PRONIL ACR: Hydrophilic Acrylic Swellable Bar for Construction Joints

Hydrophilic waterstops protect concrete structures by preventing moisture infiltration. They are used to avoid the movement of the water through the construction joints and movement joints. A water-stopper installed in concrete joints is an important component of an overall waterproofing design to protect the concrete structure. Joints formed between adjacent concrete pours and where mechanical elements penetrate the concrete are the most likely points of water ingress into below-grade concrete structures. To prevent this from occurring, waterstops are commonly specified and installed. It is important the water-stopper be manufactured with quality raw materials, without defects. PRONIL specialises in manufacturing high-performance Hydrophilic Waterstops for construction for two decades.

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.

Application of PRONIL ACR in projects

PRONIL ACR can be used on a variety of irregular substrates. It forms an impermeable barrier against water in concrete. The product complies with deformed surfaces and joints. It saves time and labour and is easy to apply. No hardening time and No welding required for the product. It also swells in saltwater.

Wall applications
Tunnel applications

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 Acrylic Swellable Bars, Bentonite Hydrophilic Waterstops and Expansion Joint Tapes for construction for two decades. Apart from PROFLEX 3 they also have a wide range of Expansion Joint tapes and Waterproofing flexible Joint sealing tapes.
