| Specification Terrace Surface Method |
|
| A) |
Our treatment starts directly over the RCC slab with laying over our waterproof brick bats coba to provide necessary gradient of 1in 120. (1 inch in 10 ft) for the easy flow of rain water. Finally the bricks bat coba is covered with our joint less waterproof plaster finished smooth with trowel in cement co lour marked into 300mm (1ft.) False squares. This treatment is carried along the inner side of parapet &` or other adjoining wall up to a height of about 300mm (Ut) in the shape of a round vata.
The average thickness of this treatment is about 110 mm (4 1/2”) with a minimum thickness at water outlet points being 75 mm (3”) This surface is hard & tough, & suitable for all normal domestic activities.

| B) |
If the distance of the rain water pipes is too much or the span is more than 30 ft or 9 mts, then in this case water has to flow only on one side of the terrace and so the thickness of our treatment will increase accordingly for the easy flow of rain water.
|
| C) |
In the case of existing terraces, since our treatment applies directly over the RCC slab as stated above, the existing treatment will have to be completely removed by us, to expose the bare surface of the RCC slab
|
| D) |
If a Garden &/or a lawn is desired to be made over this treatment it is possible but with an extra charge. For this it is necessary that slab shall have a depth of 6 00 mm.(2.4”) in relation to the adjacent vertical area i.e. parapet wall &/or other side to accommodate about 150mm (6”) thickness of waterproofing 75mm (3”) thickness for |
