GP-PPM-R High Molecular Polyethylene Polypropylene Root Puncture Resistant Waterproof Membrane
High molecular polyethylene polypropylene root puncture resistant waterproof membrane is a root puncture resistant special waterproof membrane made of modified synthetic high molecular resin waterproof core layer as the main root barrier waterproof layer,high-strength filament fiber fabric as the reinforcement layer. using a composite process made of special waterproofing roll-roofing resistant to root puncture. With the matching root-blocking binder, forming a solid, reliable, root-puncture resistant polyethylene polypropylene root-puncture resistant waterproofing system.

(Other colors can be customized according to customer needs).
Product Features
●It has the function of preventing plant root penetration and can withstand plant root puncture;
●Both anti-root puncture without affecting the normal growth of plants;
●High mechanical strength and strong puncture resistance;
●Good flexibility, easy to bend, arbitrary folding, easy to operate;
●Good chemical resistance, aging resistance, corrosion resistance;
●The coil supporting root-blocking binder, which itself is a root-puncture resistant layer, forming a double insurance coefficient of root-puncture resistant waterproofing system.
Application Scope
It is suitable for projects such as planted roofs, roof gardens, garage roofs, and roofs of buildings that require greening. Due to its good acid, alkali, and salt resistance, it is more suitable for root-piercing planting systems in coastal areas or projects with corrosion resistance requirements.
