What exactly causes the subsidence and depression of the factory building floor? What professional sedimentation treatment solutions are there? Come and learn about it together with Soft Foundation.

Reasons for tank floor instability treatment

1. Problems with the foundation itself

Either due to poor soil quality of the foundation or improper foundation treatment, the tank floor instability treatment occurs. If there are rivers or lakes near the factory building, such problems are more likely to occur as the underground soil layer is mostly soft soil formed by alluvial deposits.

2. Excessive load

If the weight of the equipment exceeds the maximum designed load or the machine has a large dynamic load, it can also lead to tank floor instability treatment. Generally speaking. Similar problems are prone to occur in heavy machinery processing workshops, forging workshops, casting workshops, etc.

3. Changes in the external environment

Heavy rainfall or drought causes changes in the groundwater level, which has a significant impact on the stability of the factory building ground. When the groundwater level rises, the foundation soil will soften due to water immersion, the soil strength will decrease, and the bearing capacity will decline. The decline of the groundwater level may lead to an increase in the effective stress between the particles of the foundation soil, triggering the compressive deformation of the foundation soil. For instance, during the rainy season, the groundwater level rises. If the drainage system of the factory building is not smooth, the problem of ground subsidence is likely to occur. Excessive extraction of groundwater can also cause regional groundwater levels to drop, leading to the settlement of factory building foundations.

Traditional ground subsidence treatment solutions such as pile driving, cement grouting, and demolition and reconstruction all have different hidden dangers. Moreover, they only address the symptoms but not the root cause, and subsequent subsidence may occur.

Soft Foundation independently developed non-excavation settlement repair technology to address ground subsidence issues. After injecting new composite materials, through methods such as infiltration, filling, and compaction, water and air in the soil layer voids are squeezed out and consolidated with the soil to form a composite foundation. As the pressure and density of the soil layer increase, an upward lifting force is formed, thereby achieving the purpose of ground leveling.

The non-excavation settlement repair technology for soft foundation can reinforce up to 60 meters. It specifically analyzes the bearing stratum based on geological conditions and usage requirements to ensure that the reinforcement depth passes through the bearing stratum as support. Moreover, the solidification time of this material is controllable in seconds and is widely applicable to adverse geological conditions such as silty soil, collapsible loess, silt, sandy soil, and high backfill.
