Waterproofing Membrane OEM Manufacturer in China
1 resources tagged with "Waterproofing"
China supplies two main building waterproofing membrane families: bituminous SBS/APP modified-bitumen sheet (torch-applied, for roofs and foundations) and TPO single-ply (mechanically fixed or adhered). For EU sale these carry CE marking under EN 13967 (membranes against ground moisture/water) and EN 13969 (damp-proofing), and the factory should hold those harmonized-standard test reports. OEM minimums typically start around 1,000 m². The recurring quality issue is thin or inconsistent membrane gauge and weak seams that pass a spot check but fail at the lap joints in service.
Waterproofing membranes are roll goods (bitumen or TPO) that seal roofs, basements, and foundations. The sourcing pitfall is buying on price-per-roll without checking actual thickness and reinforcement — under-gauge membrane and poor lap-weld strength are where leaks start, so verify EN 13967/13969 reports and measure the gauge.

FAQ
SBS, APP, or TPO — which membrane do I need?
SBS modified bitumen stays flexible in cold climates; APP handles heat better; TPO is a single-ply membrane that's lighter and weldable. Choose by climate, substrate, and application method — torch-on bitumen vs mechanically fixed TPO.
What certification is needed to sell waterproofing membrane in the EU?
CE marking under the relevant harmonized standard — EN 13967 for tanking against water, EN 13969 for damp-proofing. Require the factory's current test report tied to the product you're buying.
What is the MOQ for OEM waterproofing membrane?
Orders commonly start around 1,000 m². Custom thickness, reinforcement, or branded print on the roll can raise the minimum and add a small tooling/setup charge.
