Harp Legacy Concrete is a partnership founded in 2005 that provides turnkey reinforced concrete foundations and basement walls for residential and small commercial buildings. They have over 60 years of combined construction and engineering experience. Their process involves excavating the site, forming and reinforcing concrete footings and walls, installing anchor bolts and waterproofing the walls before backfilling the site. Concrete foundations provide advantages over masonry including greater strength, durability, and allowance for deeper basements.
