Test Pit Excavation Services
Safe & Reliable Test Pit Excavation for Geotechnical, Environmental & Utility Investigations
Hanlon Drilling provides professional test pit excavation services to support geotechnical investigations, environmental assessments, utility locating, and construction planning. Using the appropriate excavation equipment for each project, our experienced team exposes subsurface conditions quickly and safely, giving engineers, geologists, and contractors direct access to soil profiles, underground utilities, and buried structures.
Test pits offer a practical and cost-effective method for evaluating shallow subsurface conditions, allowing for visual inspection and sampling that cannot always be achieved through traditional drilling methods.
What Are Test Pits?
A test pit is a shallow excavation created to expose and examine subsurface soil, rock, utilities, or existing infrastructure. Unlike drilled borings, test pits provide a full view of the soil profile, enabling engineers and environmental professionals to observe soil layering, identify buried materials, verify utility locations, and collect representative bulk samples.
Test pits are commonly excavated using excavators or backhoes and are typically restored after the investigation is complete in accordance with project requirements.
