Drilling is our “wHOLE Business”. Western Foundations & Shoring offers a wide variety of drilled caisson shaft types, dimensions and depths. We perform standard large diameter drilled shafts from 12 inches diameter up to 8 feet diameter. We have small limited access drill rigs that are 40 inches wide that can drill 30″ diameter x 50′ deep and large drill rigs that can drill as deep as 200 feet. Need a hole drilled?
