Horizontal Direc​tional Drilling (HDD)
H.D.D. is a technique that uses a directional boring machine to steer a path underground and pull back pvc conduit or steel pipes along a predetermined bore path. This technique greatly reduces the need to dig up roads or sidewalks when installing conduit for utilities and is also good for difficult terrain.

Keystone Directional Boring LLC was established in 2014. We have over 25 years of experience drilling in all types of soils from the West Coast to Georgia and Alaska. We are based out of Roy WA.

We install  conduit for gas, power, water and telecommunication fiber up to 12”.
