Drybase Waterbar

Drybase Waterbar consists of a hydrophilic acrylate based swelling substance, embedded in a butylene copolymer based thermoplastic elastomer, with reversible swelling properties.

After contact with water, the product swells up to 900% in volume. The pressure of the swelling action will cause it to expand in the joints, filling all cavities and thereby stop the water flow. Reversible expansive properties, dimension remains stable. The waterbar does not entrain water through its structure. The swelling process is limited to the water contact surfaces.

Features and benefits:

• Highly flexible, easy application.

• Resistant to water pressure up to 2 bar.

• Also suitable for zones with tidal water movement.

• Suitable for contact with sea water.

• Temporary swelling protection in case of premature water contact.

• The swelling process is reversible.

Applications:

Suitable for use in waterproof construction joints and pipe inlets in concrete structures exposed to permanent or temporary hydrostatic pressure.
