Whether the ground floor of a house is suspended or filled, it will include either a solid slab or an oversite layer of concrete laid on compacted hardcore directly on the ground. Both hardcore and soil are potential sources of sulfates and other chemicals harmful to concrete. This programme investigates the hardcore components and soil conditions likely to contain sulfates, explains how concrete is affected by sulfate attack and looks at methods used to prevent such damage.
