What is the reason for the ground cracking after leveling?

If there are cracks on the ground after leveling, first determine whether to level with cement mortar. The main causes of cracks after using cement mortar are too much cement in cement mortar, too large cushion area, non-layered and segmented pouring, uneven settlement of ground backfill and insufficient thickness. Water is not timely during maintenance, and cement dries too fast. At the same time, another reason is that the ratio is unreasonable, which leads to the non-solidification of water and sediment.

If this kind of problem occurs, the solution is to knock the crack open, carefully check the situation, find out the causes of the crack, and see what kind of crack it belongs to, such as ground crack, right-angle crack, outline crack, irregular figure-eight or twill. Every kind of crack has different reasons, so we should observe the situation of these cracks first. Experts from Fivas Floor Company explained that the solution is to backfill the material at the crack, and the backfill should be compacted and must be compacted. If this situation is serious, it can only be knocked out and repaved with cement.
