Hand Dug Trial Pits

 

Trial pitting can be carried out with the use of insulated hand tools, for many different applications.

ADP Group have hand pitted for monitoring well installations, soil sampling, foundation inspection, utility clearance, soak-away testing and buried structure investigation; to name but a few!

Where the application is not for soil sampling, ADP Group would always recommend vacuum excavation for trial pitting; for the safety it brings to both operator and buried apparatus.

Machine Dug Trial Pits

 

ADP Group can provide trial pitting via both tracked and wheeled excavators, to depths in excess of 4m.

ADP Group can supply either tracked 360 or wheeled 180 excavators, with or without hard-standing breakers.

All ADP Group machine operators are either CPCS or NPORS qualified, and all machinery complies with PUWER.

California Bearing Ration (CBR)

 

The California bearing ratio (CBR) is a penetration test for evaluation of the mechanical strength of road sub-grades and base-courses. It was developed by the California Department of Transportation before World War II!

ADP Group’s experienced and competent engineers, can provide CBR testing on any site in the UK, with the use of our Land Rover mounted, testing rig.
