Excerpt from Construction of La Corbière Lighthouse and the St. Helier's Harbour: Built in Concrete at JerseyThere appear to be two reasons why but little attention has hitherto been paid to this art, first, carelessness or indifference to appearance, secondly, that most of those who have attempted it have done so by rendering with plaster or by grouting with liquid mortar, both objectionable and dangerous modes of effecting the object. These are at the best only a veneering liable to sudden decay, and the failure (generally occurring after wet and frosty weather) has naturally stopped a repetition of the attempt.The plan which the Author has followed in harbour walls, both above and below low water, exposed to frost, heat, storm and rain, with complete success and at an in appreciable increase of cost, is to have a smooth planed board for the face of the mould, painted over previous to commencing the work with a mucilage of soap to prevent the mortar adhering. In filling the frame, care must be taken that a finer mixture of concrete or coarse cement mortar be laid in with a trowel close to the face board, as the Work proceeds, so that the mixture is carried up uniformly with that contained in the body of the work, the whole forming one homogeneous mass, and ensuring the setting process of the whole mass being carried out simultaneously, so that the face is, in fact, like the skin of an iron casting, and actually the strongest portion of the mass. It is intended, in this Paper. To give a description of the construction of the Corbiere lighthouse, which the Author believes to be the first of the kind in the British Islands made of Portland cement concrete. It was erected by him as executive engineer for the States of Jersey, from the design of Sir John Coode, M. Inst.
