Recommended sealant: Sika Sikasil Pool or an approved equivalent suitable for swimming pools and the relevant exposure conditions.
-
Inspect the underlying substrate and existing waterproofing membrane for cracks, debonding, deterioration, or failure.
-
Where waterproofing defects are identified, remove the affected finishes as necessary, prepare the substrate, and reinstate a compatible waterproofing system in accordance with the approved specification and manufacturer's recommendations.
-
Conduct the required waterproofing and controlled water tests and ensure all repaired areas are watertight before returning the pool to service.
2. Pool-Related Plumbing Rectification
-
Inspect all swimming pool plumbing systems, associated pipework, fittings, valves, connections, and drainage lines to identify the source of leakage.
-
Carry out appropriate leak detection and testing to determine the condition of the existing plumbing installation.
-
Repair or replace defective pipes, fittings, valves, unions, joints, and connections as required following site inspection.

-
Supply and install a compatible protection board to prevent damage to the waterproofing membrane during backfilling.
-
Supply and install a suitable drainage layer and filter geotextile fabric to facilitate drainage and prevent soil particles from blocking the drainage system.
-
Inspect and verify the planter drainage outlets before reinstating the planter.
-
Conduct the specified waterproofing integrity test and obtain consultant approval before backfilling.
-
Reinstate the removed soil, vegetation, and finishes after successful testing and approval.
4. Investigation and Rectification of Water Accumulation Beneath the Pool Deck

Recommended drainage materials: GF Piping Systems or Wavin compatible drainage products, subject to the existing system and site requirements.
-
Provide or improve drainage provisions to prevent recurring water accumulation within the concealed void.
-
Ensure the proposed drainage arrangement has an appropriate discharge point and does not cause additional water ingress or damage to adjacent structures.
-
Remove residual debris and ensure the affected concealed area is clean and free from standing water upon completion.
5. Waterproofing and Structural Inspection
