A structural component consists of a concrete core 601 and an outer skin of fibreglass. The concrete may comprise cement, sand, gravel, expanded clay, micro silica, fly ash and/or non-metal reinforcement elements 602. A layer of aggregate may be provided between the concrete core and the outer skin of fibreglass. Ideally the concrete is poured into the skin after the resin of the fibreglass has cured and hardened. The structural component could be provided with holes 802-805, to be used as a memorial stone.
