OR RPE® series of geomembranes
| Oil Resistant Reinforced Polyethylene (OR RPE®) is our standard material for short term soil remediation use. |
| |
 OR RPE® is a variation of the basic RPE® materials with enhanced chemical and oil resistance. OR RPE® is our most commonly used short term soil remediation lining material. It is a light weight, high strength, low cost geomembrane material that is easily fabricated into large sizes with the extended chemical resistance required for soil remediation applications.
OR RPE® is different from our standard RPE® materials in that the coating is a chemically resistant HDPE material. This coating is more resistant to the hydrocarbons found at most soil remediation sites.
OR RPE® is typically used as a site liner for short to medium term soil remediation applications. For clean up of hydrocarbon contaminated sites, or for sites that contained PCB’s, PAH’s, heavy metals, or creosote, OR RPE® is an excellent soil remediation lining choice.
OR RPE® can also be used as a cover material in aggressive environments where chemical resistance is important. OR RPE® is UV stabilized and can be used as an exposed cover for between 3 to 5 years (depending on location and use). |

Each and every liner panel we produce is a custom panel. The way we set up our shop is unique in that our shop welders produce prefabricated panels to best match your containment area. We size each panel to fit, without waste, in a logical sequence in your containment area. In containments with irregular shapes we size our panels to best accommodate the irregular size.
There are no theoretical limits to the size of the liner panels that we can prefabricate but there are some practical limits, notably panel weight. Panel weight is important because of the limits of handling equipment that will be available in the field. OR RPE® is normally limited to a maximum panel weight of 2,500 lbs (1,200 kg); however, if a skilled installation crew is available then a panel of up to 4,000 lbs (1,800 kg) is possible.
Panels are accordion folded in one direction and then rolled in the other direction. Unfolding instructions and dimensions are marked on the individual liner panel. Each panel is wrapped in an opaque, weather resistant covering suitable for shipment and storage.
All shop fabricated seams are 100% visually inspected by the welding operator. Every panel is tested for Film Tear Bond and destructively tested in peel and shear. Quality control reports are available with each panel produced.
For projects larger than a single panel size, we will fabricate multiple panels that are then assembled in the field using tape seams. |
