Firstly, if you intend extending the existing roof slab,follow the underlisted procedurs:
1. Ensure that, at least 600mm exposure of the existing slab reinforcement achieved.
2. Prepared the formwork for the proposed new slab with adequate proping.
3. Prepare and fixed designed reinforcement for the new slab,ensuring adequate overlapping with the existing exposed bars.
4. Prepared and placed Insitu concrete,following the designed mixing ratio or grade.
5. Allow for proper curring before removing the formwork.

proper overlaping i.e; 50*diameter of the reinforcement bar and the same time use the NITO BOND chemical for adhesive purpose and proper skilled labour
