Concrete crack repair, how to fix cracked concrete

Drill Ø12mm holes, in staggered row, in each side of the concrete crack with a 45° angle to reach it in depth. Remove the dust with an air blown gun.

The anchoring sleeves are inserted in each drilled hole, using a hammer until a perfect fit. With a mounting tool, hammer strongly the injectionpacker into each anchoring sleeve.
The anchoring sleeve expands and firmly holds all together.
For vertical cracks, seal the crack in surface with a waterproof material to avoid the resin to come out.

Inject gradually the injection resin depending on the concrete condition. Only use officially approved chemicals and equipment; wear the Personal Protective Equipment required.
After injection, the injection-packer head can be immediately cut and holes must be resealed.
