Test Borings

Drilling Methodologies

Our drill rigs are equipped with both rotary auger head and direct push hammer capabilities, which enable us to perform a variety of explorations. The type of boring and sampling methods chosen for a project are often determined by the site conditions, scope, and budget.

Test borings are performed to obtain a subsurface profile by allowing for visual classification of soils through sampling. Soil parameters are obtained through various in-situ testing methods which can be used in conjunction with different types of borings.

Sampling & In-Situ Testing Methods

Standard Penetration Test SPT (Auto-Hammer) 
Thin Walled Tube Sampling (Shelby Tube) 
Field Vane Shear Test (ASTM D2573)
Groundwater Monitoring Wells (1 inch or 2 inch PVC) (ASTM D5092)
​Gravel Punch Sampling (3-1/2 inch surface sample)
Direct Push Soil Liner Sampling (2-3/4 inch or 1-1/2 inch at 5 ft length)

Hollow Stem Auger Boring for Soil Exploration (ASTM D6151)
Rock Core Drilling and Sampling (ASTM D2113)
Cone Penetration Testing CPTu (ASTM D5778)
Downhole Seismic Testing ASTM (D7400)​
