Foundation design and associated recommendations for projects ranging from simple residential extensions to large industrial units on greenfield, previously used or reclaimed former brownfield/quarry sites specifically tailored to the individual requirements of the site based on ground and groundwater conditions, level of data collection required and budgetary constraints.

TSL provide:

• Bespoke software to improve accuracy and efficiency for design of shallow foundation options and deeper foundation parameters using specialist contractors

• Preferred specialists academics for complex design and assessment

• Excavation and basement design

• Liaison with building control services provided by Local Authorities, NHBC or other Insurers

The typical geotechnical appraisal report for the site includes:

• Soil profile (borehole logs/dynamic probes/CPT’s)

• Soil classification testing

• Shear strength and moisture content versus depth profiles

• Consolidation characteristics

• Assessment of volume change potential of fine grained soils – favoured by NHBC on residential developments

• Recommendations on type and depth of foundations

• Recommendations on the type of cement to use in buried foundation concrete

• Recommendations for excavation for foundations, services and drainage

• Floor slab design

• Soakaway design

The geotechnical appraisal can also be combined with a site contamination assessment where deemed necessary in a cost effective manner.
