Fix subsidence of buildings and structures
This can be achieved by strengthening the soil by using the Deep Injection Technology offered by Tesla Engineering. The procedure is a long-term solution for adding strength and bearing capacity of the soil by injecting polyurethane which expands to increase compaction and density of the injected layer.
During the soil improvement procedure, when the density of the soil increases, the foundation and the above structure is lifted. The rise of the structure can be detected and controlled with high accuracy by using a levelling laser.
Steps to improve soil strength
- First phase: inject to increase compaction and strength which will improve the ability to carry weight of the soil.
- Second phase: polyurethane expands to increase density and bearing capacity which will enable the soil to counter the current static load from above.
- The operation is carried out to cover the entire area to ensure that the soil improvement is consistent all around.
This procedure is very effective for areas that need to carry more weight and needs a higher bearing capacity of the foundation soil.
The polyurethane injection technology can be applied to fix subsidence, and increase strength and rigidity, in order to lift the entire structure back to its original level. A levelling laser is used to ensure that the height increase is accurate.
