We provide a wide range of quality waterproofing services to suit a number of projects and requirements. If you need waterproofing in Perth make sure to contact the professional waterproofing team at Waterseal Waterproofing.

Leak (HVELD) Detection

High Voltage Electronic Leak Detection (HVELD) is a method of detecting breaches in waterproofing membranes and coatings.

Car Parks

From renovating of existing surfaces to application of new coatings, Waterseal Waterproofing partner with market leading manufacturers to supply and install waterproof coatings.

Basements and Undercroft

Correct waterproofing to the below grade elements of a building is critical to ensure that the structure maintains its integrity and liveability.

Lift Pits

Even when constructed at floor level, elevator shafts require excavation below ground level which can leave the lift pit vulnerable to ingress if not waterproofed correctly.

I have worked with Leon and the Waterseal team for almost 15 years now. They have always made the process simple, kept with timeframes and ensured we are compliant with the NCC.

I could not recommend Leon and Waterseal any more highly. Leon was recommended to us during a particularly tricky project and for that I will be forever thankful. Waterseal were able to successfully seal up a pool window where others simply failed. Not only are they knowledgeable and experienced but Leon brings an air of positivity and “can do” attitude that is unfortunately rare these days. Nothing was too much trouble and Leon and his team took on a and successfully completed our project when many others would have simply given up and walked away. You cannot go wrong with Waterseal and they will always be our “go to” for our waterproofing and sealing requirements

Leon and the team at Waterseal have been our go to waterproofing specialists for a number of years. We use them across all our jobs, commercial and residential. Leon is extremely knowledgeable about all aspects of Waterproofing and his advice on all our projects is invaluable. In an industry where time matters, Leon always responds to every request in a timely manner and completes every job to an excellent standard. We would recommend Waterseal to anyone.

Exactus Homes Logo
We at Exactus have used Leon and Waterseal for over 10 years to look after our water proofing jobs. I have found Leon and his staff to be both friendly and most importantly reliable to deal with. Leon has a wealth of knowledge in waterproofing and has been an invaluable source of information especially when required. I always tell my clients “in the building industry, if you find a good trades person, stick with them”. Leon is definitely that, Exactus will continue to use Waterseal for the foreseeable future.

Thank you for your incredible support and customer service for our family during an extremely difficult time for us after finding mould and rising damp in our sons room, after I had contacted multiple different companies none could be punctual or give clear guidance and pricing and didn’t seem interested in helping us, however you and your team were friendly, extremely knowledgeable, punctual and very tidy (during a VERY messy job of grinding back the concrete) you left no mess and were happy to stay in touch, checking in with the finished product after you were done, and seeing if there was anything else you could do to help us, the personal touch, understanding and time spent to support my disabled children to feel confutable with having you all in our space was amazing, we have never had such an awesome team of tradesmen. Thankyou from the bottom of my heart for all you did for us, we can not recommend you and the Waterseal team highly enough. 11/10 stars. Thanks guys.

Each project has had several different waterproofing requirements which Leon has had an answer for. Waterseal are organised, polite, on time and provide good solutions to difficult situations. I have no hesitation in recommending their services.
