Reliable contractor for underpinning in Dorset

Underpinning in Dorset and beyond involves strengthening the foundations of an existing structure, whether that’s a residential property, a commercial premises or other structure. The work usually involves deepening the existing foundation or taking steps to distribute the building’s load across a wider area. It’s a major project, but with the right team on board, it can be done safely and efficiently, strengthening the structure for many years to come.

When Might Underpinning Be Required?

In many instances, underpinning is the way to tackle issues related to subsidence. There are a number of reasons why this might be necessary. Perhaps the original foundations were not constructed properly, or the type of soil on which the property was built was not taken into account when the building was first erected. Soil conditions beneath the existing foundations could have changed over time.

Another factor might be if neighbouring structures have subsequently been built, renovated or excavated, and this has affected your property’s foundations. And finally, if you are adding a basement to your home or business premises, underpinning might be needed to reinforce the existing foundations.

“Congratulations on two members of your team; Anthony and Simon. They are brilliant workers, extremely polite and they are a credit to you! On their departure, they left the site very clean and tidy.”

René and Margaret

“Extremely professional in both their approach and execution of what can only be described as a difficult job. It is so important to get the foundations right and Tri Court certainly did that.”

Stephen Ehrhart

“Tri court couldn't have been more helpful. They did our piling including ring beam and steel re-bars and cages. They were in and out nice and quickly and worked really hard. Did a great job. I have recommended them several times since. Took the stress out of a stressful time.”


“Simon and Anthony were complete professionals and did a high quality job. They kept me informed on what needed doing and how they were progressing. Big shout out to Simon who dealt with a water leak on day 1 on an unknown pipe and getting very wet in the process. Tri Court are top professionals.”
