The foundation backfilling of rural self-built houses is a crucial link, so when carrying out foundation backfilling, it is important to pay attention to the following 3 problems, let's take a look!
First, the choice of backfill time
When building houses in rural areas, reinforced concrete is usually used as the main building material. These materials require a certain amount of time to be cured after pouring to ensure that they reach their optimal strength.
In general, reinforced concrete needs to be cured for 7 to 10 days. During this time, the concrete gradually hardens and strengthens to achieve the strength required for the design.
Therefore, the best time for backfilling should be 7 to 10 days after the curing of the reinforced concrete. If backfilling is carried out too early, it may cause the concrete to be squeezed and deformed, which will affect its structural performance.
Late backfilling may result in the foundation being exposed for a long time, increasing the risk of being exposed to external factors. Therefore, it is crucial to choose the right time for backfilling.

2. Ensure that the indoor backfill is evenly filled and compacted in place
When carrying out foundation backfilling, it should be ensured that the indoor backfill is uniform to avoid local unevenness. The backfill material should be selected to meet the requirements of sand, gravel, etc., to ensure the quality of the backfill.
At the same time, in the process of backfilling, professional tamping equipment should be used to fully tamp the backfill material to ensure that the backfill density meets the design requirements.
The importance of tamping in place is to ensure that the backfill material is tightly integrated with the original foundation to form a whole, thus improving the stability of the house.
If the backfill is not compact, it may lead to problems such as settlement and cracking during the use of the house, which will seriously affect the safety and service life of the house.

3. Pay attention to the control of the backfill height difference
When building a house in the countryside, there is a certain difference in the height of the backfill between the yard and the interior. In general, the backfill height of the yard is about 45 cm higher than that of the interior. This design is mainly to facilitate drainage and prevent rainwater from backing up.
If the backfill height difference is not properly controlled, rainwater may not be able to drain smoothly, resulting in water accumulation in the hospital or rainwater backing up into the room.
This will not only affect the normal use of the house, but may also pose a threat to the structural safety of the house. Therefore, when carrying out foundation backfilling, it is necessary to strictly control the backfill height difference to ensure the smooth drainage system.
