The special root puncture-resistant waterproof membrane for planting roofing is based on polyester fiber felt as the tire base. A waterproof membrane with excellent root-blocking properties made of SBS/APP modified asphalt with imported chemical root-blocking agent (or root-blocking copper tire base) as the coating material, and polyethylene film, fine sand or mineral pellets as the isolation material.In addition to its excellent waterproof properties, the product is mixed with special chemical root inhibitors in SBS/APP modified asphalt, which can effectively prevent plant roots from penetrating the waterproof layer, thereby ensuring the service life of the waterproof material.

The products include two varieties of SBS modified asphalt root puncture resistant waterproof membrane and APP modified asphalt root puncture resistant waterproof membrane.The thickness of the coil is 4.0mm, and the product performance includes basic performance and application performance.The basic performance meets the corresponding national standard requirements: SBS modified asphalt root puncture resistant waterproof membrane meets the requirements of GB18242 standard type II product, and APP modified asphalt root puncture resistant waterproof membrane meets the requirements of GB18243 standard type II product.

Product features：

◎ It has the dual functions of waterproof and preventing plant root penetration. It can withstand plant root puncture and maintain waterproof function for a long time. ;

◎ The modified asphalt made of imported chemical root inhibitors is resistant to plant root puncture, does not affect the normal growth of plants, and has no pollution to the environment. ;

◎ It can form a high-strength waterproof layer, has strong resistance to pressure water, and is resistant to puncture, cracking, tearing, and fatigue. ;

◎ High tensile strength, high elongation, strong adaptability to shrinkage, deformation and cracking of the base layer ;

◎ Excellent high and low temperature resistance, suitable for hot and cold areas ;

◎ Corrosion resistance, mold resistance, and good weather resistance ;

◎ Hot melt method construction, convenient construction and reliable and durable hot joints.

Scope of application：

It is mainly suitable for the waterproof and root blocking of the roof of underground buildings for planting roofing and greening.

Construction process：

Grassroots treatment：

◎ The waterproof base layer must be cleaned, kept firm, dry, smooth (smooth), etc.

◎ Where the construction surface is uneven, it should be filled or smoothed first, and the edges and inner corners must also be rounded (rolled) in advance.

◎ Completely apply the base treatment agent to all construction surfaces and wait for it to dry completely.

Additional waterproof layer for node details：

General details such as three-sided yin and yang corners, gutter, gutter, deformation joints, etc., shall be affixed with an additional layer of special coil according to relevant specifications.

Ordinary waterproof layer construction: hot melt construction.

Construction of the root-blocking waterproof layer: hot melt construction, the construction method is the same as the construction method of ordinary modified asphalt waterproof membrane.
