WATERPROOFING TREATMENT FOR THE ROOFS OF MULTI-STOREYED BUILDINGS

Waterproofing Treatment Of Concrete:

Waterproofing treatment of concrete is an essential part of building construction. In case of multi-storey building, besides waterproofing, thermal insulation is an equally important factor to be kept in view. This is achieved by increasing the thickness of the grading by using economical and effective materials. The water-proofing treatment generally given to roof of multi-storey buildings and other important structures may be divided into the followings steps:

1. Painting the top of roof slab uniformly with a layer of hot bitumen spread at the rate of 1.70 of bitumen per sq.m of the roof surface.


2. Spreading immediately coarse sand at the rate of 0.6 cu.m of sand per 100 sq.m of roof surface when the bitumen is still hot.

3. Laying cinder concrete 1:15 (1 cement:15 cinders of 13 mm and down gauge) in an average thickness of 15 cm, the slope for the proper drainage of the roof being given to this layer.

4. Laying 7.6 cm thick layer of lime concrete over the consolidated layer of cinder concrete, the lime concrete being prepared bu mixing 50% of mortar consisting of lime and sand mixed in the ratio of 1:2 with brick ballast 25 mm, and down gauge.

5. Spreading 13 mm. a thick layer of cement mortar 1:3 and laying tile brick flat and open jointed over the mortar. Finally grouting the joints in the bricks with cement mortar 1:3.
