PRONIL ACR-300 hydrophilic acrylic cord, 10x20 mm (10-meter roll)

Acrylic waterproofing swelling cord 10×20 mm is designed for sealing construction joints, connections and utility penetrations in concrete structures.

Upon contact with water, the material gradually swells and increases in volume by up to 300%.
In a confined space, the cord tightly fills cracks, pores and irregularities, creating a reliable barrier against water penetration.

Thanks to its simple installation and resistance to salt water and various chemicals, the acrylic cord is used in underground, hydraulic and civil construction.

Where the acrylic cord is used

• in swimming pools and water tanks;
• at wastewater treatment facilities;
• in structural and construction joints of concrete structures;
• at wall-to-foundation connections;
• for sealing penetrations of engineering utilities through foundation walls;
• around PVC pipes at building entry points;
• as a waterproof sealing flange;
• in structures that come into contact with seawater or salt water.

Main advantages

• increase in volume of up to 300% under the action of water;
• controlled swelling without damaging the concrete;
• reliable sealing of cracks, pores and irregularities;
• resistance to salt water and chemicals;
• versatile application;
• quick and easy installation;
• does not require special installation equipment.
