In recently constructed office/home accommodation in Islington, London, sandbags were used as a sound-absorbing facade adjacent to a noisy main railway line (Fig. 15.6). The sandbags, filled with a sand-cement-lime mixture and exposed to the elements, will eventually set hard. Over a further period of time, possibly 30 years, the hessian bags will disintegrate leaving the undulating concrete exposed, imprinted with the texture of the hessian fabric. The wall is experimental in that the weathering effects cannot be predicted as with other more standard forms of construction.
