In construction projects, footings need to be set correctly on firm, non-organic soil. To set footings correctly you need soil compaction of 2,000 psi per sq inch or firmer, and not a loose organic soil. If this is not possible with the current soil then soil compaction is needed. In these cases, we must dig out the undesired material and replaced with good soil. This new soil must then be compacted and brought back up to the correct footing elevation. Soils need to be compacted to minimize settling and shifting.
Often, poor soil is discovered when the excavation begins, causing problems for both the excavation schedule and the pocket book. Unfortunately, it must be fixed properly or the new structure will fail with cracking floors and walls, and become unusable. When done properly, soil corrections can stand the test of time, providing a solid foundation for years to come.
