I'm extending the garage at my house and need to add a meter wide strip of new concrete to join the existing slab floor. The existing slab was poured in 1968 and hasn't moved an inch.... im not removing it all just to put it all back in.
Whats the best way to add to it and how is it best to achieve it. One way I considered was digging under it slightly to form a shelf underneath and when the new concrete is added, it will flow under it and the existing concrete slab will rest on the new bit.
The other thought I had was hammering lengths of rebar into the joining face of the existing co create not sure what the procedure is.... I.e. to chem fix em or just hammer into appropriately sized holes with no resin.
