Sure you can, vertical and horizontal construction joints are allowed in the Raft with depth of 3.00 meters and above in hot countries , to avoid differential temprature between the core of cast and concrete temperature at the time of cast, the recommended depth should not exceed 1.5 with temperature control sensors and proper immediate curing
If the soil is so lose that it cant hold the building even with pile foundation. So, piled raft foundation is used which make the building to float like a boat. That obeys Archimedes' principle-it is buoyed up by the weight of the earth displaced in creating the foundation.
The raft will help to avoid any settlement that would occur to strip the foundation. The mat is just placed there to avoid slipping.
1. Excavation of the soil up to required depth.2. Ramming the foundation bed.3. Cutting the concrete over the reinforcement.4. Laying the reinforcement over the the foundation bed.5. Pouring the cement concrete over the reinforcement.

The construction joint should be placed where there is the least amount of impact. This could include the slabs. These types of foundations are used in the United Kingdom and Australia.
The best location to set the construction joint is less shear force impact. e.g:In slabs;it is better to locate between the supports.
Raft foundation is reinforced concrete slab that is supported on a compacted hardcore base that is bigger than the raft. The procedures in construction the foundation involves checking the soil properties, and making the edge of the raft stepped to make a toe so the outer leaf of the wall goes below ground. The slab is reinforced with steel, a radon barrier is added, and a damp proof course is put in.

The perimeter beam around the edge of a raft foundation.
The main advantage of a raft foundation is that it is more economical. Another advantage is that it requires little excavation. The disadvantages of raft foundations are that there is a greater potential for erosion, and they require specific treatments to bear a load.

It are a Afrikaans way of saying Raft Foundation.
If the soil is so lose that it cant hold the building even with pile foundation. So, piled raft foundation is used which make the building to float like a boat. That obeys Archimedes' principle-it is buoyed up by the weight of the earth displaced in creating the foundation.
Types of raft foundation are 1. Solid slab raft 2. Beam and slab raft 3. Cellular rafts
They r the same. There is no difference.
The raft will help to avoid any settlement that would occur to strip the foundation. The mat is just placed there to avoid slipping.
