The Correct Way of Relevelling Piles
Relevelling is needed in buildings where the old concrete stumps have already caused unevenness in the soil. Deformation of soil accompanying concrete growth is a cause for structural stability issues. Deformation occurs because of the pressure of people, soil vibration, and temperature changes. Sand and clay also shrink in the sub-grade are usually the main causes for soil subsidence. The method of leveling involves the use of heavy-duty hydraulic pumps to raise portions of the structure as needed. Water is introduced to the space by a series of drains. Pipes carrying water to the different areas on the foundation are also fitted. This helps reduce the amount of labour required for the job. The pump removes whatever water is in the space that needs to be raised and the soil is pumped back to the original position. It is important to obtain building consent before embarking upon any such activity. If the foundations of an apartment or commercial building have been built without ...
