Joint Detailing Waterproofing Perth
Waterproofing Performance Depends on the Joints
Movement joints, construction joints and changes in material are common failure points because they must remain watertight while accommodating movement and construction tolerances.
Waterseal details joints as part of the complete membrane system, selecting compatible sealants, bands, waterstops and proprietary joint assemblies.
Correct geometry, preparation, adhesion and termination are essential to long-term performance.
Our silicone and mastic jointing article explains where sealants fit within a complete waterproofing detail.

Joint Detailing 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.
