Soilbags are usually incorporated into temporary structures, rather than being used in conventional construction, as they have a tendency to deteriorate rapidly on prolonged exposure to sunlight. The amazing bearing capacity of soilbags has, however, inspired the development of an earth reinforcement method in which the bearing capacity of soft foundations is enhanced, reaching ten per cent of that of concrete. New methods have seen their projected durability as a semi-permanent material extend to in excess of fifty years, provided that direct exposure to sunlight and ultra-violet rays is...
