REACTIVE CORE MAT™ (RCM) is a permeable composite mat consisting of reactive material(s) encapsulated between non-woven polypropylene textiles. Through its innovative processing, RCM can combine two active materials, if required. RCM is available with a variety of active materials including ORGANOCLAY®, Apatite, and Granular Activated Carbon.

BENTOBLOCK™ is natural sodium bentonite screened to 3/8 inch (0.95 cm) to 3/4 inch (1.90 cm) in size. It is designed to be mixed with aggregate and placed in sub-aqueous low-permeability sediment caps.




Product INformation



Remediation of contaminated sediment can be one of the most challenging environmental concerns. Contaminated sediment sites are often large and complex. Due to concerns over contaminant re-suspension, dewatering and final disposal, dredging may only be considered as only a component of the remedy. In-situ treatment and capping of contaminated sediment offers many benefits.

Vadose Remediation Technologies can assist you in the design of active sediment cap and modeling the anticipated cap design life.

  • In-situ sediment treatment and capping with permeable Reactive Core Mat®
  • Sediment treatment and capping with permeable and impermeable bulk materials
  • Shoreline seepage control using mats and bulk materials
  • Adsorptive layer prevents contaminant transport into surface waters
  • Active treatment reduces requirements for cap thickness
  • High value active materials are evenly distributed with a mat, to ensure verifiable coverage
  • Durable polypropylene geotextiles provide geotechnical stability

sediment capping

and treatment

ORGANOCLAY is a proprietary filtration and adsorption media capable of adsorbing oil, grease, NAPL and dissolved low-soluble organic compounds. It may be used in a mat form (RCM) or applied in bulk sediment capping applications.
