Repair and reinforcement of floor cracks

​In order to prevent the corrosion of steel bars in the plate and the increase of the cracks, it is necessary to use crack injection adhesive for repair crakcs. At the same time, in order to prevent the stress concentration of the cracks, the carbon fiber wrap concrete repair system should be used in the cracked parts.

Project overview

Cracks appear on the floor, cracks develop outwardly, and local cracks have been breakthrough.


Analyzes causes of concrete cracks

1.The steel bar is misplaced of slab, and the protective layer is too large, resulting in the decrease of the bearing capacity of the structure, causing cracks.

2.The upper part of the slab is cracked due to the lack of reinforcement on the top plate.

3.Expansion cracks caused by temperature stress
