Drilling for soil samples
Direct push technology facilitates better vertical profiling capabilities for generating three dimensional profiles of a site by providing undisturbed soil cores that offer a more accurate depiction of sub-surface properties.
DPP uses both macro core and dual tube sampling systems to obtain continuous soil cores or discrete soil samples from specified depths.
The Macro-Core MC5 soil sampler provides some of the most coherent, efficient and consistent samples and is suited to collecting large volumes of soil cores at shallow depths.
For most projects the dual tube system (DT-32) is more effective as it allows continuous, discrete soil sampling from a cased probe hole. This eliminates the threat of material falling into the borehole and provides maximum sample integrity as well as an accurate bore log. Sample integrity is better than obtained by hollow stem augers and direct push technology also enables such projects to be completed faster and more cost effectively.
DT-32 soil samples are contained within a 50mm diameter clear liner that can be sealed for subsequent offsite analysis or half the casing can be removed for on-site sampling and logging.
