Waterproofing failure in buildings comes at a huge cost and the extent of damage is often extreme.
The safest waterproof system for wet areas in your home is a compliant waterproof membrane encapsulated by tiles in accordance with the NZ Building code.
One of the biggest mistakes people make in both residential and commercial projects is to try and cut corners (time and investment) by not using quality products. Oftentimes in building, it is what cannot be seen that is the most important to get right. It can be very costly to identify the source of water ingress and fix the problem so it is crucial to follow safe practice.
When it comes to bathroom, foyers, laundries, or kitchens, waterproofing is crucial and worth investing in so ensure you get the best advice and if you decide to use a certified waterproofing professional, ensure you are provided with a waterproofing certificate and warranty after work is completed.
It is worth considering also that a waterproofing membrane is really only as good as the substrate that it’s sitting on. Without a good foundation, if the building moves later on, the substrate and linings could move, and the waterproofing membranes will break.
