Sikaswell joint hydro gonflant

Hydroexpansive rubber profiles, also known as hydroexpanding profiles, are essential elements for waterproofing joints in various structures, particularly in concrete structures exposed to water, such as tunnels, foundations, and reservoirs.

Features of hydroexpansive profiles:

- Composition: These profiles are typically made from synthetic rubber, which allows for good flexibility and chemical resistance.
- Functioning: When exposed to water, these profiles absorb moisture and swell, creating a watertight seal. This swelling allows for compensation of movements and any potential cracks in the concrete.
- Applications: They are often used to ensure the watertightness of construction joints, expansion joints, contraction joints, and connection points between different materials.

Advantages:

- Efficiency: Excellent ability to create a barrier against water, even under pressure.
- Durability: Resistance to wear and aging, ensuring a long life span in difficult conditions.
- Ease of installation: Often available in rolls or strips, they can be easily applied to desired surfaces.

Implementation:

- Surface preparation: The surface must be clean, dry, and free of any substance that could affect adhesion.
- Installation: The profiles are generally fixed in place with a compatible adhesive product or keyed into the joint during the pouring of concrete.
- Inspection: After installation, it is important to check for the absence of defects that could compromise watertightness.

Conclusion:

Hydroexpanding rubber profiles represent an effective solution for the waterproofing of restoration joints. They combine performance and durability, making them a preferred choice for water-sensitive constructions. For a successful application, it is recommended to follow the manufacturer's recommendations and ensure that the installation meets current standards.
