Slab Foundation Repair

Franklin is situated in an area dominated by heavy montmorillonite and illite clay formations overlying fractured limestone bedrock. During wet winter and spring months, these soils absorb immense volumes of water, expanding and exerting strong upward heaving forces. Conversely, extended summer dry spells leach moisture from the soil, causing it to shrink dramatically and pull away from footing perimeters. This cyclical soil movement results in differential settlement, wherein one corner or section of a concrete slab sinks at an accelerated rate compared to the rest of the structure. Mechanical underpinning via bedrock-anchored steel piers is the only proven method to permanently bypass these unstable soil layers.
