Waterproofing Membranes

Waterproofing membranes are the barriers that keep water where it belongs — out of buildings, structures, and substrates. In reinforced fabric form, a polyester core carries tensile load while the polymer faces provide the watertight layer, producing membranes that bridge small substrate movements without splitting and weld into continuous, seam-checked systems. That mechanical reinforcement is what separates fabric-backed membranes from plain bituminous or film sheets on demanding details.
Application Families

Foundation and below-grade — tanking and foundation wraps where soil moisture and hydrostatic pressure work for decades.
Roof and terrace — sheet membranes under finishes or as exposed systems, needing UV packages and root resistance where planted.
Wet areas and tanks — internal waterproofing for bathrooms, pools, and water tanks, welded to eliminate joints.
Civil works — bridges, tunnels, and retaining structures where movement accommodation matters most.

What Decides Long-Term Performance
Detailing beats material: corners, penetrations, and terminations are where waterproofing actually fails, so weldability and field workability deserve as much attention as the datasheet numbers. Compatibility with the covering system (adhesives, screeds, finishes) prevents later delamination, and for exposed uses the UV and temperature package must match the climate, not the catalogue average.
Kezhibo manufactures reinforced waterproofing membrane fabrics on knife-coating lines, delivering the thickness uniformity that reliable field welding needs. Custom widths, weights, and polymer packages run through our custom manufacturing services under ISO 9001 certified quality management, with exports serving contractors and distributors across Asia and Europe. Tell us the structure, the water exposure, and the covering system; we will propose a membrane that welds well on your site, not just in our catalogue.
