Water stops, also called water bars, are tape-like parts of a concrete structure that stop water from getting through the joints. Concrete joints are most liable to seepage. They are fluid-tight diaphragms built into the joints or run along them. The connection is as watertight as the water bar that holds them together. Please read this article if you have inquiries or concerns about the best PVC water stopper in Lahore.

PVC Water Stopper

Joints are a necessary part of large concrete structures like retaining walls, basements, reservoirs, and tunnels. It may be building or expansion joints, or both. A water bar protects joints that are in direct contact with water. They are strips of water-resistant or water-proof material cast into the joints of the concrete to stop water from getting through.

Setting up Water Stoppers

Water stops are put in the middle to stop water from getting in from the face of the slab or the wall. Before the concrete pouring, put them into place in the formwork carefully. On the other hand, nailing through an outboard flange makes it easy to fix water bars outside. These stop water from getting in from outside the building. Most piled-wall basements have water stops on the outside of the walls. The main job of a water bar is to seal the joint so that water cannot get in. It makes it possible for two parts to move freely and independently of each other. PVC water stoppers are welded together with heat and never lapped. Waterbars come in long rolls.

How do water stoppers or water bars work?

Water stoppers are used in the building industry to keep water out. Waterbar is used to improve the quality of buildings in the water and transportation industries. Common places to use structures are:

  • Water and sewage disposal projects
  • Liquid containments
  • Tanks, tunnels, channels, and dams
  • Locks and box culverts
  • Primary and secondary structures for keeping things in
  • Bridges and the edges of decks
  • Wall and pieces
  • Cellars and basements

Different Water Stoppers Tape Types

There are a few main types of water stops to use in buildings. These types depend on the job and the available products. The right water stop depends on the building type, its level of exposure, and how it was built. There are different kinds of water stops made of different shapes and materials. Water stops are available in the following groups based on the material.

PVC Water Stopper

It is the type that most people have. It has high tensile strength and is resistant to acids, diesel oil, chlorinated water, and other chemical liquids. They don’t change the color of the concrete. Also, there is no electrolytic action with the reinforcement around them. It is very flexible and does not let water through. The outer flanges of a PVC water stop can be attached to nearby reinforcing bars, which makes it easy to put in place.

HDPE Water Stop

High-density polyethylene helps to make this. It is strong, lasts longer, and can handle temperature changes well. It doesn’t tend to swell up and is resistant to both oxidants and accents that make things shrink. HDPE water stops are useful for sewage treatment plants, chemical plants, and primary and secondary containment structures.

TVP Water Stop

It is made of rubber and plastic mixed. It is easy to butt-weld TVP water stops. It has good resistance to dynamic fatigue, a high elasticity, and high resistance to long-term changes in temperature. TVP is also good for the environment and stands up well to weather and UV light.

Rubber Waterbar

This type of water stop is very good at handling high movement. It can adjust for subsidence and seismic movement. Moreover, it can handle a high hydrostatic head. Its use is perfect for joints that move a lot.

The water stops are strips of water-repellent or water-proof material cast into the joints of the concrete to stop water from getting through.

Using PVC Water Stop Tapes

After getting information about water stop tape types, it is time to apply them. The right way to use water stop tape depends on how well it stops water and other chemicals from getting in. There should not be any deviations or misalignments. The best way to put up the PVC water stop tape is to attach it to the steel frame around the outside. So, if you want an easy installation of a PVC water stopper, Millat Rubber experts can help.


You will fix the water stop in the concrete with a slide mold or another method that works well. It makes sure that it is in the right place. The tape that stops water from getting in is put right in the middle of the connection. Shake the concrete around the water stop to avoid any gaps or honeycombs. Also, make sure the concrete sticks well to the water retainer rods.


To make the addition, soften the ends of the water stop tape over an indirect heat source until they have a melting point of 200°C10°C. We recommend welding irons with a Teflon coating and thermostatic control. When the plastic starts to melt, the ends line up. It must be held firmly for about 20 seconds until the plastic cools.
