Ground conditions represent perhaps the biggest hazard to any construction project. However, a well designed ground investigation specific to the needs of the site can reduce these geotechnical risks, and save money in the long run.
We often use the findings of desk-based studies, as well as the outline development proposals to design a suitable ground investigation employing technics specific to the anticipated geology, topography and available access.
Common methods of intrusive investigation include;
• Trial pitting (including soakaway testing in accordance with BRE 365 and percolation testing)
• Hand Pitting
• In situ tests, including California Bearing Ratio, Plate Bearing Tests and Standard Penetration tests)
• Windowless sampling
• Rotary drilling
• Cable percussive drilling
