Whether it’s a single-family home basement, or a large commercial foundation, Bougalis has the experience and equipment to handle basement excavation with confidence. This includes excavating to required depth, properly preparing footing trenches, managing groundwater or soils, coordinating with foundation formwork and concrete pouring, installing drainage / sump systems as needed, and safely backfilling once foundation work is done. We understand the local geology, winter frost depths, and structural requirements that ensure your basement is dry, stable, and long-lasting.
