Pressure Grouting Concrete Cracks

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.

Pressure grouting concrete cracks.

On the day of grouting all the plugs are removed to drain out excess water and restored before commencing grouting. This method is effective in sealing the crack in concrete but it will not structurally bond cracked sections. The process of grouting of concrete cracks is repeated with other holes till all the holes are covered. 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.

When a high pressure pump is used a higher quality and more flexible grout can be used. A high pressure pump forces the liquid grout into the entire crack no matter how small the crack is. Pressure crack injection can be used to stop leaks seal cracks and restore strength of cracked concrete. 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.

Epoxy crack injection utilizes epoxy grout to structurally weld cracks to permanently restore the integrity of a structure. A flexible grout can take some movement without cracking and failing. The injection of a cement based grout is a widely used and well known method of lifting concrete slabs that have settled. This procedure which is often referred to as pressure grouting or slab jacking can be a great alternative to replacing existing concrete slabs.

There are two types.
