Hydrophilic Swelling Waterstop

Hydrophilic Swelling Waterstop

Hydrophilic swelling waterstop profiles and sealants work well in construction joints. They are ideal for commercial and residential underground structures. These products are effective with low to medium groundwater pressures.

Applications include:

• Pipe and steelwork penetrations through walls and floor slabs.

• Connecting joints in diaphragm walls.

• Construction joints in in-situ and precast concrete.

• Cable ducts and more.

Hydrophilic expandable waterstops, also known as swelling rubber waterstops, seal joints in concrete. They stop moisture and water from getting in. These waterstops fit many types of joints, such as cold joints and construction joints. These waterstops can expand over 400% in volume when they get wet. This creates a flexible and watertight seal.

Manufacturers make polymer waterstop from vulcanized rubber. It seals concrete joints by using swelling pressure to stop water. Polymer waterstop outperforms bentonite and other swelling water stops. It has better swelling pressure and stops water more effectively. It works well with both regular groundwater and water contaminated with salt and sulfate. Polymer waterstop is extremely durable and will not deteriorate over time.

Notes to be Observed

Cold joints and construction joints are spots in concrete structures. They are weak points where leaks and cracks can happen. This is mainly due to water getting in. Unchecked water ingress can lead to many issues that damage a structure’s integrity, like:

Rebar corrosion:Water can get in and corrode the reinforcing steel. This may weaken the structure as time goes on. Expansion cracks happen when water seeps into concrete. This water causes pressure that creates cracks. Frost and thaw cycles can harm concrete. When it freezes and thaws repeatedly, concrete structures suffer, especially in cold areas.

Health hazards: Mold and fungus can grow when moisture seeps in. This can harm the health of the people living there.

Using hydrophilic expandable waterstops in cold and construction joints helps builders reduce risks. This ensures the longevity and stability of concrete structures.
