                                     Soil Sampling

Team EFS utilizes two basic soil sampling methods; Continuous Core and Discrete Soil Sampling. Both have multiple tooling systems which have advantages depending on the site characteristics and your actual scope of work. All systems operate with both our Truck or Track Geoprobe's.

Macro Core

 

Closed Piston

Dual Tube

Large Bore

Manual

General use 0-25"bgs, sample to ~5' below GW, normal

soil conditions

Sample below GW, expanding clays, loose sand/gravel

Deep sampling >25' bgs, caving sands, below GW, discrete sampling

Discrete sampling at greater depths, 25' - 75' bgs

Use large bore, driven with rotary hammer drill, shallow
