How do I add a slab to an existing beam?
New RCC slab can be joined with the existing one as in the following steps.
- Chip off the existing slab up to a certain depth (preferably 15 cm)
- Drill reinforcement bars into the existing slab.
- Apply a bonding agent so as to act as a bonding agent for new and old concrete.
- With the support of formwork cast the new slab.

How to extend an existing RCC slab?
Before expanding an existing RCC slab first you have to check the reinforcement ratio used in the slab, because a slab is designed on basically two parameters, The Area of steel or the steel per square foot. (As) Now for extending, design the slab and try to make a good bond between existing and new slab.
How do you insulate the edges of a foundation slab?
Exterior Edge Insulation for Existing Foundation Slabs Remove dirt to fully expose the edges of the existing slab. Clean the exposed slab edge and apply damp proofing as a capillary break. Install non-moisture-sensitive rigid foam board insulation (such as extruded polystyrene [XPS] or mineral wool)
How do you extend an existing concrete slab?
Now for extending, design the slab and try to make a good bond between existing and new slab. For a good bond, shatter some portion of concrete from the outer boundary. You can make good bond of steel by interlocking the old and new bars, and the irregular face provides good bond with old and new concrete.
What to do if there are enough re-bars in a slab?
If we find out that that there are enough re-bars we can do the following: The existing slab should be chipped out to expose the re-bars. The length of re-bars thus exposed should be at least be sufficient to develop the bond length. For every bar exposed new bars from the new slab side should be tied.
