A waterproofing membrane is a layer of water-tight material that is laid onto a surface to prevent water leaks or damage. Waterproofing membranes generally consist of liquid applied or pre-formed sheet membranes. They can be adhered or installed around the foundations (like a structural slab) to prevent water penetration.
Whether waterproofing is required to protect your building’s basement or roof, this modern technology will help stop water from infiltrating your foundation and protect your structure from water damage over the long-term. In addition, our team have used the Araldite injection systems for extensive crack repair, and torch-down roofing. Whatever your company needs, we can customise a solution for you.
When the Wither Hills Winery on the outskirts of Blenheim embarked on creating a spectacular new cellar door and administration building with roof garden; a huge area of tanking was to be done to ensure waterproofing below ground.
The cellar and walls (almost two storeys high) were to be buried under 6,000m3 of backfill soil. Approximately 800m2 of the cellar and 1,000m2 of the first floor needed to be tanked.
As there were two parts to the tanking process requiring two different methods of application, two types of materials were chosen for the tanking. Both materials have a long history within the industry and are proven to provide protection, however the products are quite different, requiring distinctly different applications.
Construction Coating’s tanking made a successful contribution to the finished project. The main contractor we supported in this process picked up a top national accolade by beating four other contending finalists to win the National 2006 Gold Registered Master Builders Award for a Commercial and Business project.
The new stadium for Nelson at Saxton Field was a design and build project for Arrow International. There are some 800m2 of flat roofs and gutters to this building, and the architect selected Allnex Soprema torch-on membranes from France, as the product for this job.
As subcontractor to Arrow International, Construction Coatings Limited installed the two layer system plus fillets, using Soprasun 3 for the base layer and 4AR mineral chip for the top layer. The gutters were finished with Soprasun 3+4 plain, then overcoated with Allnex Cural bituminous aluminium coating.
The whole project took over twelve months, with the waterproofing tradeworks completed by Construction Coatings Limited on time and on budget once again.
