Anti-root puncture and waterproof membrane focuses on root puncture prevention and functionality. SBS refers to elastomer modified asphalt waterproofing membrane. The key is that the modifier of petroleum bitumen is SBS (styrene-butadiene-styrene).
1.Different concepts:.
Anti-root puncture waterproofing membrane is made by physical anti-root (such as polymer sheet anti-root membrane and copper foil tire base membrane, etc.) or chemical anti-root (such as adding anti-root SBS modified asphalt waterproofing membrane). This method prevents the roots of the plant from penetrating the waterproof membrane, which not only achieves the effect of waterproofing, but also does not affect the growth of the plant. It is a waterproofing membrane used for planting roofs.
SBS modified asphalt waterproofing membrane is a relatively common waterproofing membrane used in ordinary areas, compared with root puncture resistance. The focus is on the differences in modifiers and the waterproofing effect.
The overlap between the two is the addition of chemical root inhibitors in the production process of SBS modified asphalt waterproofing membrane, or the use of composite copper and other metal bases to convert it into root puncture resistant SBS modified asphalt waterproofing membrane.
2.The waterproofing engineering parts used are different:
Generally, SBS is suitable for the construction of conventional waterproof layer, focusing on waterproof performance. However, anti-root puncture waterproofing membranes can be used for special areas such as planting roofs. It is not only required to have a waterproof effect, but also to have anti-root thorn performance. It will follow higher.
3.The tire base used in rolled steel is different:
The substrate of SBS modified asphalt waterproofing membrane is generally a fiber woven structure, such as polyester felt, glass fiber felt, etc.; The base material of the root-puncture resistant waterproofing membrane is generally metal-based or polymer materials, such as copper foil Taiji, composite copper-based, etc. It is required to have a certain resistance and can be pierced by plant rhizomes.
How to apply anti-root thorn waterproofing membrane.
1.Clean the ground first and make sure it is dry and flat. If there is an uneven problem during the construction process, it needs to be leveled or polished first, and then applied a treatment agent on the ground to allow it to dry completely.
2.Next, it is necessary to add a layer of waterproof layer to the construction surface, and a layer of membrane needs to be added at the yin and yang corners, deformation joints, etc. Next, lay a layer of root-puncture waterproof membrane on the ground and choose the hot melt method. First, mark the wire on the ground, position the coil, and re-roll it up.
3.The spray gun is lit on site to bake the joint between the bottom surface of the coil and the ground, so that the asphalt is melted and heated along the width of the coil. At the same time as heating, roll forward and lay, at the same time, the air inside must be excluded so that the connection between the film and the ground is strong.
4.Next, the seams of the coil need to be edgebanded, and the operation needs to be carried out in the opposite direction of progress. If the sealing is done well, it can bring a good waterproofing effect.
