Description
Technical Field
The invention relates to the field of building engineering, in particular to a process for repairing cracked and leaking water of a concrete floor slab.
Background
The concrete floor cracking is a special part which is easy to leak, and the reason for the water leakage is mainly as follows:
⑴ the engineering deformation is too large to exceed the allowable deformation range, mainly including expansion and contraction and uneven settlement of the foundation.
⑵ because the concrete is not compacted, it is loose, has dog-hole and honeycomb structure, and forms a water-leaking channel.
⑶ the water-proof property is not strengthened during construction.
Once the concrete floor cracks and leaks, the waterproof failure of the crack part is indicated. Therefore, comprehensive leakage treatment for structural reinforcement can be effective.
