About Spartan Directional

SPARTAN DIRECTIONAL, LLC under the direction of Boyd Simon, P.E. and Barry Nailling and others, is a horizontal directional drilling (HDD) company specializing in large pipe diameter sizes and extended crossings.

The niche of Spartan’s experience in horizontal directional drilling has proven to be the key to our success in overseeing drills for large diameter pipe sizes and extended crossings. Our team of employees are record holders in the HDD industry, having completed a horizontal directional bore of 11,065 feet, via an intersect, across the Texas/Louisiana border under the Sabine River and associated wetlands.

Spartan recently completed the longest-largest diameter HDD in North America with a 2,993’ drill of 54-inch pipe underneath downtown Miami Beach. The combination of our equipment, in addition to the talent assembled at Spartan Directional, LLC allows us to oversee and execute multiple large projects simultaneously.
