Waterproofing
ASAP Waterproofing Specialists deliver comprehensive waterproofing solutions for residential and commercial properties. Our services include liquid membrane systems, PVC sheet membranes, and crack injection to prevent water ingress. We address issues like rising damp, basement leaks, and roof seepage using Australian Standards-compliant products. Our team ensures long-term protection with warranties up to 20 years.
Liquid Membrane Systems
We install high-performance liquid membrane systems tailored to specific project needs. These seamless coatings eliminate joints and overlaps, offering durability in harsh climates. Ideal for flat roofs, balconies, and bathrooms, our Tamsi-based systems provide flexible, solvent-free protection with excellent adhesion to various substrates.
PVC Sheet Membrane
ASAP offers certified PVC and Butynol sheet membrane installations for high-risk areas like roofs and planter boxes. These systems feature 15-30 year warranties and are applied by manufacturer-trained technicians. The membranes resist UV exposure, chemical damage, and mechanical stress for long-term reliability.
Crack Injection
Our crack injection services use low-viscosity acrylic resins to seal concrete cracks and water leaks. This method restores structural integrity while preventing moisture penetration. Ideal for retaining walls, basements, and underground structures, ensuring watertightness with minimal disruption to existing surfaces.
Remedial Waterproofing
We specialise in diagnosing and repairing failed waterproofing systems. Our remedial services include membrane replacement, rising damp treatment, and joint sealing for residential, strata, and commercial clients. We provide free inspections and quotations to address water ingress issues effectively.
