he low-cost, thin-shell, ferrocement cover was developed as a response to the perceived need for a cover that uses no shuttering, uses little material and can be made remote from the tank and lifted into place once the tank is complete. The cover uses a reciprocal steel frame (6 and 10mm rebar) which is covered with chicken mesh and then rendered with a cement render.
