The anti-root APP modified bitumen waterproof membrane is an APP (Atactic Polypropylene or Amorphous Polyolefin (APAO, APO)) type modified bitumen membrane, It is reinforced with composite polyester felt and copper foil (Cu), finished with PE film on both sides. It has high resistance to root puncture and excellent mechanical characteristics and dimensional stability. The membranes are widely used at civil and industrial projects where it is necessary to prevent the aggression of plant growth which may damage waterproofing layer.
☆ Superior impermeability, flexibility, and elasticity
☆ Excellent elongation and tension properties
☆ Excellent waterproofing, high temperature, ageing, and anti-root resistance; Will not decay
☆ Strong shape adaptability to deformation and cracks, withstand thermal shocks
☆ Pollution free, no toxic, resistance to chemical attacks, no influence on plants growth
