Lift Pit Waterproofing Perth
Lift Pit Waterproofing Against Groundwater Ingress
Lift pits sit below the surrounding floor level and are vulnerable to groundwater, construction-joint leakage and penetrations through concrete. Even minor seepage can affect equipment, safety and building operations.
Waterseal installs external tanking, internal negative-side systems, waterstops and remedial treatments for new and existing lift pits.
The correct approach depends on access, water pressure, concrete condition and whether the structure can be treated from the positive side.

Lift Pit Waterproofing FAQs
The exact scope depends on the structure and condition. Waterseal reviews substrates, joints, penetrations, drainage, terminations and the compatible membrane or coating system required for the area.
Yes. Waterseal delivers new installations, membrane replacements and targeted remedial waterproofing. Existing conditions are assessed before a repair system is recommended.
Selection considers the substrate, exposure, movement, moisture, access, required finish, construction sequence and compatibility with adjoining materials.
Where practical, scopes can be coordinated in stages around access, cure times, other trades and operational constraints. These requirements should be identified during planning.
Preparation is a critical part of waterproofing. The required grinding, cleaning, repairs, crack treatment and priming are defined according to the substrate and selected system.
Send drawings, photographs, the project location, programme, known leak history and any existing specifications or reports. Waterseal can then advise whether a site inspection is required.
