Main information

AquaLock Piston Sampler

AquaLock benefits

  • Improved sample quality and recovery in unconsolidated alluvial soils
  • Reduce the costs per sample meter
  • Fast and accurate
  • No waste
  • No casing needed
  • Off shore sampling

Soil sampling using the patented AquaLock piston sampler collects high-quality core in a variety of conditions, even loose sand and saturated sediments typically different to collect with standard techniques.

The AquaLock is available in 3 different diameters to match your requirements. The barrels are made of stainless steel and are comprised of a valve operated drive head, internal floating piston and a choice of cutting shoes and ring bits for differing lithologic conditions. Samples can be extruded into PVC liners, polyethylene foil tube, plastic gutters or a core box.

The AquaLock is a soil sampler with absolutely unique features. The AquaLock is vibrated down directly to sampling depth where it takes a long and practically undisturbed sample. The AquaLock combines the advantages of the very rapid, smooth and powerful Sonic drilling technique with the advantages of a piston type core sampler. It can be used for continuous sampling or discrete sampling.

What can you use the AquaLock for?

  • Environmental sampling
  • Mineral sampling
  • Foundation research: You can take cost effcient and accurate samples with A3/B3 (ISO 22475-1:2006) quality to large depths.
  • Remediation drilling / well installations and cold-heat exchanging systems: In one run you can take a sample for profile description and, if required, install a well.
  • Archaeological sampling: Rapid sampling of a large area in a dense grid on archaeological remains.
  • Off-shore sampling of water bottoms: AquaLock produces long practically undisturbed cores of extremely mixed geology.
  • Pre-investigation of dewatering projects: Extremely rapid soil profiling, followed by, if required, well- installation.
