Supplied product documents
These summaries are attributed to the technical sheets supplied with the website. Confirm the latest revision, availability and project-specific suitability before ordering. They do not establish an Aamtron certification, installer accreditation or warranty.

Specify the exact product
A polyurethane system is a category description, not a complete specification. Provide the substrate, exposure, expected movement, finish and use. Ask Aamtron to confirm whether the requested item is within the available SR or SF range and suitable for the proposed work. Availability, packaging and individual product performance are subject to confirmation.
Check compatibility and application instructions
Request the current technical and safety documents for the proposed product. Confirm preparation, primer, application conditions, coverage or thickness, curing and protection. Do not infer immersion suitability, drinking-water approval or a certification from a general material name.
Review the whole assembly
Include interfaces with drains, joints, repairs and the final finish in the proposed system. A product supplied for one purpose cannot be assumed suitable for another. For a comparison, read PU and bituminous waterproofing and cementitious and liquid systems.
Request a material or installation quotation
State whether the enquiry is for supply or supply with installation, and include drawings or a specification if available. Contact Aamtron; see the material enquiry overview.
Questions before you start
Discuss your waterproofing requirements
Polyurethane waterproofing and PU foam are different enquiries
Polyurethane waterproofing commonly refers to a liquid-applied membrane system. PU foam refers to a foam material used in a different construction build-up. These terms should not be treated as interchangeable. A search for “PU waterproofing” therefore needs clarification before a material or installation method is specified.
Aamtron supplies and installs SR and SF waterproofing systems. The product documents on this page identify the available polyurethane material information. Supply or installation of spray foam, polyurea or an unrelated brand should not be assumed from this page.
What to provide for a PU membrane enquiry
State the substrate, the approximate area and whether the layer will remain exposed or receive a protective finish. Identify existing coatings, active leaks, drainage points and penetrations. The selected product’s technical data sheet should establish the preparation, primer, application limits, thickness and curing requirements.
Ask whether the proposed build-up needs reinforcement, a protective topcoat or other accessories for the intended conditions. Check how corners, joints, upstands and terminations will be treated. A coating that accommodates a defined degree of movement is not a substitute for a correctly designed movement joint.
Compare the system, not just the pack price
When comparing a roof waterproofing quotation, include preparation, removal or retention of existing material, detailing, access and protection. Confirm the proposed inspection and testing sequence. See our PU versus bitumen comparison and quotation cost guide for a practical comparison checklist.
For a tank or another water-contact application, obtain documentary confirmation that the exact product meets the intended use. Do not transfer a claim from another polyurethane product simply because the chemistry has the same broad name. Contact Aamtron with your application and specification before procurement.
