Phase 2 Geotechnical
Site Investigation

Divider Green

We carry out a phase 2 geotechnical site investigation to obtain information on the physical properties of soil and rock on your site.

Our team of geotechnical experts delivers practical solutions; geotechnical site investigation, slope stability assessments, land drilling, in-situ testing and basement impact assessments, that will see you through the feasibility, cost planning and construction phases of your project.


Why do I need a phase 2 geotechnical site investigation?

A phase 2 geotechnical site investigation will provide in-depth information on the ground conditions on your site. This allows for a geotechnical appraisal, design and advice, for foundations, earthworks and other geotechnical solutions. It typically involves the advancing of exploratory holes such as boreholes and trial pits to obtain disturbed and undisturbed soil samples for laboratory testing.

Why use us?

  • Established over 20 years
  • One-stop multidisciplinary
  • In-house land drilling with rigs
  • Collection of technical experts
  • Ex-local authority regulators in our team


Our phase 2 geotechnical site investigation can consist of one or more of the following:

Land drilling

We can determine the best locations for the intrusive investigations and will use our in-house drilling company to undertake the work alongside our experience geo-environmental engineers.

The intrusive investigation can range from all-terrain and handheld window sampling, rotary drilling, concrete coring, cable percussive, foundation pits and soakaway testing. The techniques used depends on what the development of the land/site will be being used for in the future, and the appropriate depths you would like the samples to be taken from.

Soil testing

Representative disturbed and undisturbed samples collected from the site investigation are forwarded onto a UKAS accredited laboratory for geotechnical testing, such as classification, strength and consolidation tests. The results are then used to inform the geotechnical design of the project.

Groundwater monitoring

Groundwater monitoring typically comprises the measurement of water levels and the recovery of water samples for laboratory analysis. 

In-situ testing

Our in-situ testing provides high-quality data for the behaviour of soil and rock, under well-controlled stress conditions. This will determine whether the ground conditions are suitable for your developments.

What our clients say

“In essence, it can be difficult to find a value-driven consultancy. Especially one that’s capable of offering meaningful and pragmatic advice at short notice. The LK Group, in contrast, never disappoints. In fact, they tailor their services to a wide range of site-specific challenges on my sites and then get on with it. Their approach, above all, is always straightforward.”
