"Dingtong" polyester tire chemical root blocking and root puncture resistance Waterproof roll It is APP modified with long fiber polyester fiber felt, special composite copper substrate or copper foil substrate as coiled material substrate and imported chemical root inhibitor added asphalt For coating material, both sides are covered with polymer ethylene Membrane fine sand Or modified asphalt coiled material made of mineral aggregate as isolation material.
Product Description
"Dingtong" polyester tire chemical root blocking and puncture resistant waterproof coiled material is a modified asphalt coiled material which is made of long fiber polyester fiber felt, special composite copper base or copper foil base as the coiled material base, APP modified asphalt added with imported chemical root blocking agent as the coating material, and polyethylene film, fine sand or mineral particles as the isolation material on both sides.
Product Features
1. It has dual functions of waterproof and preventing the penetration of plant roots, can withstand the penetration of plant roots, and can maintain waterproof function for a long time. It can prevent root penetration without affecting the normal growth of plants.
2. It can form a high waterproof layer, with strong resistance to pressure water, puncture resistance, crack resistance, tear resistance and fatigue resistance.
3. High tensile strength, large thickness of modified asphalt coating, and strong adaptability to base shrinkage deformation and cracking.
4. Good high and low temperature resistance, applicable to both cold and hot areas, with good corrosion resistance, mold resistance and weather resistance.
5. Hot melt construction, convenient construction and reliable and durable hot joints.
[Main purpose]
It is applicable to the plant root puncture resistant layer of the planting roof and the roof of underground buildings that need greening, to ensure that the plant root does not damage the structure below this layer, and has waterproof function.
[System structure level and key points]
The planting system is generally composed of vegetation layer, planting soil, filter aquifer, drainage layer, protective layer, ARC polymer modified asphalt root puncture resistant waterproof layer, ordinary APP modified asphalt waterproof layer, leveling layer, insulation layer, slope making layer, structural plate and other layers:
Structural slab: it must be cast-in-place reinforced concrete. When the roof slope is greater than 15%, anti-skid measures shall be taken for waterproof layer, drainage layer and planting soil layer. When the roof slope is greater than 50%, it is not suitable for planting.
Slope making layer: the roof slope shall be 2%. Available when the slope length is within 4m cement Mortar slope making; When the slope length is 4~9m, aerated concrete, lightweight ceramsite concrete, expanded perlite cement mortar or vermiculite cement mortar can be used as slope materials; When the slope length is more than 9m, the structure shall be used for slope making.
Thermal insulation layer: polystyrene foam plastic board, polyethylene foam plastic board and on-site spraying hard foaming polyurethane should be selected as the thermal insulation layer. If the thickness of planting soil is more than 800mm, the thermal insulation layer may not be set. In the area south of the Yangtze River, the thermal insulation layer may also be omitted.
Leveling layer: 1:2.5 cement mortar can be used to lay a cement mortar leveling layer with a thickness of 20mm~25mm. The leveling layer shall be provided with division joints with a spacing of no more than 6m.
Ordinary APP modified asphalt waterproof layer: 4mm or 5mm APP modified asphalt waterproof coiled material should be used for a waterproof treatment. Hot melt construction.
Dingtong polymer modified asphalt root puncture resistant waterproof layer: 4mm or 5mm ARC modified asphalt root puncture resistant waterproof coiled material is selected, which has both root resistance and waterproof functions, and is used for hot melt construction.
Protective layer: 200g/m two Polyester non-woven fabric, empty laying method construction, overlapping width 200mm.
Drainage layer: the plastic drainage board with a concave convex height of 8~20mm can be used, and the empty laying method can be used for construction. The overlapping width is not less than 150mm. Light ceramsite or pebble with particle size less than 25mm can also be used as drainage layer, and the laying thickness is 80~100mm. No drainage layer can be set in dry and rainless areas (the total annual precipitation is less than 400mm); When the thickness of planting soil is less than 150mm or more than 1500mm, no drainage layer can be set. The drainage board with water storage function can also be selected, and only one filter layer needs to be set on it.
Filtration and aquifer: density greater than 400g/m can be used two The chemical fiber felt and mineral wool mat of the "" shall be laid on the drainage layer in an empty way, with a lapping width of 100mm, and the joints shall be sewed with thread. When the thickness of planting soil is greater than 500mm, it has sufficient water storage capacity, and it is unnecessary to set up an aquifer, which can be 200g/m two Polyester non-woven fabric is used as filter layer.
Planting soil: improved soil or composite planting soil should be used for roof planting; Pastoral soil should be selected for the planting of basement roof. The thickness of planting soil is determined according to plant species.
