Soil & Ground Investigation
At Streval we have a great amount of experience of working with structural engineers to help our clients understand or analyse the ground in order to confirm whether changes to the loading of the ground bearing slab can be undertaken safely. To do this we can carry out plate load testing, California bearing ratio testing (CBRs), Shear Vanes or Dynamic Cone Penetrometer.

DCP Testing
The DCP uses a 6.8 kg steel mass falling 50.8 cm that strikes the anvil to cause penetration of a 3.8 cm diameter cone (45° vertex angle) that has been seated in the bottom of a hand augered hole.

Plate Load
Plate load test is a field test, which is performed to determine the ultimate bearing capacity of soil and the probable settlement under a given load.

Ground Bearing
We receive many enquiries for projects where the ground bearing capacity of a slab needs evaluating due to refurbishment or changes to the structure and loading profile on the ground bearing slab.
