Window Sampling Services
Window/Windowless Sampling
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.
Well Installation
Boreholes can be drilled in sufficient diameter to allow 50/63mm monitoring well installations, or 19/25mm piezometer installations.
