Sometimes reinforcing steel is put in concrete to strengthen it, help hold the concrete together and limit cracking. In many cases, bigger concrete jobs that require reinforcing steel usually also require a building permit of some kind, in which case the reinforcing steel requirements will be documented on the plans. It's worth noting however, that although some bigger jobs (such as driveways which take heavy traffic, carport floors and larger shed floors) might not require a permit, it could well be a good idea to include steel reinforcing. The average reinforced floor usually comprises a continuous footing (trench filled with concrete) around the perimeter, with the rest of the concrete slab being 100mm (4") thick.
Welded wire mesh is steel wire welded together to form a flat sheet with a square grid pattern. Even though it is made of 'mild' steel, the reinforcing steel does not rust inside the concrete. A step-by-step example of how to make a concrete slab floor for a 1800mm x 1800mm (6ft x 6ft) garden shed. Cut two pieces of formwork lumber exactly 1800mm (6ft) long and cut another two pieces approximately 2400mm (8ft) long. When the formwork frame is square, nail a piece of lumber on top of the formwork frame from corner to corner, to make sure the formwork frame remains square until pegged in place.


The formwork is now ready to be picked up and carried into position, but first make sure that the ground has been prepared, that is, made level, with all vegetation and any soft ground removed.
Nail the pegs to the formwork but not all the way in, as the nail will need to be pulled out later.
Dig a trench around the perimeter of the floor area about 100mm (4") deep and about the width of the spade wide or about 200mm (8"). Concrete that carries heavy loads (such as footings, foundation walls and columns) almost always requires reinforcing steel. Concrete projects such as pathways, some driveways and small shed or playhouse floors, generally do not require any steel reinforcing at all. And sometimes smaller jobs also benefit from reinforcing steel, especially if the sub-ground is less firm than it should be or there are pockets of spongy sub-ground. This is because steel needs oxygen to rust and once the concrete has cured, the steel is starved of oxygen. The simplest way to make the pavers concrete is just by purchase it at the market with its expensive cost. The lumber should be straight but a low quality grade will do since it will eventually be discarded. Nail the four pieces together so that they make up a square with inside measurements of 1800mm x 1800mm (6ft x 6ft).


Ensure that it is level and then secure it by hammering pointed 50x50 (2x2) or 50x25 (1x2) pegs at 900mm (3ft) intervals against the outside of the formwork.
This is like a 'footing' to give the perimeter of the concrete floor more depth and strength, as that is the part of the floor that will be supporting the shed walls.
In fact even for a smaller shed floor, it does not hurt to throw in a steel rod (rebar) around the perimeter of the floor to give great added strength. The mesh should be positioned in the top half of the thickness (slightly above the middle) of the concrete slab.
That is why it is especially important to ensure there is ample concrete surrounding the reinforcing steel. Solid concrete steps, made on site, are heavy and therefore, they are likely to settle over time. I think it is not wise when you buy it but actually you can make it by yourself just by applying some simple steps. Unlike solid concrete steps, precast concrete steps are hollow, lighter and less prone to settle.
