At 1 Time Waterproofing, we specialise in waterproofing systems that protect structures from moisture before it causes damage. Our process begins with assessing the surface and selecting the correct membrane for its exposure and substrate type. We use high-performance liquid membranes that form a seamless barrier beneath tiles, slabs and coatings, preventing water ingress while allowing for movement and temperature variation. This ensures compliance with Australian Standards and long-term protection against leaks and mould.

We complete internal and external waterproofing for bathrooms, balconies, decks and basements, as well as large-scale commercial or industrial applications. Each system is installed by trained professionals who follow strict preparation and curing processes. The result is a watertight finish designed to safeguard your property and avoid costly repairs in the future.

Rising damp occurs when groundwater travels upward through porous materials, leading to staining, salt damage and structural weakening. At 1 Time Waterproofing, we prevent this with high-performance barriers that isolate masonry and foundations from moisture. We apply liquid membranes to internal or external walls to form a continuous seal, protecting against capillary water movement and deterioration.

Concrete repairs are performed where needed to restore strength to affected surfaces and joint sealing eliminates points of entry for moisture. Each system is compliant with Australian Standards and applied to suit the structure’s materials and conditions. Rising damp prevention not only stops visible damage but also helps maintain a dry, stable environment and the longevity of surrounding finishes.

A leaking shower can cause unseen damage to nearby walls and floors. At 1 Time Waterproofing, we identify and repair leaks at their source using compliant products and methods. Our process includes removing deteriorated grout, replacing failed sealant and reinstating waterproof membranes where necessary. We use industry-approved materials that create a watertight seal capable of withstanding constant moisture and use.

Our approach eliminates the need for unnecessary demolition, restoring the area efficiently while maintaining compliance with Australian Standards. By addressing the underlying waterproofing failure, our repairs stop water from spreading and protect structural surfaces from decay. Each shower leak repair is completed with attention to detail, ensuring durability and a clean, long-lasting finish.

Balcony leaks are common in exposed structures where constant weather and movement cause joints and membranes to fail. At 1 Time Waterproofing, we restore balcony integrity by locating and repairing every point of water entry. We reseal expansion joints, reinstate membranes and complete concrete repairs where water has compromised the slab. Our technicians use certified systems that maintain flexibility and adhesion under changing conditions.

We also ensure correct drainage and perimeter sealing to prevent future water pooling or ingress. Every repair is completed to Australian Standards, protecting the surface against further exposure. With our balcony leak repairs, your structure remains watertight, safe and built to last—even under the demanding coastal climate of Tweed Heads.
