PVC PE water stop extrusion line

As China Plastic Extruder Supplier, GWELL produces plastic waterstops which are waterstops made of high density polyethylene (HDPE) and polypropylene (PP) resins through  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.

Features :

1. PVC Water stop Conical Twin Screw Extruder


For PVC Rigid Sheet Extrusion Line,PVC powder, the PVC water stop making machine should include: mixer, SJZ conical twin-screw extruder, die, 4m cooling tank, tractor, cutting machine, winder


2. PVC water stop single screw extruder


GWELL as China Plastic Extruder manufacturer, PVC PE Water Stop Extrusion Line For PVC granules, the PVC water stop belt manufacturing machine should be a single screw extruder, a die, a 10-meter cooling tank, a tractor, a cutting machine, a winder, etc.


China GWELL, as a manufacturer of soft sealing profiles for PVC water-stop profiles, PVC profiles are mainly used in the building and construction industry, such as door panels and frames, PVC ceilings, window frames, edge strips, building corner profiles, etc.

China Plastic Extruder manufacturer the product PVC plastic waterstop is mainly used in foundation engineering, which is composed of concrete in construction joints and deformation joints during concrete pouring. Such as tunnels, culverts, aqueducts, dams, liquid storage structures, underground facilities, etc. The plastic watertight tape makes full use of the elastic deformation characteristics of PVC resin in the construction joint to prevent leakage, and has the characteristics of corrosion resistance and durability.

  1. Where the expansion joint, settlement joint, construction jointand other structures are disconnected and waterproof must be done, water stop must be set.
  2. For the cast-in-situ concrete structure in the basement of civil air defense project, the construction joint at the junction of foundation and wall, the deformation joint at the junction of civil air defense channel and main structure, cast-in-situ concrete septic tank and reservoir, and the construction joint at the junction of bottom plate and wall must be provided with water stop.
  3. For thermal pipe trench with waterproof requirements and cast-in-situ concrete thermal trench, water stop must be set at the construction joint and deformation joint.
  4. Conical twin-screw specially designed for PVC powder raw materials.
  5. China GWELL PVC PE Water Stop Extrusion Line adapts to different moulds of different PVC profiles.
  6. With specially designed vacuum calibration platform, traction and cutter, and stacker.
  7. The profiles are cooled by all-round efficient water mist.
