ARA Building Services’ waterproofing specialists provide remedial solutions to protect your property from water damage.  

All roofing, bathrooms, wet areas and many walls need to be waterproofed to stop moisture from seeping into the interior of a building. For each project, ARA Building Services team of experts take into account the location of the building, as well as its construction and primary use to recommend the best membrane covering. 

The selection of the correct type of membrane is vital for each project and there is no one membrane that fits all requirements. Whichever membrane is used, the membrane coating is only as good as the substrate to which it is applied and the person applying it. 

ARA Building Services’ team has the required knowledge to assess the usage, exposure, the substrate and stability before recommending a specific product. We purchase the most suitable products from long established and proven manufacturers and always apply their products strictly to the manufacturers specifications. 

We provide two main forms of floor and wall membranes and flat roof membranes:

1. Sheet membranes
Sheet membranes are supplied in manageable sizes and are overlapped and bonded by gluing or heat welding them together. Sheet membranes are excellent for high traffic areas and have good long term qualities.

2. Liquid membranes
Liquid membranes form a fully bonded and continuously seam free layer with no joins. These membranes are easily applied, flexible and can be UV resistant. Maintenance and repair for this type of membrane is relatively easy. It also has the ability to breath and is cost effective.
