01

Geotechnical subsoil investigation

Understand the ground before you build. Surface and subsurface investigations provide the information needed for engineering design and safe construction.

Our investigation methods include Dutch cone penetration testing with 2.5-ton and 10-ton equipment, and boring with Standard Penetration Tests (SPT) using Dando 2000 and Dando 3000 equipment on land and water.

Pile foundation installation

Transfer structural loads through weak soils to a stable underlying stratum, with deep foundations for developments on land and water.

The company profile documents cable rotary, hydraulic, percussion bored-cased and Continuous Flight Auger (CFA) piling methods, together with concrete placement using tremie pipes.

03

Ground improvement

Improve the strength of granular soils through vibroflotation, using vibration to densify loose deposits and reduce pore spaces.

An electrically powered hydraulic probe is deployed into the subsoil to rearrange loosely deposited soil grains. This ground improvement method is particularly useful for granular soils.

04

Quality assurance

Assess completed foundations and concrete structures through pile integrity testing, pile load testing and non-destructive testing.

Pile Integrity Tests (PIT) assess the continuity and condition of installed piles. Pile Load Tests (PLT) verify load performance against the design. Non-Destructive Testing (NDT) assesses concrete without damaging the structure.

Project management

Coordinate the professionals, programme and project constraints needed for efficient, cost-conscious delivery.

Our project managers work with professionals across the construction industry, coordinating delivery on behalf of clients with a focus on quality, communication and effective use of resources.

Construction works

Continue from installed piles into the substructure, including pile caps, ground beams and ground-floor slabs.

We provide continued construction services on projects where we are commissioned to install piles, helping clients progress from their deep foundations into the next stage of construction.
