At Sealantz Auckland, our main priority is to identify and install the waterproofing system most applicable for your project ensuring a watertight structure and peace of mind for years to come.


In the world of waterproofing there are no second chances. The systems installed must be the correct systems for the type of waterproofing required. The ‘leaky building’ era of the last decade is partly due to waterproofing systems being installed in situations they were not designed for.


When you deal with Sealantz Auckland you can be assured of expert advice, punctuality, professional conduct, and workmanship of the highest quality. In fact, our company slogan is “we do it right – the first time” and we strive to ensure that this is the case EVERY time.
