Summit Line Construction identified the need to implement a “Drilling Services Division”. This allows our clients added flexibility in their projects. We currently have (5) drills that have the proven ability to successfully drill and place caisson’s up to 12’ diameter x 80’ deep. Our project history shows the ability to drill through various soils and rock. Our lo-drills allow us the ability to drill with low over-head clearances and in rough terrain thus proving to be a savings for our clients. We are currently licensed and have the ability to use explosives as needed with our drilling; our clients benefit from the ability of a contractor to directly provide all needed services in house from one contractor.

Summit Line Construction is committed to stay on top of industry standards for all drilling requirements and continues to invest in training of employees and leading edge equipment to allow an on time professional product for our customers.
