We've just added a fantastic new product to our range - Ardex WPM750 aka Undertile Butynol.
This innovative product is for use in bathrooms prior to tiling.
Undertile butynol is strong - much stronger that traditional liquid applied or 'paint on' systems, has heat welded seams and is fully compatible with most tile adhesives.
Among its many excellent attributes is its fast turnaround time - it can be tiled on only 1 hour after installation and is installed in one visit - no waiting for a second coat!
If you'd like to know more about this or any of our bathroom waterproofing systems, including Newline shower bases, please give us a call!

Nuraply and other single layer bitumen membranes.
We've been receiving more and more 'SOS' emails from people with leaking Nuraply and other Single layer bitumen (torch on) roofs lately, so I thought I'd take a moment to post about them.
For a few years now it's been required by councils that all 'torch on' or bitumen based membranes be double layer systems. This was to bring NZ into line with overseas practice, and also due to a high number of failures of single layer systems.
Unfortunately for many home owners this change came too late, and they are now stuck with an ailing single ply bitumen based roof.
There are a few common issues:
- Break down of membrane due to UV (often seen as crazing, and cracking)
- Loose membrane due to adhesive failure
- Raised or wrinkled sections (often in conjunction with the above symptoms)
- Failing seams
- Failing Gel coats (eg on NURAPLY systems)
NB: If you collect rainwater for drinking off of your roof it is crucial that your gel coat is intact or that the surface is painted - Un-coated bitumen contains carcinogens and is not suitable for potable water!
Very often these issues are present together and exacerbate over time.
The good news is that these issues can be remedied - there are a number of different solutions depending on the nature and severity of any problems. If in doubt, please get in touch - we're always happy to answer your questions and suggest a solution.
