Mud Phuska Terracing With Tile Paving

[BGCOLOR=transparent]This method of terracing is equally suitable to hot as well as arid regions, and is commonly used over R.C.C roofing. The work is carried out in the following steps.[/BGCOLOR]

The R.C.C slab is cleared off dust and loose material. A layer of hot bitumen is spread over it at the rate of 1.70 kg of bitumen per square metre of roof surface.
A layer of coarse sand is immediately spread over the hot coat of bitumen , at the rate of 0.6 m3 of sand per 100 m3 of roof surface.

Mud-phuska is prepared from puddle clay mixed with bhusa at the rate of about 8 kg of bhusa per m3 of clay. A 10 cm thick layer of this mud-phuska is applied over the sand- bitumen layer. Proper slope (usually 1 in 40) is given in mud-phuska layer. Alternatively , slope may be given in RCC slab itself.

The mud-phuska layer is consolidated properly. It is then plastered with 13 mm coat of mud-cow-dung mortar (3:1)
Tile bricks are laid flat on plastered surface. The joints are grouted is 1:3 cement mortar.
