Excavation support is a large part of what we do at H.B. Fleming, and we have the expertise and the equipment to install a broad range of structures. Each project has specific challenges with respect to excavation depth, water elevation, surcharge loads, working room for other trades, existing utilities, etc. Our in-house design staff are quick to deal with problems as soon as they arise to keep projects running.
