Core project elements
The service, broken down simply.
Final scope depends on the material, site conditions, and proposal, but these are the central parts of the work. None of the listed systems or supporting services is automatically included in every job.
01Select the complete system
Name the compatible liner, sheet, liquid or board system, drain and accessories for the actual exposure. Combining parts is appropriate only when the combination is expressly supported. Waterproof individual products do not prove that their connections work together.
02Prepare support and drainage
Confirm suitable supporting surfaces and the required slopes before applying the barrier. A membrane does not create drainage geometry. Board support, fasteners and surface preparation must match the chosen method.
03Complete the barrier
Install the specified wet-area coverage with the required seams, overlaps or bands. Liquid systems need their specified film thickness, coats, reinforcement and curing; waterproof board still needs its joints and fasteners detailed.
04Detail openings and horizontal surfaces
Connect corners, changes of plane, pipes, valves, niches, benches, curbs and other penetrations. Horizontal surfaces require their intended drainage and barrier details; decorative trim cannot provide these functions.
05Integrate the drain
Treat the drain connection and barrier as one assembly. A traditional liner method has its own slope, drain and weep-path details; do not casually combine it with a different surface-membrane arrangement.
06Inspect and test before covering
Complete specified inspection and water testing after required curing and before concealment, following the system and applicable local requirements. Record the system and photograph important details. Test duration and return-to-work timing depend on the assembly.
