Window Sampling Services
Windowless sampling barrels between 86mm and 116mm diameter contain plastic liners to retain soil samples. Liners are removed from sample barrels after drilling. The use of a plastic liner allows for excellent presentation of high quality samples.
In-Situ Geotechnical Testing
SPT – Standard Penetration Testing, weight of 63.5kgs is dropped over a calibrated distance of 760mm, the number of blows taken to drive the sampler over a set distance is recorded.
DPT – Dynamic Probe Testing, weight of 50kgs is dropped over a calibrated distance of 500mm, the number of blows taken to drive a sacrificial cone over a set distance is recorded.
U100/U70 – Undisturbed samples with either thin walled (class 1) or standard undisturbed sample barrels can be taken with the rig.
Boreholes can be drilled in sufficient diameter to allow 50/63mm monitoring well installations, or 19/25mm piezometer installations.
