Application

Traditional sandbags are heavy and bulky, difficult to transport and require considerable manpower to deploy often compounded by the need for fast reaction and distribution.  Because they are stored dry, they are cleaner, lighter, more effective and easier to use in the places and times when sandbags are most needed. The solution is sandless sandbag which requires no sand. Suitable for use by the emergency services, armed services, local authorities, water utilities, business and households.
