PVC plastic water stop

PVC plastic water stop, also known as "plastic water stop," which is made of PVC polyvinyl chloride resin and various additives filling, sealing material by mixing, granulation, extrusion and other processes and made by mixing , granulation, extrusion processes and products made of water stop. This product is the use of elastomeric material having elastic deformation characteristics play in building construction joints in leak-proof, anti-seepage effect, and corrosion resistant, and good durability.
Plastic water stop leverages elastic deformation properties of PVC resin has played leakproof joints in building construction, the effect of seepage and corrosion resistant, and good durability. We produce plastic water stop specifications: 280 × 6,300 × 4,300 × 6,300 × 8,300 × 10,350 × 8,350 × 10 and so on. PVC plastic water stop mainly used for concrete pouring is disposed within the concrete construction joints and deformation crack constituted as one of the infrastructure projects. Such as tunnels, culverts, water aqueducts, dams, reservoir structures, underground facilities.

PVC plastic water stop construction methods
Plastic water stop rubber water stop with the same construction method. When you want to bury it with pouring concrete interface bonding formation, adhesive fastening joint portion, pouring buried in an appropriate process to force full vibrating concrete to bind concrete good, to get the best sealing effect .
PVC plastic water stop Construction Notes
1. In the construction process, because there are a lot of concrete and steel sharp stones, action is taken to avoid mechanical damage to the water stop.
2. Positioning the plastic water stop when you want to make the concrete bonding interface formation, can not appear water stop flipping, twisting and other phenomena, or should be timely alignment
3. In the fixed pouring water stop, should prevent water stop shifted, affecting the sealing effect.
4. plastic water stop connector available adhesive, heat welding, etc., to ensure that the joint firm.
5. concreting process should pay attention fully vibrating, water stop and concrete in order to achieve full
