Slab crack repair

Project overview

The living room is inclined to a crack. In the part of the bedroom, there is a crack of the slab (the cracks in the north and the south). In order to prevent the corrosion of steel bars in the slab, crack injection should be carried out. Carbon fiber reinforcement is proposed for the cracked parts.

Strengthening materials

HM-120ML crack repair adhesive

HM-120L crack injection adhesive

HM-30 carbon fiber reinfroced polymer(CFRP) fabric

In this project, the cracks in the floor, preliminary identification of cracks is developed from bottom to top, from the structural safety angle, the crack width is not greater than 0.2mm through using epoxy crack injection adhesive. And penetrating crack must be reinforced of carbon fiber cloth.
