There are many different construction techniques for building a foundation. One method used by MDTI is the micropile.
What is a Micropile?
Micropiles are also called minipiles. They are elements of a building’s foundation found deep in the ground. They are made using very strong, small steel casings or threaded bars. The casing is usually 3 to 10 inches in diameter. Some micropiles extend as deep into the ground as 200 feet (though the typical micropile goes around 20) and can hold over 200 tons. They are drilled into the ground with special machinery.
The nature of a micropile is its versatility. Micropiles can be drilled through almost any kind of ground or structure, and their drilling causes minimal vibration, noise, and disturbance. The steel structure of the device allows them to hold heavier loads than other foundational components, like driven piles, augercast piling, or drilled shafts. These other deep foundation systems are unable to be drilled through many kinds of obstructions, and their drilling may disturb adjacent structures. Micropiles are the best deep foundation systems in all of these cases.
