Southwest Environmental has recently undertaken a site investigation in Trowbridge, Wiltshire. The purpose of the investigations were two fold.
- Find Out Soil Strengths
- Expose Existing Footings
The work was undertaken over 2 days, and the data was used to write a report on the state of the ground on site. The existing pad footing appear to be bedding directly on to the bedrock which was a cornbrash limestone: Limestone, medium- to fine-grained, predominantly bioclastic wackestone and packstone with sporadic peloids; generally and characteristically intensely bioturbated and consequently poorly bedded, although better bedded, commonly somewhat arenaceous units occur in places, particularly in the upper part. Generally bluish grey when fresh, but weathers to olive or yellowish brown. Thin argillaceous partings or interbeds of calcareous mudstone may occur.
SPT data was used to provide input data for bearing capacity calculations. These are then provided to the structural engineer.
SWEL undertake site investigation all over the UK. We try to do things on a quick turnaround where possible.
