Sheet membrane
Record polymer or bituminous construction, nominal thickness, roll width and length, lap details and expected exposure. Quote total rolls and usable area separately.

Waterproofing membrane manufacturer sourcing
Define the membrane system before comparing factory quotes. We are an independent sourcing partner helping contractors, importers and developers turn sheet or liquid membrane requirements into a comparable purchase brief.
Request Factory QuotesTwo checks before price
Keep the thickness basis visible
A nominal sheet thickness, a carrier-film thickness and a liquid coating dry-film thickness describe different things. Request the exact product datasheet, units and tolerance, rather than assuming two similarly named membranes perform alike.
For a liquid system, ask the supplier to state coverage assumptions and the specified dry film. Do not convert pail volume directly into guaranteed installed area without the offered formulation and substrate conditions.
Price the complete detail
Primers, tapes, reinforcement, termination bars and protection layers may be separate lines. Mark each inclusion so a lower membrane-only price is not mistaken for a lower installed-system cost.
Sample review can check handling and interfaces, while project acceptance still depends on the exact proposed assembly and the responsible designer.
Start with the material form
Liquid-applied membrane
Describe the substrate, project area, dry-film requirement and details needing reinforcement. Ask which primer, cure conditions and packaging units belong in the proposal.
