Environmental Sampling / Concrete Coring
Our tracked ‘Terrier’ drive sampling rig can take lined core samples up to depths of around 14m. Drilling progresses in 1m stages and produces a 1m long sample, held within a sealed plastic liner. SPTs are / can be carried out between sample runs to ascertain ground strength properties.
Holes can be simultaneously cased and sampled preventing cross contamination of samples and this allows the for the easy installation of any ground water or gas monitoring equipment such a piezometers
The terrier is also able to separate the mast from the tracked power unit allowing work to continue in places that would have otherwise been impractical or unreachable. This is made possible by using extra long hydraulic hoses that mean the power unit can remain outside whilst work continues inside unrestricted by the potential for fumes.
