Pouring a Concrete Slab

A slab is supposed to be the foundation of an architectural design. Slabs form the support for sheds, patios, carport sheds, farming houses and even for kitchen countertops. Constructing a concrete slab is not as difficult as it seems to be. You can do it right at your home, if you know the correct plan and technique. The cost of the materials are reasonable and you can raise it at home without much effort. In order to get a smooth and level surface, there are some specific methods for pouring a concrete slab.

How to Pour a Concrete Slab

To build a concrete floor, you must plan the design, arrange the materials and then go ahead with the steps. Your plan should include the following points.

• First, determine the type of concrete to be used.
• Estimating the materials needed.
• Concentration of ingredients for raising the concrete flooring.
• Constructing the forms.
• Actual pouring technique.
• Reinforcing the concrete for solidification.
• Finishing the concrete in different ways.
• Allowing the concrete to cure.

Materials Required for Pouring Concrete

• Cement
• Sand
• Grovel
• Shovel
• Hammer
• Wood spikes
• Wire mesh
• Concrete mixer
• Trowel
• Level
• Mason's string
• Pilers

Concrete Pouring Technique

The three things that must be taken into consideration are design, layout and size of the slab. Accordingly, you need to decide the quantity of the mixture. Get the step-by-step pouring technique below.

• Concrete slabs are generally monolithic, i.e made up of single pour. At first, clear out all grass, weed and debris from the ground and then set the slab footings on all sides.
• For adequate space, dig the footing at least 18 inches width and depth. This will form the perimeter of the slab. Chop the wood and then build the frame accordingly. If your concrete wall has broken and you are wondering how to build a concrete block wall, then you must know the basics for building a concrete slab at first.
• After this, you need to place the form boards around the perimeter. You must hammer with double headed nails, so that they can be easily removed later.
• Before pouring the cement mixture, lay a bed of sand inside the wooden frame. The sand bed should be 2 inches deep and make sure you rake it smooth with water. Place the rebar rods over stools and mesh the sand bed with wires to cover open slab area.
• Prepare the mixture with the help of mortar and pastel or a concrete mixture. The composition should be made in such a way, that the liquid forms a strong base after solidification.
• Since, it's a monolithic slab, pouring is done at one shot to get a uniform layout. Now pour the mixture from the container starting from the end till the other corner of the frame. Ensure that the entire slab area is covered.
• Use a screed board to smooth the surface. There should not be any air bubbles over the liquid concrete. You can even use a bull float to level the surface and make it intact. Allow it to dry for a few days. Once the cement solidifies completely, wet with water regularly. This makes the slab strong.

Points to Remember

• As soon as you make the mixture, pour it immediately. This prevents drying of the concrete mix.
• The ground bed should be completely dry, smooth and flat.
• The weather should be bright and sunny. Cement needs some time to dry and rain is detrimental for a good quality slab. A concrete waterproofing also helps to overcome this problem during rain.

Pouring a concrete slab can be done easily at home. You will gather some experience once you have tried it. The consistency of the mixture and the flooring is vital for good results.
