Service Coverage

INTERNAL BASEMENT WATERPROOFING SOLUTIONS
Our expert basement waterproofing services include crack injection with epoxy or polyurethane to seal leaks, waterproof membranes applied to walls and floors for lasting protection, and rising damp treatments using barriers or chemical damp-proof courses to stop moisture from wicking through masonry. We have the best basement water seepage solutions in Brisbane and Gold Coast.

EXTERNAL BASEMENT WATERPROOFING SOLUTIONS
Excavation & Membrane Installation: Digging around the basement to apply bituminous or polyurethane membranes, along with installing subsoil drains (drainage systems) or agi pipes to redirect groundwater away from the foundation. Protective drainage boards are also installed to shield the membranes and improve water flow.

FLOOR, WALL & FOUNDATION CRACK INJECTION
Cracks in the concrete can be filled with epoxy for structural reinforcement, or with hydrophobic/hydrophilic polyurethane to seal and prevent moisture ingress.

BASEMENT REMEDIATION & LEAK DETECTION
Failed concrete basement waterproofing and drainage systems often need to be repaired or replaced to prevent ongoing moisture issues and structural damage. At the same time, concrete repair and sealing help restore integrity by fixing cracks and resealing porous surfaces—protecting your space from future water intrusion.

SUMP PUMP & BASEMENT DRAINAGE SOLUTIONS
To manage groundwater effectively, SuperiorWaterproofing experts may add internal drainage, perimeter drains, and sump pump systems to collect and expel water.
