The self-built three-story house in the countryside is cracked. The first floor was built in 2006. The foundation was dug one meter deep by hand. There is a cement floor and eight-eight-shaped floor beams underneath. There are no ring beams on the first floor...

According to the situation you described, it is entirely caused by uneven settlement after increasing the load. If the cracks continue to develop and widen, the building will become dangerous and uninhabitable. The cement floor under the original foundation cannot be used as a foundation. Now the cement floor has fractured and sunk. Generally, the lower part of the cement floor has not been subjected to any stress treatment, so it will have to sink in the future. It is recommended that you observe the cracks frequently.
