Concrete structures exposed to extreme conditions, like intense heat, are subject to higher damaged in its micro structure, which can result in a higher porosity and cracking. Old concrete may have also lost some of its integrity due to external influences, or possible prolonged water filtrations. Bad concreting or poor vibration can as well be causes of unwanted honeycombs or cracks on the surface. All these situations required an intelligent system with the capacity to fill the finest cracks and voids and stop water filtrations through the structure.

Although concrete injection is not the most commonly injection performed, it belongs to the fields of applications of the acrylic gels. Once again, the low viscosity of the material and the safe curing without affecting the steel reinforcement, make concrete injection a specialized field of application for the KÖSTER Injection Gels.

KÖSTER Injection Gel G4 is an extremely low viscosity acrylic gel that can intelligently follow the paths of water ingress, and after curing, seals filtrations effectively from the source. The structure is drilled in a specified pattern, depending on the dimensions and conditions, and KÖSTER Superpackers are inserted into the drill holes. The KÖSTER Injection Gel G4 is injected in one or multiple phases until a pressure resistance is achieved. Afterwards the packer holes can be filled with KÖSTER KB-Fix 5.

Always adhere to the specifications in the respective Technical Guidelines.
