Concrete Upgrading by Means of Water maximum-pressure Technology

Targeted Removal of Concrete with High-Pressure Pump Systems

Concrete upgrading by means of high-pressure technology enables a removal which is gentle and very precise.
Water high-pressure technology in the range between 2,000 and 3,000 bar is best suited for concrete upgrading: Coatings from fine mortar layers up to bitumen, or even contamination, can be removed simply with high-pressure water. In addition, damaged concrete can be broken open and removed, without damaging the reinforcing iron bars that are exposed. KAMAT high-pressure accessories for plunger pumps, such as the specially developed high-pressure gun, can used very selectively in this application and enabling fatigue-free, efficient working.

A KAMAT customer applied the high-pressure water technology with a KAMAT high-pressure pump system in case of a 17-floor multi-story building in Milan, in order to simultaneously eliminate a thick epoxy coating and defective concrete. The concrete upgrading on this building had become necessary after water had penetrated a to the reinforcing steel (which had had insufficient concrete covering it). These reinforcing bars and swelled due to corrosion and had broken open the concrete. The special KAMAT nozzles even at high pressure, enabled very precise targeting of the jet such that it could operate very near windows, expansion joints, antennae, cables etc., without damaging them.
