PVC PE water stop extrusion line

In order to help water flow and to ensure long-lasting use, large sized concrete pipes are usually lined inside with ceramic tiles.

To avoid high production costs a HDPE sheet application has been devised as inside lining. This sheet has a particular profile which allows its installation and anchoring in the concrete at the time of the casting process, by means of a series of longitudinal T’s.

This means that the inside of the concrete pipe is indeed like the inside of any standard HDPE pipe, with all resulting advantages.

This particular HDPE sheet is manufactured using a special calender with contoured rollers which produce the longitudinal T’s. A highly efficient cooling system enables to obtain sheets up to 4 mm thick.

In recent years the market of HDPE liners with V-Stud has developed enormously, for use in concrete structures, ensuring perfect anchoring.

China GWELL PVC PE water stop extrusion line is made of PVC Soft Sheet Extrusion Line high-grade PVC composite. They are designed to seal movement and construction joints in reinforced concrete structures.

PVC PE Water Stop Extrusion Line, used in concrete to seal construction and expansion joints, embedded in concrete, through and along the joints, forming a continuous waterproof membrane that prevents fluids from passing through the joints.

China GWELL also proposes a different geometry instead of a T-shape. This is according to customer’s request.

Plastic water stop plate is a water stop material made of high-density polyethylene (HDPE) and polypropylene (PP) resin by extrusion molding process.

The plastic water stop plate is mainly used for the foundation works that are set in the construction joint and deformation joint and form a body with the concrete during concrete pouring, such as tunnels, culverts, diversion aqueducts, retaining dams, liquid storage structures, underground facilities, etc;

It uses the elastic deformation characteristics of polymer materials to prevent leakage and seepage in building structural joints and has the characteristics of corrosion resistance and good durability.
