PRB). For subaqueous sediments, the same product can be applied directly through a water column to limit the migration of PFAS from pore water, thereby limiting impacts on the benthic community, fish, and other sensitive biological receptors.

Wetland Restoration

SubmerSeed® is a versatile, cost-effective alternative to promote the establishment of beneficial vegetative growth in and around wetland and aquatic systems.

Traditionally, wetland vegetation is introduced (or re-introduced) into an aquatic environment using two basic methods: plug planting or seeding. The SubmerSeed Composite Seeding Technology was developed by AquaBlok, Ltd. to address the limitations of these established propagation methods.
