Underpinning is a method of strengthening a building’s foundations by extending the foundations until a higher load is achieved.

Traditionally, this would have been achieved by digging out boxes under the existing foundations and pouring copious amounts of concrete to extend the foundations lower (where the soil tends to be able to withstand higher loads).

At Oly Buildings Services LTD we underpin buildings using helical mini piles, theĀ Heli Pile. We are able to install down to depths of 10 metres of more, however we rarely need to install this deep as the required loads are usually achieved at around 3 or 4 metres, depending on the make up of soil.
