High-Visibility Orange Woven Warning Layer for Ground Protection & Utility Marking

The High Visibility Orange Woven Membrane for Ground Protection & Contamination Control is a practical choice for civil engineering and construction projects where ground separation and clear hazard marking are both required. Made from extruded polypropylene tapes, this woven geomembrane is designed for contaminated ground applications, helping to maintain separation between layers while providing a visible underground warning during future excavation work.

Its bright orange finish offers clear visual identification below ground, while the membrane helps prevent the upward migration of contaminated soil particles and the intermixing of adjacent mineral layers. With resistance to naturally occurring soil acids and alkalis, as well as bacteria and fungi, it is suited to demanding site conditions and offers a predicted lifespan of at least 25 years in typical soil conditions.
