Undisturbed sampling

We manufacture different product lines for soils sampling, including the new Eurocode 7 system. The new thin wall sampling system obtains undisturbed samples through a thin wall tube that is contained in a steel tube, which is extruded in a laboratory. We manufacture UT100 tubes in steel or aluminium material, cutting shoes, catcher baskets and any crossovers. We maintain regular stocks of the products for immediate despatch. We also supply any item in a variety of material treatments for hardness to rustproofing requirements.

Drilling Supplies UK stocks and supplies the original U100 sampling products. Product lines are used with plastic liners but also steel tubes and all shoes, baskets and heads. To help obtain undisturbed samples, we produce a heavy-duty sliding hammer complete with API threads, enabling us to offer a more complete package.

Standard penetration test (SPT) drop hammers are also manufactured in-house and are used to obtain an SPT sample to conform to British Standards. These have a drop of 760 mm with a drop weight of 63.5 kg and come complete with a calibration certificate. We can also repair old hammers and generate a new calibration certificate as required every 12 months.
