Resin injections are the most effective method for treating/repairing cracks in reinforced concrete elements. In this technique, the pouring of resin into the crack is performed via injection ports adjusted to it, after first sealing the crack with resin putty. The main advantages of this method are the excellent compatibility of this material with concrete and the high durability over time.
Cement grout injections are used for filling cracks in load bearing masonry or stone frame constructions. The injection of cement grout into the crack is carried out through injection ports adjusted to it, after first sealing the crack with high strenth cement mortar. Alternatively, in cases of historic buildings, instead of cement grout injections, natural hydraulic lime injections can be used.
Natural hydraulic lime has the advantage of having a similar composition to the existing adhesive mortars, therefore not causing spots of increased stiffness in various locations of the building element under repair.
