Micropiles & Minipiles

First developed in the 50′s, micropiles (or minipiles) were able to help repair the foundations of old historic structures, where there was not a great deal of head room for the installation of conventional pile systems. Today, micropiles are some of the most widely used deep foundation repair elements.

Micropiles are used in a specific process called “underpinning,” which reinforces or stabilizes an already existing structure. Although there are several different types of micropiles, generally, they are high-capacity, small-diameter (60 to 200 mm) steel casings that are drilled into position, reinforced with an internal structural bar, and finally, pressure grouted. This grout bonds the interior casing wall and structural bar together – and it also bonds the soil with the external casing wall.

Versatile to any ground condition, we believe that micropiles are an economically feasible, yet extremely effective method of foundation repair in Atlanta, and virtually everywhere else for that matter. Whether a structure is tall and thin, or simply aged, Extreme Technology’s Atlanta micropile contractors have nearly 15 years of experience using various micropile and minipile systems to meet the foundational needs of structures, large and small.
