Reasons to Consider A & H Drilling

1. Exceptional Overburden Performance: Foremost DR drills have been proven repeatedly in some of the toughest unconsolidated overburden formations, including sand, gravel, glacial till and boulders. The Dual Rotary method minimizes the likelihood of loss circulation and aquifer cross-contamination. And because the DR can drill without fluids, the ability to detect water in low flow formations is improved.
2. Straight Holes: The rotation of the casing by the lower drive results in a very straight hole. This minimizes stress on casing and casing welds and eases the task of installing screens and pumps in water well applications. It also makes the DR ideal for drilling hydraulic elevator shaft holes and foundation piles.
3. Casing Extractions: The lower drive is equally effective at pulling back casing, thereby simplifying the process of exposing a well screen or abandoning a well.
4. Control of Discharge: Cuttings are diverted through the discharge swivel and can be directed via a hose to a safe and convenient dumping and monitoring point. This is a useful feature when drilling at homeowner sites or when cutting must be contained for environmental or safety reasons.
5. Casing: We can drill 6" up to 24" cased holes and can install 24" casing up to 500' in depth depending on soil conditions.
