Cracks in concrete floors are a common problem that can have various causes, whether it is subsoil settlement, concrete shrinkage, incorrect design of the structure, or mechanical damage. Regardless of the cause, it is important to repair cracks in time and properly to prevent further spread and deterioration of the floor.
Types of cracks and their impact
Static cracks: These cracks are not caused by structural movement and usually do not propagate. Their repair consists in injection with epoxy resin or another suitable strengthening substance.
Dynamic cracks: They occur due to the movement of the structure and require more complex repair. This includes cutting and widening the crack, inserting steel clips and then filling with epoxy resin.
The method of repairing cracks in a concrete floor depends on several factors
Type of crack: Static cracks are easier to repair than dynamic cracks.
Crack size and depth: Larger and deeper cracks require more difficult repair.
Crack Location: Cracks in exposed areas with heavy traffic require a more durable repair.
Required level of strength: The repair should restore the required bearing capacity and stability of the floor.
Crack repair methods
Epoxy resin grouting: Epoxy resin flows into the crack and, after hardening, strengthens and stabilizes it.
Insertion of steel clips: Steel clips are used to reinforce and stabilize cracks in dynamic structures.
Filling cracks with mortar: For smaller cracks, mortar is used, which, after hardening, is flush with the surface of the floor.
Covering cracks: In exposed areas, cracks can be covered with steel sheets or other covering materials.
Important aspects of repair
Before the repair, it is necessary to find out and remove the cause of the cracks. Otherwise, cracks may reappear.
The repair should be carried out by an experienced specialist using appropriate materials and technologies.
After the repair, it is necessary to follow the instructions for curing and loading the repaired area.
