Root blocking copper base is a waterproof coiled material made of polyethylene (PE) film with asphalt as the main material, high elastic styrene-butadiene rubber or low temperature resistant chemical raw materials, composite copper base in the middle and outer layer. This product can play the functions of waterproof and root blocking, filtering sediment, preventing nutrient soil loss, discharging excess water and storing appropriate amount of water for plant growth. It is a multi-functional waterproof membrane integrating waterproof, root blocking, filtering and water storage.

The planting system is generally composed of vegetation layer, planting soil, filter aquifer, drainage layer, protective layer, polymer root-resistant copper matrix, ordinary SBS modified asphalt waterproof layer, leveling layer, protective layer, slope making layer, structural plate, etc. It has the dual functions of waterproof and preventing the penetration of plant roots. It can withstand the penetration of plant roots and maintain the waterproof function for a long time.

It not only prevents root puncture, but also does not affect the normal growth of plants. It has excellent extension and high tear resistance, can form a high-strength waterproof layer, has strong compression resistance, and is resistant to puncture, tear, corrosion and mold. High and low temperature resistance, suitable for cold and hot areas, can be attached with self-adhesive layer to improve the operability of construction.

It is applicable to the basement, roof and roof of all kinds of buildings and the waterproof areas of all kinds of buildings that need waterproof function and are resistant to plant root penetration. The base course must be strictly checked before paving the root blocking copper base, and the base surface must be solid and flat, without bulge, concave-convex or sand; The base course shall be dry and the moisture content shall be controlled within 9% before construction.

The internal and external corners shall be plastered into an arc shape, and additional layers shall be added to the special parts such as the pipe root drain. Lay and position the coiled material, and then use the cold bonding method or the hot melting method to bond the coiled material. The hot melting method has a better bonding effect, which can reduce the cost and ensure that the hollowing phenomenon of the waterproof interlayer can be avoided in the future. Reserve a 10cm wide seam overlap and ignite the blowtorch to evenly heat.

After the surface of the blocked copper base is melted, it shall be paved forward. Pay attention not to get involved in air and foreign matters during rolling. It must be compacted and flattened after exhausting. Before the coil is cooled, the edge shall be sealed with a trowel, and then the edge and its complex parts shall be sealed to prevent warping.
