concrete slab lifting refers to the phenomenon that the concrete slab lifting of a building will sink and tilt due to external forces, uneven forces or soft soil. concrete slab lifting will not only cause instability of the foundation, but also cause serious consequences such as building tilting and structural damage. In order to ensure the normal operation of the equipment/normal use of the building, our technicians have developed the "non-destructive and controllable soil solidification technology" to solve many problems of concrete slab lifting sinking and tilting.

"Non-destructive and controllable soil solidification technology" through the injection of special composite materials in the soil layer, so that the gap in the soil layer is supplemented, through penetration, filling, compaction and other forms, so as to achieve the purpose of strengthening the foundation. This method can not only strengthen concrete slab lifting, increase the stability of the foundation, but also restore the original height and avoid the problems of incline and displacement of the building.

In the actual process of concrete slab lifting, pay attention to the following points:

1. Formulate reasonable technical plans according to geological characteristics to ensure the engineering effect;

2. Arrange grouting holes according to the specific situation of the site;

3. Strictly control the flow rate and speed of grouting slurry, monitor the grouting results in real time, find and solve problems in time;

4. After the completion of the project, timely quality inspection and acceptance to ensure that the quality of the project meets the requirements.
