Welcome to B & J Whitsed Waterproofing, your local specialists for dependable outdoor waterproofing in Highfields — built to protect homes from heavy rain, humidity, and Queensland’s unpredictable weather. If water is finding its way into patios, decks, balconies, or outdoor living areas, professional outdoor waterproofing is the long-term solution you need.
In Highfields, seasonal downpours, sudden storms, and strong UV exposure can quickly wear down unprotected outdoor surfaces. That’s why our outdoor waterproofing systems are designed specifically for local conditions, helping homeowners in Highfields protect their property and avoid costly damage.
Our outdoor waterproofing services are built for durability, not shortcuts.
We seal bathrooms, showers, toilets, laundries and kitchens to AS 3740 and the NCC. This covers waterproof floors where required, wall and floor junctions, penetrations for mixers and spouts, and risk zones around inset sinks and laundry tubs. We prepare substrates, apply primers, build film thickness to specification, and document cure windows so tiling happens at the right time, not too soon.

Roofs & Decks
Any room at risk of water exposure
We waterproof decks, balconies, roof areas over habitable rooms, garages, sheds, outdoor kitchens and retaining walls. For external above ground assemblies we specify AS 4654 compliant systems with correct falls, drainage, overflow provisions, UV resistance and durable terminations that prevent water tracking behind the membrane. This is essential for the Australian climate’s heat, humidity and sudden changes, as our outdoor page notes for decks and garages in Toowoomba conditions (Outdoor Waterproofing).

Showers receive fully waterproof floors and walls to a compliant height with sealed junctions, graded membranes to wastes and water stops at thresholds. Penetrations at mixers and outlets are detailed to stay watertight behind tiles so the whole bathroom performs for the long term.
Laundry floors, skirtings, tub surrounds and washing machine tap zones are sealed to the correct resistance level for the substrate, with wastes and junctions treated so spills and hose bursts cannot wick into framing or cabinetry.
External membranes are matched to UV exposure and traffic, with falls to drains, overflow paths and precise terminations at door sills, balustrades and parapets. The system resists ponding, thermal movement and driven rain to keep interiors dry.
From kitchens with inset sinks to powder rooms and plant rooms, we target localised moisture barriers at benchtop junctions, service penetrations and wall areas around vessels in line with NCC Part 10.2, preventing hidden ingress where failures often start.
Authoritative guidance on the above can be reviewed here: NCC Part 10.2, HIA on AS 3740, AS 4654 overview.
Every outdoor waterproofing job in Highfields starts with a detailed inspection. We assess drainage, surface condition, and exposure risks before selecting the right waterproofing membranes and coatings. This ensures your outdoor waterproofing solution performs reliably through wet seasons and dry spells alike.

Outdoor waterproofing in Highfields isn’t just a finishing touch — it’s critical protection. With regular rainfall and moisture exposure, outdoor areas like patios, decks, and balconies are at risk of leaks, mould growth, timber rot, and concrete deterioration. Proper outdoor waterproofing helps prevent water ingress while extending the lifespan of your outdoor spaces in Highfields.
Once applied and cured, outdoor waterproofing forms a protective barrier that immediately helps prevent water penetration.
Decks, patios, balconies, terraces, retaining walls, and exposed external walls all benefit from outdoor waterproofing in Highfields.
