Bathrooms are common areas for moisture problems. In Alexandria, we offer trusted bathroom waterproofing, installing membranes behind tiles and fittings to stop leaks and protect the structure. Everything we do follows AS 3740 compliance.
Exposed to intense sun and rainfall, balconies demand proper care. Our waterproofing prevents leaks and concrete damage using UV-resistant coatings formulated for Alexandria.
When laundries and kitchens collect moisture, it can lead to mould growth and damage to wood. Our Alexandria waterproofing includes full underfloor and wall sealing to protect cabinetry and subfloor areas.
Leaks often occur in planter boxes that aren’t sealed correctly. We provide planter box waterproofing with root-resistant membranes to prevent water overflow and wall damage.
Waterproofing decorative ponds and pools requires expert solutions. Our service in Alexandria includes the use of flexible coatings made for full-time submersion.
Roof shape doesn’t matter—flat or sloped, it needs defence. Our torch-on membrane systems and drainage methods protect from Alexandria’s stormy seasons.
Precision is essential in shower zones. We use pre-tiling membranes and leak barriers that fully comply with AS/NZS 4858 regulations.
It depends on the area and how much moisture it gets. Bathrooms and similar wet areas call for internal waterproofing, while external systems work better on rooftops and balconies.
