OILFIELD - Secondary Containment

ENVIRO-GUARD INTERLOCKING TANK BASES

Save money and protect your assets with Interlocking Tank Bases. In the past, preparing a site for above ground storage tank placement included pea gravel installation. While this method appeared more cost effective, over time the gravel was inevitably exposed to leaks and spills. Now costly remediation can be eliminated with Enviro-Guard Foam Interlocking Tank Bases (patent pending). Installed on minimally prepared ground, they not only ease site preparation and reduce setup costs, but their non-permeable surface is easily cleaned for future use.
