Seattle Drilling Equipment
Presently owning and operating one of the largest drilling equipment fleets based in the Northwest

We maintain an inventory of steel casing, timber lagging, and other construction products in order to react timely to emergency situations.

Our Founder, Donald Morin, has been in the drilling business since 1955 and our Owner/President, David Morin, since 1978. All of our operators/superintendents have 10 to 30+ years experience in the business. Resumes are available for all parties upon request.

We work closely with both geotechnical and structural engineers to help provide an accurate and realistic bid, based on your design. We can also provide free site visits and analysis of your project requirements.

We are interested in all forms of drilling-related construction, including but not limited to: excavation support systems, soldier pile retaining walls, landslide stabilization, shotcrete retaining walls, soil nail and tieback walls, secant walls, elevator jackshafts, underpinning and deep foundations for towers, transmission line foundations, pole structures and caissons.

We specialize in difficult access situations and have the equipment and experience to drill almost any shaft. 

We offer a rental service if it is determined to be in your best interest.

Should you wish to expand the scope of work, we have an experienced team capable of meeting the task. For example: concrete slabs, precast concrete panels, grade beams, walls, excavation, roads, etc. While we do not actively seek this work to avoid being in competition with your needs, we do offer this service if requested.

It is our goal at DMI to construct your project as described in our proposal and for the price you have been quoted.
