Underpinning is strengthening the foundation of a structure by increasing the depth or spreading the load across a larger area. Typically, this involves excavation of the soil from underneath and replacing it with a sturdier material like concrete. It works by adding extra concrete or steel footing under the building, providing additional support to the structure. This remedial process increases the foundation’s bearing capacity, allowing it to regain its structural stability.
Underpinning is essential for maintaining the structural integrity of a building, especially a tall one. Sometimes, foundations are fine without the need for additional support.
However, there are several cases where carrying out underpinning construction in Bristol is absolutely necessary. Not doing so can be risky and compromise the stability of the structure. Some examples are:

This is a traditional method of underpinning foundations in Bristol. It involves excavating weak soils from under the foundation (in sections) and filling them with concrete. This way, a strong foundation is built underneath the old, existing one. The method is straightforward, quick, and low in cost, but it works best with simple structures that have shallow foundations.
In cases where firm soil is a few layers below the foundation, we opt for piled underpinning. The remedial system involves the removal of upper internal floors and installing a grid of concrete-filled, steel-cased piles for the structure to sit on top of. This transfers the loads from the existing foundation to the piles.
This method involves high-pressure drilling to create columns of grouted soil under the existing structure. A temporary steel casing is pumped into the ground to a predetermined depth, followed by a grout at high pressure. Then, the casing is withdrawn. The process displaces the soil, increasing compaction and stiffness. The stiff grout columns and the existing foundation provides additional support to the structure.
Fortunately, with the services of the top underpinning Bristol, you have got nothing to worry about. Our engineers, facilitated by our experts in construction, have all the tools, experience, and skills to handle your project with the utmost expertise.
A high-tech and effective method, resin injection underpinning involves injecting a mix of resin compound and expansive polyurethane into the ground using small bore injection tubes. This results in a chemical reaction, combining the two. The compound expands and turns hard, returning the building to its original level. Resin injections are the fastest and cleanest procedure, suitable for most soil types. However, it can be costly and requires an extensive range of modern technology and tools.
