Professional Soils Laboratory
Professional Soils Laboratory Ltd is a fully independent UKAS accredited geotechnical
and materials testing facility which was established in July 2004, previously being part of
a well known construction company Thyssen GB Ltd.
CentrallybasedinDoncasterwithateamofalmost40laboratoryandfieldstaffPSLhas
quickly become one of the countries leading geotechnical laboratories.
Our location gives us excellent access to the A1 / M18 / M1 and M62 motorways and
means wherever our clients samples or insitu testing requirements are we are able to
meet their expectations at their convenience.
Ourflexibilityandclientfocusedapproachhasopenedupmanyopportunitiesand
allowed us to work on some of the nations 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 and 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.

As well as the routine testing we also specialise in the testing of soils for ground
improvement techniques such as lime and cement stabilisation as well as swelling /
heave and soil suction testing for the subsidence claims industry.
All our reports are supplied by email and we are able to report AGS data when required.
