The most common method of underpinning is the mass pour method. This process requires excavating sections in sequence to a pre-established depth below the footing and placing concrete in each pit. Then, this process is repeated until the entire affected area has been underpinned.
How to Underpin a Foundation?
How to Underpin a Foundation Underpinning a foundation is a process to reinforce the stability of the foundation and to ensure that it can handle the load of the structure that it supports.
It is an important step in the construction process and should be done correctly to ensure the safety and longevity of the building. The first step in underpinning a foundation is to assess the existing foundation.
This includes looking for signs of damage or settling, such as cracks in the walls, uneven floors, or doors that don’t latch properly.
If there are signs of damage, the foundation should be inspected by a structural engineer to determine the extent of the damage and the best course of action.
Once the damage has been assessed and a solution is determined, the next step is to prepare the ground for the new foundation.
This includes excavating around the existing foundation and removing any debris or soil that may interfere with the process.
The soil around the foundation should be compacted to provide a stable base for the new foundation. Once the ground has been prepared, it is time to start the underpinning process.
This is done by excavating around the existing foundation and inserting piers, beams, or posts into the ground to support the existing foundation. Depending on
