Retaining Wall Waterproofing Perth
Retaining Wall Waterproofing Starts on the Soil Side
Retaining walls are exposed to persistent ground moisture and may experience water pressure where drainage is inadequate. Once a wall is backfilled, access to the preferred waterproofing side becomes difficult and expensive.
Waterseal installs retaining wall membranes for homes, builders, commercial developments and civil projects, with remedial options assessed for existing structures.
Correct drainage, terminations and protection are essential parts of the complete wall system.

Retaining Wall 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.
