FilterMat^TM is a custom-designed, effective geocomposite for contaiment purposes of contaminated sites.

FilterMat^TM is a geocomposite designed for use in a multitude of geo-environmental applications.  FilterMat^TM incorporates one or more layers of activated carbon between engineered nonwoven fabrics that are designed to provide filtration and puncture protection, resulting in an effective geocomposite for sediment capping applications.  FilterMat^TM is engineered to remove chemical contaminants in water columns and for capping contaminated sediments in rivers and lakes.  Installation of FilterMat^TM in capping applications is completed with placement of a cover layer of sand, stone or rock.

In situations where a warning to future construction operations is desired, BlazeMat^TM is a version of our activated carbon composite which is produced with a bright orange pre-filter nonwoven that acts as an identification layer to protect against disruption of capped sediments.

These composites can be applied in both land and water capping applications using existing industry-standard equipment.

FilterMat^TM is a composite consisting of at least three layers – a nonwoven top and bottom layer surrounding one or more activated carbon layers.  This structure creates a two-step-containment:  the bottom nonwoven layer acts as a puncture protection and pre-filter keeping contaminated particles and gravel in place whereas the activated carbon absorbs dissolved contaminants passing thru the nonwoven structure.  The top nonwoven layer protects the product against puncturing caused by covering material.  Both FilterMat^TM and BlazeMat^TM are manufactured in roll widths of up to 25 feet, reducing installation costs and time.

Typical applications:

• Sediment capping
• Containment curtains
• Geotextiles filter tubes

• Activated carbon
• Nonwovens for puncture protection and filtering
• 100% mechanically bonded geocomposites
• Comtrac^® can be added for high strength characteristics
