Check crack area and clean the surface with a wire brush or grinder.

Drill holes near cracks using a hammer drill at a 45° angle from the surface to prevent packers from penetrating through the crack.
Position holes in a zigzag pattern, with each hole separated by a gap of 15-20cm.

Insert packers into the drilled holes and fasten tightly using a T-wrench.

Pour PU Foam 20 C into a plastic bottle.
Mix with the Accelerates

Connect the grease coupler with the installed packer, starting at a low area and moving to the upper area (down-up).

Inject PU resin into the hole, starting with low pressure and gradually increasing. Stop injection when PU resin flows out from the cracks and move to another packer to repeat the process.

After injection, remove packers using a hammer. Clean the surface with a scraper or grinder, and if needed, coat with sealing materials. Damaged areas can be sealed with polymer modified mortar using Repair Polymer.

After injection grouting, clean the machine properly using xylene thinner. Pour the thinner into the jar of the grouting machine and follow the cleaning procedure.

Close the cap after use to avoid moisture exposure.
Wear protective clothing, gloves, and goggles while working.
In case of skin contact, rinse with water and soap for several minutes.
In case of eye contact, rinse cautiously with water for 15 minutes and seek medical attention.
