Drilling

Foundex’s drilling services include rotary‑based methods such as mud rotary, air rotary, dual rotary, reverse circulation (air), and reverse flood (mud or water), as well as specialized drilling methodologies including Sonic drilling, Becker hammer drilling, and wireline coring. These services are applied across a wide range of site conditions, from shallow investigations to deep or unstable formations, and are supported by flexible equipment configurations and experienced field crews.

Foundex’s drilling systems can be configured to support a broad range of sampling and in‑situ testing methods performed within drilled boreholes, including:

• Standard Penetration Test (SPT) sampling
• Large‑diameter penetration testing (LPT), used where conventional SPT methods may not be representative or practical in coarse‑grained soils
• Shelby tube sampling, including push‑type and piston‑type methods, for recovery of relatively undisturbed samples in cohesive soils
• In‑situ vane shear testing
• Packer testing systems
• Pressuremeter testing (PMT)
• Cone Penetration Test (CPT) tooling
• Specialized project‑specific sampling equipment

With adaptable equipment, decades of field experience, and the ability to integrate multiple drilling methods within a single program, Foundex delivers drilling services that support safe, efficient, and dependable investigation programs across a wide range of site conditions.
