Internal Waterproofing

So, you’re building or renovating and need internal waterproofing. You’ve come to the right place! Our family-owned team of waterproofers are fully licensed and accredited with Ardex membranes, and our combined experience spans decades. We’ve worked on residential and commercial builds and our waterproofing is second to none. Our focus is on quality and service, and providing you with great end result with no issues between various trades is what we strive for with every job.

All works meet the Australian Standard for internal waterproofing across the various domestic, commercial and educational building requirements. We’re more than happy to quote works from building plans (you can click here to contact us and email your PDF plans), but we prefer to give a more personal service. We like to sit down with your project managers or estimators to discuss what you’re hoping to achieve, what you need out of the service, and why we feel we’re a great choice for your project. We can also discuss critical dates and other trades that will need to be worked around. 

The internal waterproofing services we do includes things like:

• Enclosed and unenclosed showers, including wall recesses
• Bath hobs and freestanding baths 
• Bathroom and washroom waterproofing 
• Laundries and other wet areas that include troughs or basins
• Toilet blocks
• Leak detection and waterproofing assessment services

Internal waterproofing pricing for rooms is based on area and perimeter, with shower costs based on the overall size of the shower. All quotations we provide are completely transparent, and are displayed as sq/m and l/m costs, itemised per wet area.
