Active water leaks in reinforced concrete structures pose serious risks, both structurally and aesthetically. Poly-Inject PB 535 , a solvent-free polyurethane injection resin, provides permanent sealing in cracks and joints. Upon contact with water, it expands up to 38 times, completely filling the crack and integrating with the concrete.
Why Choose Poly-Inject PB 535?
Thanks to its low viscosity formula that can be applied with high pressure, it reaches even the smallest cracks.
Its solvent-free and environmentally friendly structure allows it to be used safely in drinking water tanks.
With its flexible and semi-flexible options, it adapts to structural movements and reduces the risk of cracking or separation.
Thanks to its fast reaction time, it offers a great time advantage in emergency repairs.
Ease of Application with Poly-Inject PB 535
Surface preparation: Loose particles in the crack are cleaned, cracks larger than 3 mm are sealed with Merks Stop CB 501 beforehand.
Packer placement: Placed at a 45° angle, the distance is adjusted between 15–90 cm.
Injection: Start with low pressure and gradually increase the pressure until the resin begins to overflow.
Completion: The process is completed after resin exits from all packers.
Poly-Inject PB 535 Usage Areas
Tunnels and infrastructure projects
Dams and water channels
Underground parking lots and basements
Drinking water tanks
Underpasses and metro lines
Poly-Inject PB 535 Durability
Poly-Inject PB 535 expands upon contact with water, completely filling cracks. It integrates with the concrete, preventing the formation of new waterways. It offers high resistance to chemicals, water pressure, and freeze-thaw cycles. It can be stored for up to 6 months under appropriate conditions.
Poly-Inject PB 535 offers high performance, rapid application, and a permanent solution for preventing active water leaks. Its reliable performance, even under high pressure, makes it indispensable for professional waterproofing projects.
