Housing appraisal is very important. When the foundation sinks in the house, it is necessary to entrust the specialized housing structure safety inspection and appraisal department to carry out housing appraisal in a timely manner, so as to provide a scientific and reliable basis for the subsequent safe use and restoration. Share how to determine whether the foundation is sinking:
1, cracks in the wall, floor phenomenon
The main signal of foundation settlement is the cracks in the house and its walls. The cracks caused by the sinking of the foundation are usually diagonal. For example, wall cracks suddenly appear on the limestone walls inside the house or the masonry outside the house. The cracks generated by the sinking of the foundation are usually wider than the hairline cracks, which are caused by the natural movement of the structure, and the top of the crack is usually wider.
2, cracks in pile foundation and chimney
In addition to wall cracks and floor cracks, cracks may also appear in the base and chimney. Due to the settlement of the house, the chimney may tilt.
3, road uneven
Road subsidence and street road subsidence in the vicinity of houses are usually seen as potholes, depressions and uneven surfaces.
4, doors and Windows stuck
Signs of foundation subsidence occur at weak points in the house, such as doors and Windows. Because the house has been displaced, it can be found that the doors and windows are stuck. The reason for the jam is that the foundation has settled, usually at the seams of the house, and the ground and the extension of the main structure have ground settlement. Therefore, the jammed doors and Windows may mean that they are moving or have been detached from the main structure.
