High-Strength Protection of Geomembrane Liners. As a protective cover for geomembranes for closure caps and stormwater ponds, the GEOWEB system prevents liner damage and degradation. With infill confined in the GEOWEB system, slopes can be designed steeper while maintaining strength and integrity, even when subjected to settlement - common in landfills. The landfill cover system can be designed as a vegetated, aggregate armored, or concrete solution that remains flexible. GEOWEB liner protection is a ‘complete solution’ including integral tendons and ATRA tendon load transfer clips.

Enhanced anaerobic biodegradation is the practice of adding hydrogen (an electron donor) to groundwater and/or soil to increase the number and vitality of indigenous microorganisms performing anaerobic bioremediation (reductive dechlorination) on any anaerobically degradable compound or chlorinated contaminant. The most commonly targeted chlorinated groundwater contaminants are primarily used in industry as degreasing agents and include: Perchloroethylene (PCE), Trichloroethylene (TCE), Dichloroethylene (DCE), Vinyl Chloride (VC).
Other anaerobically degradable compounds include: carbon tetrachloride, chloroform, methylene chloride, certain pesticides/herbicides, perchlorate, nitrate, nitroaromatic explosives (TNT, RDX), dyes and chlorofluorocarbons (CFC’s).
