Waterproof Sheeting
Waterproof Sheeting is high-performance polymer waterproof liner made of high-quality raw materials, mainly used for waterproofing, anti-seepage and moisture isolation in tunnel, underground engineering, road construction and water conservancy projects.
Introduction
Waterproof Sheeting is a practical geosynthetic waterproof material widely used to block water penetration and prevent underground water seepage. It features stable physical property and strong adaptability, keeping engineering structures dry and safe in harsh construction environments.
What is Waterproof Sheeting?
Waterproof Sheeting is a thick flexible impermeable sheet produced by professional extrusion process. It acts as a reliable waterproof barrier to isolate underground water, rainwater and moisture effectively, protecting building foundations and engineering structures from water erosion and damage.
Types of Waterproof Sheeting
Smooth Waterproof Sheeting: flat surface, easy construction
Textured Waterproof Sheeting: anti-slip surface, firm laying
EVA Waterproof Sheeting: soft texture, good ductility
HDPE Waterproof Sheeting: high strength, long service life
