What should I do if the floor of the frame house sinks?

If the settlement area is not large, you can make a 50-thick floor on it and add steel bars to level the ground.

Cause analysis of settlement:

1, the formwork support at the bottom of the slab is unstable, which leads to sinking during concrete pouring.

2, check whether the foundation settlement. In one case, it is no problem to continue adding layers; In another case, it can't fit.

3. When pouring floor concrete, the formwork will sink due to the ground subsidence, which will eventually lead to the concrete floor sinking.

It is clearly stipulated in the structural code that concrete members are allowed to work with cracks. As long as the crack width is within the allowable range of the code, the structural safety will not be affected.
