Can we join two slabs?
Newly laid RCC slab can be jointed with the existing slab by providing a suitable construction joint. Easiest way is the taper the edge of the slab at 45 deg backwards.

How do you attach concrete to existing concrete?

How do I join old slab to new slab?
We should not join the new slab with an old slab only with the help of a cement slurry. Clean the joining surface of the old slab with the help of a metallic brush completely. Overlapping of reinforcement should be done. The joining portion of the slab should be sloped (45 Degree).
Can you pour a concrete slab on top of another slab?
Yes, you may pour a concrete pad overlay over an existing slab. You need to consider the added height and weight of the overlay on the existing structure. Overlays may include polymers, portland cement concrete, or epoxies.
Can I pour concrete on top of old concrete?
You can put new concrete over old concrete. However, unresolved issues with your old concrete, such as cracks or frost heaves, will carry over to your new concrete if not taken care of. In addition, you must pour it at least 2 inches thick.
What is the best concrete expansion joint material?
Silicone provides an excellent alternative to the three expansion joint fillers above, and for a few reasons. First and foremost, it is flexible and durable, allowing it to accommodate the natural expansion and contraction of the slab without cracking or breaking its seal.

Construction Pro Tips
A Good Base Is Everything!
Concrete will crack and crumble if it’s not poured over a solid, stable base. Bringing in 4 to 6-in. of a good compact-able base is a good rule of thumb, but the exact amount of base a concrete driveway needs depends on the condition of the existing soil, the climate, and what you plan to park on your driveway.
You may be able to pour directly over sandy or gravelly soil without bringing in any additional base. But if you live in a cold climate, are pouring over heavy clay or organic soil, or plan to park heavy vehicles on the driveway, you may want to increase the base layer to 10 or 12-in.
The best way to find out how much base you need is to contact the nearest concrete supplier. If you explain your soil conditions and the slab’s intended use, the supplier should be able to recommend the proper base depth and the type to use and provide contact info for a nearby base supplier. Your municipality may also have a handout of recommended base depths in your area.
