Fibreglass or polyester
A fibreglass carrier is dimensionally stable and costs less; a polyester carrier elongates further and takes more punishment. Specify Orko for static substrates and the TM polyester range where the structure moves or the membrane will be trafficked.
Applications
Water tanks, swimming pools, bathrooms and wet rooms, roofs, car parks and retaining walls.
Laying
Clean the substrate of dust, oil and chemicals and prime with TM MASTIKA bitumen mastic. Torch applied, with side overlaps of at least 10 cm and end overlaps of 15 cm.
Loading and delivery
EXW Ashgabat. Rolls are stacked upright on pallets and stretch-wrapped. The producer exports to Turkey, Russia, Kazakhstan, Uzbekistan, Azerbaijan, Tajikistan, Kyrgyzstan, the UAE, Europe and the USA.
