Deep Foundation Solutions

Deep Foundation services transfer structural loads through to competent soils or rock when shallow foundations are not feasible due to weak, compressible soils near ground surface. Micropiles, Helical Piers and Underpinning, driven piles, and pulldown micropiles are deep foundation elements. MDTI has experience with a full range of deep foundation techniques and products to provide the most cost-efficient and technically appropriate solution for any deep foundation project.


Micropiles (also referred to as Mini-Piles) are deep foundation, small diameter grouted piles typically consisting of a central steel reinforcement member and commonly includes steel casing. MDTI offers a variety of products for micropile system installation, including Magnacore SDA’s, Atlas Copco Hollow Bar, and Chance Anchors. Learn more about Micropiles here.

Helical Pulldown Micropile

The Helical Pulldown Micropile from MDTI is a system for constructing a grout column around the shaft of a standard Helical Pile Foundation System. The Helical Pulldown Micropile does not require removing spoils from the site. By combining both end-bearing on the helical plates and skin friction along the rough surface of the grout column, the result is a higher capacity pile system.
