The document describes PRS Neoweb technology for stabilizing energy production sites. Neoweb is a 3D cellular soil confinement system that stabilizes soil, protects infrastructure from environmental hazards, and reinforces soil to reduce construction costs and timelines. It has been used successfully on numerous oil and gas pipeline and infrastructure projects across remote and challenging terrain. Neoweb provides long-term stabilization and protection of pipelines, roads, and facilities to support efficient and sustainable energy production.
