Welcome to PSL Ltd

Professional Soils Laboratory Ltd (PSL) is a fully independent 4043 UKAS accredited geotechnical and materials testing facility. PSL Ltd was established in July 2004 and is now part of Phenna Group.

Centrally based in Doncaster with a team of 50 laboratory testing and field staff, PSL is now one of the country’s leading geotechnical laboratories.

Our location gives us excellent access to the A1/M18/M1 and M62 motorways and means wherever our clients samples or in-situ testing requirements are, we can meet their expectations at their convenience.

Our flexibility and client-focused approach has opened many opportunities. We have worked on some of the nation’s most prestigious projects such as the Olympic Park and Village, as well as numerous road and rail projects.

We have an expansive client base including consultants, ground works engineers and drilling and earthworks contractors. Whether working for the small local developers or the global multi-disciplinary consultancies, we like to put the emphasis on building close working relationships with both parties being stakeholders working towards a common goal.

We work in the same way with a network of accredited partner laboratories that enables us to offer a full range of value services to the geotechnical and geo-environmental sectors.
