Our History

Bachy Soletanche is the UK subsidiary of the Soletanche Bachy Group, the world’s largest specialist geotechnical contractor with a turnover in excess of £1 billion. Soletanche Bachy has over 10,000 employees based in 31 countries. Bachy Soletanche conducts projects in the UK, Ireland and Northern Europe.

Both Bachy and Soletanche were founded in France during 1922 and 1931 respectively. Although less diverse, Bachy focused solely on construction drilling and site investigation works, whilst Soletanche specialised in complex dam water – leak sealing techniques. Innovative design in both product and application technique saw both companies develop into strong corporate organisations.

In 1997 the two French parent companies merged to create the largest geotechnical construction company in the world, employing over 4,000 employees worldwide, in 70 offices.

The United Kingdom subsidiary company of Bachy was established in 1986, upon the acquisition of Pigott Foundations Limited, and Foundation Engineering Limited. Together with Soletanche, the combined attributes of each company have brought a diverse range of innovative, resourceful design and quality construction to the market.
