Underpinning

Underpinning is the process of strengthening and stabilising the foundation of a building or structure and at Performance Foundations our teams are well trained and widely experienced in this construction technique.

Underpinning involves extending the foundation so that it rests on a more supportive soil stratum or distributes its load across a greater area, and it may be necessary for a variety of reasons:

• The original foundation is not strong or stable
• The use of the building has changed
• The properties within the soil supporting the foundation have changed (e.g. through subsidence)
• The construction of nearby structures means that excavating the soil supporting the existing foundations is needed
• It is may be more economical to improve the buildings current foundation than to build a new one

The vast bulk of underpinning projects involve partial works only. Total underpinning may be performed when an entire building is found to be settling, perhaps on soft ground or made ground, or when an additional storey is to be added to a building.

Traditional underpinning works have been carried out for many years by Performance Foundations and include pad and beam pin piling and grouting.
