PVC Waterstop for Construction Joints

The most common solution to seal construction and expansion joints

When to use a PVC Waterstop

Our top-quality PVC waterstop are specifically engineered to provide a watertight seal in concrete joints and structures, offering superior performance and long-lasting durability.

You can trust in their ability to withstand high water pressure and resist chemical corrosion, protecting your structures from leaks and water damage. The exceptional flexibility and tensile strength make them suitable for accommodating movement and preventing unwanted infiltration.

Whether you’re working on commercial, residential, or industrial projects, our PVC waterstop is the ideal choice. Its versatility and compatibility make it suitable for a wide range of applications, ensuring optimal performance and longevity.

Different types of PVC Waterstop:

Construction Joint Waterstop

Designed to seal non-moving construction joints and prevent water infiltration, providing a continuous barrier from leakage.

Expansion Joint Waterstop

Their section includes a central bulb that is left outside of the cast. They are engineered to seal expansion joints while still allowing for movement.

Internal Joint Waterstop

This type of waterstop is placed inside the concrete structure, and it is secured to the rebar with clips that prevents it form moving during casting.

External Joint Waterstop

This type of waterstop is placed on the bottom end of the concrete structure, and it is used to seal the structure externally. It is usually secured with clips.

Application of Waterstop profiles

Positioning the joint in place

The joint must be unrolled and laid flat, in order to avoid any irregularities. It is important to fix the waterstop profile to the rebar using specific clips or wire.

The joint must be fixed to the steel structure multiple times, so it will stay safely in place when the concrete is cast. When using external waterstop joints it is even more important that the profile does not present wrinkles or deformities that separate it from the ground.

Welding with hot blade

Waterstop joint must form a closed barrier to protect the structure from water, so when using the product is very important to maintain its continuity. When a roll is finished, the end of it must be weld together with the beginning of the next roll.

This is usually achieved with the help of a hot blade, used to melt the two extremities together. It is important to inspect the joint for any irregularities and reheat it with the hot blade if necessary.
