Trial Pits for Flintshire County Council

A trial pit is an excavation of ground in order to study or sample the composition and structure of the subsurface. Trial pits are usually between 1 and 4 metres deep, and are dug either by hand or using a mechanical digger.

We undertook a series of trial pits on behalf of Flintshire County Council to expose the size and depth of the existing foundation to a series of store cupboard annexes at a number of residences, all of which were suffering from subsidence. The Surveys, carried out in conjunction with Salem Myer Simpson, confirmed that Helical micro piles would provide the required structural support to the foundations and alleviate the current concerns/issues. Based upon the results of the survey SUKR & Helifix were then able to provide a full design and specification for Flintshire County Council.
