Concrete structures exposed to extreme conditions, like intense heat, are subject to higher damaged in its crystalline structure, which can result in a higher porosity. Old concrete may have also lost some of its integrity due to external influences, carbonatation 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 filtrations in the structure.
KÖSTER Injection Gel G4 is an extremely low viscosity acrylic gel that intelligently follows the paths of water ingresses, 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. 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.
