ecoTUFF TPO

ecoTUFF TPO membrane is a copolymer of polypropylene and ethylene propylene rubber that has been formed into a membrane sheet and reinforced with a heavy duty polyester scrim.

A ‘second generation' single ply product, ecoTUFF marries the advantages of previous generation materials while eliminating their limitations. The result is a roofing membrane that is faster and easier to install yet offers outstanding resistance to weathering, temperature extremes, ultraviolet exposure and a whole wide variety of industrial chemicals.

epiSPAN EPDM

EPDM: The polymer EPDM, ethylene-propylene rubber, is produced through copolymerization of ethylene, propylene and diene monomer, producing a polymer madeup of saturated linear macromolecules with a paraffinic structure.

In addition to the base polymer, EPDM contains reinforcing carbon black fillers, process chemicals, antioxidants and vulcanizing agents. After mixing the ingredients into ahomogenous plastic compound, two layers of the rubber are rolled out in a calendar toform a double sheet. Vulcanization is then carried out. The long rubber molecules in the material are cross-linked through heat and pressure, creating an elastic membrane.

epiSPAN Wide Sheet Advantage
epiSPAN is available in 3 & 6m wide sheets in New Zealand and up to 15m wide ex factory. These wider sheets reduce laps, potential issues relating to lap application and installation time.

rawMAT Bentonite

The rawMAT Pre-hydrated Bentonite system provides high level waterproofing protection to below ground structures in the most demanding situations.

The advantage of our pre-hydrated bentonite system is that the initial bentonite hydration occurs under factory controlled conditions. Unlike the dry bentonite systems, which are prone to shrinkage and cracking, the Rawmat Pre-hydrated bentonite is highly resistant to the effects of water contaminants. These contaminants induce cationic exchange in dry bentonite systems causing them to have a reduced swell, shrink and crack as the clay converts from sodium bentonite to the calcium form.
