Tarp
Tarps are composite waterproofing materials manufactured by laminating on either one or both sides of a light woven polyolefin (polypropylene or polyethylene) fabrics compatible polymer layers. This light but very resistant sheet can be supplied in standard rolls, but most commonly, they are assembled in large sheets (typical size 50x20m) that make them ideal for small hydraulics jobs (small lagoons) or for temporary coverage in landfill applications.
