At 1 Time Waterproofing, we deliver certified waterproofing systems designed to prevent structural damage caused by moisture. Our process begins with surface preparation, ensuring substrates are clean, dry and ready for proper adhesion. We then apply high-quality liquid membranes that form a seamless, flexible barrier beneath tiles, slabs or coatings. These systems are suited to wet areas, balconies, decks, and below-ground surfaces where waterproofing is critical.

Each product we use complies with Australian Standards, providing durability and long-term resistance against water ingress. We also specialise in both internal and external waterproofing for residential, commercial and industrial environments, tailoring materials to match the project’s exposure level and substrate type. Whether protecting a new build or sealing a renovation, our waterproofing delivers proven results that stand up to our region’s climate and prevent costly repairs in the future.

Rising damp occurs when ground moisture travels upward through brickwork, concrete or render. At 1 Time Waterproofing, we prevent this by isolating the structure from its moisture source using high-performance membranes and sealants. Our team applies liquid-applied barriers to internal and external wall surfaces, forming a continuous layer that blocks capillary movement and halts deterioration before it spreads. We also repair damaged concrete and sealing joints where moisture has already compromised integrity.

Proper surface preparation and correct membrane selection are essential—we assess each property to identify the cause and apply a system suited to its foundation materials. Rising damp protection not only stops visible signs like bubbling paint or salt deposits but also safeguards structural strength and air quality. Through compliant installation and durable products, we ensure lasting protection for walls and foundations.

At 1 Time Waterproofing, we repair leaking showers by addressing the root cause of water entry, not just the visible signs. Our technicians identify where moisture has breached—often through failed membranes, cracked grout or deteriorated silicone. We remove damaged materials, reinstate the waterproofing layer and apply new sealants or epoxy grout to create a watertight finish. This process restores the protective barrier without unnecessary demolition, ensuring compliance with Australian Standards.

Our repair systems are designed to withstand everyday use and the constant exposure of wet environments. By resealing properly and using proven waterproofing products, we eliminate the risk of hidden moisture damage, mould and subfloor deterioration. Our approach ensures your shower areas are watertight and compliant.

Balconies are among the most exposed parts of a structure, and once water finds its way beneath the surface, damage can occur quickly. At 1 Time Waterproofing, we restore waterproof protection through professional balcony leak repairs that address both surface and structural concerns. We inspect the membrane, joints and tile finishes to locate failures, then reseal or reinstate layers using certified waterproofing systems. Cracks and expansion joints are repaired with durable sealants, while concrete repairs restore strength and prevent future water ingress.

Every repair is completed to Australian Standards, ensuring the surface remains watertight and capable of withstanding movement and weather exposure. Our process improves drainage, seals perimeters and stops leaks before they spread into living areas below. Whether it’s a tiled, concrete or coated balcony, our repairs deliver a durable, long-term solution that protects against moisture and structural deterioration.
