Why Do Michigan Soils Cause Foundation Settlement and How Can I Address This Problem

Deep foundation piers are useful in most areas of Michigan. But there is no soil that are not completely stable? A temporary one can say yes. But Michigan clay soil so varied and each type can take on so many consistencies that every site requires a special test and / or evaluation.

Michigan deeper soil levels are influenced by its history. During the ice age, ice-soil land rock flows in different categories and push them around. Topography with numerous lakes and rolling hills and sand dunes with little land left. Rain, weather, and soil and vegetation were ideal for tree growth. As years passed, trees and vegetation turned into organic soil. Lakes, swamps, lowlands filled, and the wet ground made unique characteristics. Stream flood sediments laid down and took clay.

At the same time, shifting sand dunes, Lake Michigan are standing. Between these extremes of rolling hills, forests, agricultural lands, and so on.

Sand resulting from the different features for each type of soil and clay loam soil to dung: hard to soft, dense, well graded loosely classified poor. Loose and soft soil foundations do not support well. Stable soil water that can leverage and basement walls Hold push. Grade structure opposite the water can run. This means that every site specific characteristics and remediation requirements might be infinite.

With the soil to such a wide array of challenges to address the capacity of a steel deep foundation is one of the greatest benefits. The term "steel foundation" or "deep foundation," especially with pre-construction or helical piers and foundation repair underpinning push shows. These piers were designed for great flexibility to the soil, loading requirements, and provide access challenges. They're free vibration, these piers installation does not damage neighboring structures. They quickly are set to use easy to calculate the capacity to prepare for, and often, the only rational answer in a compromising position.

A particular type of soil condition in this type of pier is effective. For these "helical" piers or piles are sometimes referred to as "screw", and an existing structure need not resist. They can be installed directly into the soil, as they one or more helix-shaped "flights" are drawn with (metal plate) is a steel shaft welded. Allows the installation rather than using torque resistance. These piers are necessary pre-construction applications, and sometimes preferred in foundation repair. On the other hand, "push" piers hydraulically operated are as break resistance using an existing framework. Either type of pier is effectively optimal installation or pins to repair a foundation.
