Q. What is the thickness of the water tank cover?

Answer

The 20 mm would be appropriate for a desert environment while the 30 mm would be more appropriate for a coastal area. The standard span for 150 mm thick RCC slab roofing on tanks is 3.5–4 meters. the depth of a slab or wall of concrete. Clearance is less than 2 inches even when the reinforcement is centered in a concrete water tank which can be as thin as 4 inches for smaller tanks. how many layers of reinforcing matting there are? Two layers of reinforcement may be used in a tank with a six-inch thick wall; again with the gap between the internal and outside bars the maximum coverage is around two inches.
