Video: DT325 Driven Casing SPT (OTE) Overview

Employing direct push methods to collect split spoon samples minimizes job site debris while expediting production. Using DT325 sampling system rather than augers minimizes weight maneuvered by drill crew and can keep tooling to the confines of a rod rack.

Advantages of OTE Split Spoon Samples

• lightweight
• fast
• provides a continuous sample
• does not require drilling fluid

Split tube soil sampling system manufactured under U.S. Patent 9,551,188. It is best practice to consult applicable ASTM standards when performing geotechnical investigations.

Using the 3.25 OTE system was lighter to carry, productive, and easy to work with. The 3.25 rods are lighter to pick up than augers- so it's easier on the guys doing long days of geotechnical sampling.
