Welcome to Frontier-Kemper Constructors, Inc.

Frontier-Kemper has performed more large-diameter raise-boring work than any other contractor in the US. For many mine development applications, raise-boring offers time and cost saving benefits over conventional drill and shoot development methods. Raise Boring can result in faster advance rates, less disturbance of the surrounding rock, and added safety.
