Treatment methods of cracks in houses

If the wall cracks extend for a long time, both the wall and the ground exist, which is generally the floor expansion joint left by the pouring of the big tower, which belongs to the normal structural cracks.

Temperature crack

Temperature cracks are common cracks in houses and will not affect the overall structure of houses. In this case, non-woven fabric, PVC grid cloth or mortar can be pasted at the crack, then brushed flat with putty powder, and then repaired with paint.

Joint crack

Cracks often appear at the joints of new and old walls, which leads to the deformation of the whole building tends to be stable and easy to be repaired repeatedly in a short time.

Foundation settlement

After the house is built, the foundation is easy to sink. If the foundation settlement is uneven, shear force and tensile force will easily occur at the wall, and cracks will occur if the tensile shear strength of the wall itself is exceeded.

Basic treatment

If there is a problem with the wall base, you can also do a fundamental treatment in this piece first. But also can prevent the wall from cracking again in the future. If you shovel off most of the wall skin, it will be easier to strengthen the wall in the later stage and better bond with Dabai. This material can make the grass-roots clean up more cleanly, increase the adhesion of the wall surface, and make the gypsum putty and the wall surface bond more firmly in the later period. This is a very important building restoration, so don't ignore it.

Wall treatment

This part of the sunken wall can be leveled with fast dry powder first. This layer can be made thinner because there is still some work to be done later. In order to strengthen the wall, it is best to let the worker master hang a layer of wall fiber net during maintenance. This material can control the slight shrinkage of the wall, so that the white and paint of the wall will not crack with the deformation of the wall.
