Underpinning

Commercial + Residential

EDSON Deep Foundations - Your trusted company for underpinning in South Florida.

When a foundation must be strengthened—due to failure of original piles, adjacent excavation, or a change in supporting soil—underpinning is used to strengthen and stabilize the structure. In some cases, the building will be used for a new purpose, which also requires addressing foundation issues.
Underpinning typically extends the foundation in breadth or depth—or both.

Installation

A construction strategy for underpinning foundations depends on the specific project site, soil, structure and existing foundation materials and condition. Underpinning usually requires either machine or hand-dug excavation work, multiple support techniques, and pin pile or micro pile solutions.
