Reinforced concrete piers

Ordinary concrete has been employed for very many years in the construction of piers, dock and harbour works, and reinforced concrete has been similarly used for nearly a quarter of a century in this country. During that period some 350 maritime and kindred structures are said to have been completed on the Mouchel-Hennebique system alone, and if similar statistics were available as to the works executed in accordance with other systems of reinforced concrete, the number mentioned would be very largely increased.
