The detail

External Walls, done properly.

Below-grade walls and retaining structures face constant pressure from groundwater, stormwater and landscaping. Once water finds a path through blockwork or concrete, dampness, efflorescence and structural issues follow.

We excavate where required, prepare the substrate and apply durable liquid membranes, sealing around pipes, weep holes and junctions so water cannot undermine the home.

We excavate, prepare and coat external walls and footings with durable liquid membranes, sealing around pipes, weep holes and junctions so groundwater and stormwater cannot undermine your home.

  1. 01

    Excavate & expose

    We carefully expose the wall or footing so the full waterproofing plane can be prepared and coated correctly.

  2. 02

    Clean & prepare

    Surfaces are cleaned, defects addressed and junctions detailed before membrane application.

  3. 03

    Membrane application

    A durable liquid membrane system is applied to the wall and footing, with upturns and pipe penetrations sealed.

  4. 04

    Protect & backfill

    Once cured, the system is protected as needed and the site is reinstated ready for drainage and landscaping.

Common questions

What homeowners ask

Do you waterproof retaining walls?

Yes. Retaining walls, foundation stem walls and below-grade external walls are a core part of our work across Queensland.

Will you dig out around the wall?

Where access requires it, we excavate to expose the waterproofing face, then reinstate after the membrane is complete.

Is this suitable for coastal Sunshine Coast properties?

Yes. Our systems are chosen for Queensland rainfall, humidity and the conditions coastal and hillside sites typically face.
