Need of Underpinning:-

All types of foundation damages cannot be repaired by underpinning strategies. This repair method is only required if the foundation cannot fully support the structure which rests upon it. One of the most common factors is weak and unstable soil that causes foundations to lose stability. Many times your foundation became weak due to weathering. Changes in the structure also cause the foundation to lose its support efficiency. When you meet some of these problems, one solution is foundation underpinning.

If a faulty foundation or addition of second storey is the reason that may be an indication that soil subsidence is not the issue and concrete reinforcement may be the best method to use. If a nearby excavation caused the problem, another type of concrete reinforcement may be needed. If soil subsidence has caused your foundation to move or weaken, resin injection may be the best solution.
