PVC plastic waterstop is also known as "plastic waterstop". It is made of PVC PVC resin and various fillers through mixing, granulation, extrusion and other processes. It is a waterstop product made by mixing, granulating, extruding and other processes. This product takes advantage of the elastic deformation characteristics of elastomer materials to play the role of leakage prevention and seepage prevention in the construction joints, and has the characteristics of corrosion resistance and good durability.

Plastic waterstop, which makes full use of the elastic deformation characteristics of PVC resin, plays a role of leakage prevention and seepage prevention in the construction joints, and has the characteristics of corrosion resistance and good durability. The specifications of plastic waterstop are 280 × 6300 × 4300 × 6300 × 8300 × 10350 × 8350 × 10, etc. PVC plastic waterstop is mainly used in the construction joint and deformation joint during concrete pouring, which is integrated with concrete. Such as tunnels, culverts, aqueducts, dams, liquid storage structures, underground facilities, etc.

Construction method of PVC plastic waterstop

The construction method of plastic waterstop is the same as that of rubber waterstop. In the process of pouring and burying, the interface between the concrete and the concrete should be smooth, and the joint part should be firmly bonded. In the process of pouring and burying, the concrete should be fully vibrated with appropriate force to make it well combined with the concrete, so as to obtain the best water stop effect.

Precautions for PVC plastic waterstop construction

1. In the construction process, due to many sharp corner stones and steel bars in the concrete, attention should be paid to avoid mechanical damage to the waterstop.

2. When positioning the plastic waterstop, the interface between the plastic waterstop and the concrete should be smooth, and the waterstop should not be overturned or twisted. Otherwise, it should be adjusted in time

3. When pouring the fixed waterstop, the deviation of waterstop should be prevented to affect the water stop effect.

4. The plastic waterstop joint can be bonded and welded to ensure the joint is firm.

5. In the process of pouring concrete, attention should be paid to sufficient vibration to achieve the full combination of waterstop and concrete.
