Waterproofing

At The Tiler, we provide expert waterproofing services tailored for homeowners, builders, and property developers across Nowra, the Shoalhaven, and the broader NSW South Coast. With over 27 years of hands-on experience, our licensed and certified waterproofing technicians understand how critical it is to get the job done right the first time. We specialise in preventing water damage through the use of advanced techniques, attention to detail, and premium materials.

We work exclusively with trusted industry brands such as Sika, Ardex, Tremco, ATA, Davco, and Laticrete to ensure long-lasting, high-performance waterproofing. Our work is fully compliant with Australian Standards AS 3740, which governs waterproofing in wet areas of residential buildings, and AS 4654, which applies to external above-ground waterproofing membranes. Whether you’re waterproofing a bathroom, balcony, rooftop, veranda, or planter box, we follow best-practice methods to deliver reliable results.

Our comprehensive process begins with moisture testing using digital moisture metres to confirm substrate readiness. We then carry out detailed surface preparation and apply Sika sealants and specialised bandage systems to all critical joints, corners, and junctions. Once the surface is sealed and primed, we apply the appropriate waterproofing membrane—chosen from leading brands to suit the specific demands of each project. To ensure the integrity of the waterproofing system, we conduct thorough flood testing and provide full ITP (Inspection Test Plan) documentation, giving our clients confidence and peace of mind that their project meets all compliance and durability standards.
