Hydrophilic waterstops are installed in concrete structures to prevent water from leaking from or into joints by swelling when in contact with water and creating an impenetrable barrier. It also can help to minimise the impact of hydrostatic and hydrodynamic forces when the concrete structure is subject to movement structural stresses. Hydrophilic waterstops are designed to swell after construction with subsequent swelling when in contact with water. It will swell and block the intrusion of water. The waterstop can swell by up to eight times by volume in the presence of water and thus creating a pressure seal. When there is no moisture the waterstop will reduce back to original size. Many material types and profiles are available for different applications and conditions so the specifier must choose waterstops, preferably with manufacture consultation, appropriate for all the joint conditions. PRONIL specialises in manufacturing high-performance Hydrophilic Waterstops for construction for two decades.
The applications for PRONIL hydrophilic waterstops are not limited to cast-in-place concrete construction joints. Due to their flexibility and conformability, waterstops can be easily installed around pipe penetrations, I-beams, concrete pilings, and irregular-shaped surfaces. The company manufactures PRONIL ACR and BENTONITE hydrophilic waterstops.
PRONIL ACR: Hydrophilic Acrylic Swellable Bar for Construction Joints
PRONIL ACR is a new generation BBA Certified Product of new generation high-performance acrylic polymer-based expanding tape. It expands up to 900% when in contact with water. In a totally dry state, the product will shrink to its original installation dimension and re-expand on wetting. It is used in concrete construction for the sealing of construction joints including wall to base connections, pipe entry systems, sealing of openings and interface sections between existing and new concrete. It is easily stored in its original moisture-proof wrap in cool, dry conditions away from sunlight.
Advantages;
- Used on a variety of irregular substrates
- Forms an impermeable barrier against water in concrete
- Excellent compliance with deformed surfaces and joints
- Saves time and labour
- Easy to apply
- Simple overlap jointing on site
- No hardening time required
- No welding required
- Swell in salt water

PRONIL BENTONITE – Bentonite based waterstop for the effective sealing of concrete construction joints
Pronil natural sodium bentonite based hydrophilic waterstop is manufactured in Turkey. This product is a good alternative to conventional joint sealing systems. It will expand when in contact with water to form a positive seal in concrete construction including gaps, cracks, pores and capillaries.
Advantages;
- High hydrostatic resistance
- Fast and easy installation
- Seal is available in a range of sizes to accommodate irregular joint shapes, expands to seal off leaks
- Safe to use, non toxic therefore, no special handling is necessary
