Preparing a waterproofing and roof-system enquiry
A useful enquiry defines the water-control detail and the surrounding build-up. Separate product dimensions from the required performance and installation scope.

Selection considerations
Provide the location, substrate, joint geometry and movement requirement where relevant. Identify roof membrane or wet-area system interfaces and describe expected exposure. Include drawings of corners, terminations and outlets.
Request the proposed BULDX codes with compatible adhesives, connection pieces and preparation materials. Ask for performance documentation specific to the application rather than a broad claim of waterproofness. Compare complete systems, including inspection and installation responsibilities, so omitted bonding or connection components do not distort the price comparison.
Before you specify or order
- Include surrounding build-up drawings
- Request compatible bonding components
- Make performance requirements explicit

Common question
What often gets missed in a waterproofing quote?
Terminations, corners, compatible adhesives and substrate preparation, especially when only straight lengths are listed.
