Root Penetration Resistance Roof Membrane

1.introduce

Root  Penetration Resistance Roof Membrane is a kind of macro-molecule material  produced by advanced equipment and technology which uses high quality bitumen  as its main component, Styrene-Butadiene-Styrene(SBS) as its modified  materials, root resistance materials as its reinforcement cores and many  excellent materials such as PE as its insulation materials.

1) Have a double functions of waterproofing and  root penetration resistance;
 2) Not affect the normal growth of plants;
 3) Excellent penetration resistance, wearing  resistance, tearing resistance, corrosion resistance, mould resistance and  weather resistance.
 4) Good tensile strength and elongation; large  thickness of modified bituminous coating, strong adaptability for substrate  shrinkage, deformation and cracks;
 5) Excellent low and high temperature resistance,  it can be adaptive in both hot and cold regions
 6) It uses heat fusion method, which is  convenient, reliable and durable.
 

4.   Application scope

         planted roof                                                   dams

 4.1 Green roofs, balconies of commercial,  industrial and civil buildings ;
 4.2 Underground landscaping demanded building  roofs.
 4.3 Dams need to be protected from the damage by  roots.
 

5.  Executive standard:
 JC/T1075-2008;  Root penetration resistance of waterproof sheets for green roof system.
 JGJ155-2007;  Technical specifications for planted roof.
 GB50108-2008;  Technical code for waterproofing of underground works

6. Construction -  Heat Fusion  Method:
 1)Surfaces  should be dry, clean, smooth and free from any dusts, oil or loose particles.  Cracks and surface irregularities need to be filled by polymer mortar.
 2)Before  membrane laying, brush the primer on basement evenly and completely cover all  laying places.
 3)heat  the membranes evenly, pave the membranes on basement according to the alignment  when the membrane surface is black and bright with a fusion layer and keep the  membrane straight and smooth, ensure the joint area min. 60 mm overlap (length  and width). Press the membranes tightly to make sure the trapped air to be  excluded and the membranes bonded with basement firmly, no bubbles and wrinkles  allowed.
 4)visual  inspection and mechanical inspection(i.e. use a flat head screwdriver to check)  first.
 5)Application  on protection and isolation layer, after membrane laying, construct protection  and isolation layer according to waterproof layer design.
 

7. Cautions
 1) Rainy, snowy or high windy( more than five  level) days are not suitable to construct, and construction temperature should  be above 0℃.
 2) When heating, flame spraying guns should  maintain a proper distance with the membranes and should heat them evenly.  Overheating should be prevented.
 3)Safety precautions are necessary and fire  equipment should be placed properly.8.   Storage and Transportation:
 

8, Storage and Transportation:
 1) Package type: rolling package.
 2) Different types or specifications should be  separated. Keep them dry and ventilated, out of the sun or rain.
 3) Storage temperature should be 5~45℃. Membranes  should be upright with only ONE layer.
 4) Prevent it from inclination or lateral  pressure. If necessary, cover it with felt-cloth.
 5) Storage time: 1 year under normal operation of  storage.
