Capture oil, gas and other hydrocarbons while allowing clean rainwater to flow through. The Filter Pad can be used on construction sites, oil fields and other areas where spill containment is needed but shelters or structures are not available. The polyethylene and PVC design is lightweight but durable - folds for quick and easy storage or transport. The replaceable lining is made of X-Tex material that quickly captures oil, grease and fuel leaks and spills. The two-inch, foam sidewalls of the Filter Pad provide structure and help contain stormwater during periods of quick or large amount of rainfall.
