Rotary Wash Drilling Services
Precision Rotary Wash Drilling for Environmental, Geotechnical & Water Resource Investigations
Hanlon Drilling provides professional rotary wash drilling services for projects requiring reliable subsurface exploration in a wide range of soil conditions. Our experienced drilling crews utilize advanced rotary wash drilling techniques to obtain high-quality soil samples, install monitoring wells, and support environmental and geotechnical investigations with precision and efficiency.
Rotary wash drilling is a versatile method that allows drilling through unconsolidated soils and select rock formations while maintaining borehole stability, making it an excellent choice for complex site investigations.
What Is Rotary Wash Drilling?
Rotary wash drilling is a drilling method that uses a rotating drill bit and circulating water or drilling fluid to loosen and remove soil cuttings from the borehole. The drilling fluid carries cuttings to the surface while helping stabilize the borehole during drilling.
This technique is commonly used when deeper borings are required or when subsurface conditions make auger drilling less effective. Rotary wash drilling can also be paired with a variety of sampling methods to obtain representative soil data for engineering and environmental analysis.
