Understand The Ground. Plan With Confidence.

Before construction or development begins, it can be important to understand what lies beneath the surface. Trial pits allow specific areas of ground to be exposed for closer examination, helping to establish information about the soil, buried materials and existing site conditions.

Where archaeological interest is a consideration, ground investigation may also form part of the process of examining a site and identifying features that could affect the proposed works. The investigation required will depend on the site, its history and the objectives of the project.

Every site has its own requirements. Understanding the purpose of the investigation, the location of the work and any relevant site constraints helps establish the appropriate next steps before work gets underway.

Ground Investigation

A Closer Look Beneath The Surface

Trial pitting can help reveal ground conditions that may not be visible from the surface. By exposing selected areas of ground, the investigation team can examine the materials encountered and gather information relevant to the proposed works. The approach depends on the purpose of the investigation, the nature of the site and any archaeological or other constraints that need to be considered before excavation begins.

Look Beneath. Understand More.

Ground investigation helps project teams understand what lies beneath a site before decisions are made about future works. Trial pits can expose ground materials and features for examination, with the investigation planned around the needs and constraints of the individual project.

Our Approach

Investigate. Understand. Plan Ahead.

Every site presents its own ground conditions, constraints and project requirements. A considered approach to trial pitting and ground investigation helps establish what needs to be examined before the next stage of work can be planned.

01 / UNDERSTAND

Understand the site

Start by establishing the purpose of the investigation, the site conditions and the information the project team needs. Access, existing structures and any known constraints should be considered before excavation begins.

02 / INVESTIGATE

Examine beneath the surface

Trial pits can expose selected areas of ground for closer examination of soil, buried materials and visible features. The location and extent of excavation should reflect the investigation brief and the conditions on site.

03 / PLAN AHEAD

Move forward with clarity

The findings and site requirements can help inform decisions about the next stage of a project. Where archaeological investigation or specialist assessment is required, the appropriate expertise should be involved.
