In order to get the most out of the roof gardens, a proper root barrier membrane must be installed on the roof. This is imperative to stop root penetration into the building which would compromise the building structural integrity. The REXE Bituplast Garden Membrane, also known as anti-root APP Membrane, is specially designed to resist root penetration on flat roofs that have roof gardens. This is made possible through special additives to the APP waterproofing bitumen substrate, giving the membrane the excellent ability to resist root puncture while still maintaining all its waterproofing qualities.
The Modified APP Membrane has excellent resistance to root penetration thus it is referred to as the anti-root APP waterproofing membrane. It has a special chemical composition that ensures it is environmentally safe and will not harm plants. The membrane has a thermal resistance under a wide range of temperature fluctuation meaning they can be used in extreme weather conditions. They are also resistant to mold, weathering and corrosion thus have a long life span.
The Anti-root APP Waterproofing membrane’s double function of waterproofing and resistance to plant roots makes it suitable for use on buildings with roof gardens, on planters, on subways, and for greening underground building roofs. The Anti-root membrane ensures that plant roots do not damage the structure under plants.
