Waterproofing Done Right — Built To Last
Every PrimeSeal project follows a structured approach — from inspection and substrate preparation through to final checks and handover.
01
Site Inspection
We assess the waterproofing issue on site, identify failure points, and advise on the best-fit system for the substrate and exposure conditions.
02
Surface Preparation
Correct substrate preparation is critical. We clean, repair, and prime surfaces before any waterproofing system is applied.
03
System Application
Professional waterproofing application using the specified membrane system, with attention to critical detailing points and transitions.
04
Final Checks & Protection
Post-application inspection and walkthrough to confirm the installation meets standard and the property is protected.
