What are the construction methods of sbs waterproofing membrane?
There are two construction methods of sbs waterproofing membrane: cold bonding construction method and hot melting construction method. Cold-bonded construction method needs to evenly coat cold priming oil treatment agent at the grass-roots level first, then evenly coat adhesive on it after the grass-roots level is dry, and then put away the waterproof coiled material before paving.
Advantages of sbs waterproofing membrane
1, sbs waterproofing membrane is highly sensitive to temperature and is very suitable for large slope roofs.
2.sbs waterproofing membrane will be thicker and have good puncture resistance, tear resistance and fatigue resistance.
3.sbs waterproofing membrane not only has excellent elastic extensibility and high ability to bear cracks at the base, but also has certain self-healing ability to bridge cracks.
4.sbs waterproofing membrane adopts hot melt lap joint, and the joint seal is very reliable. However, if it is a coil with a thickness less than 3mm, the hot melt method cannot be used for construction.
5.sbs waterproofing membrane still maintains its excellent performance at low temperature, and can still be constructed even in cold climate, which is very suitable for the north.
Matters needing attention in waterproofing membrane construction
1, before waterproofing membrane construction, we must pay attention to the leveling of the base surface, and there can be no sundries on the base surface. If the construction encounters rainy weather, the construction cannot be carried out.
2, waterproof coiled material is not suitable for construction under negative temperature conditions, if it must be constructed under such conditions, then corresponding measures must be taken to ensure that after paving, the waterproof layer will not appear cracks and poor primary adhesion.
Summary: The above is about the construction method of sbs waterproofing membrane and the advantages of sbs waterproofing membrane, hoping to help everyone. For more information, please keep an eye on Qijia. com。
