Eliminates cracks in a concrete body using a high-pressure injection of ultra-thin, low viscosity epoxy compounds and microcements.

Injection is the technique of restoring and repairing reinforced concrete, stone and brick structures by injecting ultra-thin, low-viscosity epoxy compounds or microcements under high pressure into cracks through pre-installed packers (injectors). This procedure not only restores the integrity of the structure, stopping oxygen and moisture entrainment inside, but also cements its individual pieces and promotes the proper transfer of forces in the structure.

Cracks, seams, and voids are filled with injection materials. As they spread throughout the body of the structure, they make concrete and brickwork stronger, firmly sealing even the thinnest cracks. Epoxy and polymer-cement repair compounds are commonly used for cracks of various widths.

This technique has gained recent popularity in construction but has already established itself as an effective method of restoring the physical and operational characteristics of concrete and stonework structures.

Areas of use:

In industrial, cultural-social, public and residential buildings with reinforced concrete or stonework structures that require restoration of the integrity of beams, columns, walls, crosspieces, floor slabs, etc.

Injection procedure occurs as follows: 

⦁    Problem areas are identified and prepared by grinding along the entire length of cracks;

⦁    Cracks and seams are pointed and caulked using repair compounds;

⦁    Injection holes (bore holes) are drilled, crossing the cracks and installed packers; 

⦁    Repair materials (polymer cement, epoxy, polyurethane compounds) are prepared; 

⦁    Compounds are injected with constant pressure and flow rate monitoring, and waste is accordance with the design or until “refusal”;

⦁    Instruments are cleaned; 

⦁    After the compound cures, packers are removed and holes are caulked with a packing compound.
