Retaining wall waterproofing membrane

Internal Wet Area Waterproofing

Be it Residential, Marine Side, Landscaping, Driveways or Swimming Pools, external retaining wall plays both aesthetic and protective roles. They add beauty to gardens, perimeters and pool surrounds, at the same time they effectively work to keep soil erosion at bay. Retaining walls help eliminate negative impacts on surrounding environment, but this can prove only a temporary solution if the walls are not waterproofed. Please consider the points below;

1.       Before you start the task of waterproofing a retaining wall, make sure you have adequate waterproofing products including the primer, joint sealant, membrane and just as importantly, adequate membrane protection such as Drainage Sheet or Protection Board.

2.       If the wall is precast concrete, the substrate will likely be dry when you come to waterproofing (unless it is rained on prior to waterproofing), if it’s concrete block-it will require core-filling into the blocks prior to waterproofing which will dampen the wall. Be sure to select the most appropriate damp/dry surface primer.

3.       Ensure the substrate is clean, free of dust, sharp edges from concrete core-fill, voids, dust oils and any other contaminants.

4.       The wall should now be ready for the primer coat to be applied, which is followed by the sealant, multiple coats of the waterproofing membranes and adequate membrane protection. Follow the manufacturer’s instructions before using it directly for specifications regarding the application, required thickness, curing times etc.
