Pressure Grouting Concrete Cracks

The injection of a cement based grout is a widely used and well known method of lifting concrete slabs that have settled.

Pressure grouting concrete cracks.

Epoxy crack injection utilizes epoxy grout to structurally weld cracks to permanently restore the integrity of a structure. Pressure crack injection can be used to stop leaks seal cracks and restore strength of cracked concrete. When a high pressure pump is used a higher quality and more flexible grout can be used. Cement grouting for cracks in concrete and masonry wide cracks particularly in mass concrete abutments piers and masonry substructures can be repaired by filling with portland cement grout.

There are two types. As the grout cures it produces a much finer pore structure. Applications of cement grouting for cracks. A flexible grout can take some movement without cracking and failing.

On the day of grouting all the plugs are removed to drain out excess water and restored before commencing grouting. The same sequence as described above is adopted for injecting the cement grout also. This method is effective in sealing the crack in concrete but it will not structurally bond cracked sections. Also there is usually a significant amount of grout that is forced outside between the wall and the ground to fill voids and make an additional water barrier.

Crack injection pressure grouting crack injection we use ultra low viscosity materials which can be injected to fill the narrowest of cracks up to 0 2mm in width thixotropic resins or cementitious materials are used for repairing cracks of greater width.
