Then, make a slab frame using wood on the surface where you plan on making the slab.

Step 2- Dig The Area and Add Gravel:

Dig down the place at least 4”. Now, place the gravel evenly making it 4-inch thick.

How To Pour A Concrete Slab For A House?

Did you know that you don’t need to hire anyone to pour a concrete slab for a house, rather you can do so by yourself? Well, if you didn’t, then keep on reading below and find out more about it!

How to pour a concrete slab for a house? You can easily pour a concrete slab for a house by following six simple steps. These are building the framework, measuring and digging the area, preparing the bedding, preparing the concrete mix, placing the slab, and finally curing it.

Follow the steps down below to pour a concrete slab for a house-

Step 1- Build The Framework:

Concrete related projects will always need a framework at first. Making a concrete slab for a house requires the same.

Using precise measurements of your choice, make a framework out of wood and use nails to attach the whole thing. Make sure the framework is strong and made after proper calculation.

Step 2- Measure and Dig The Area:

Using the framework, mark the area where you want the slab to be. Use a spade for this.

After measuring, remove the framework and dig out the place according to your required depth. Make sure to dig an extra 5 cm of depth for the bedding along with the one required for your concrete slab.

Step 3- Prepare The Bedding:

Now, place the framework back and it’s time to lay the bedding. You can use crusher dust or a bed of road base for this.

Lay the bedding making it 5 to 6 cm thick and level it. This is done to provide the slab with a sturdy base.

Step 4- Prepare The Concrete Mix:

Now, prepare the concrete mix of your choice according to the package instructions. Make sure to maintain safety precautions for this process.

Also, be careful to not add an unnecessary amount of water to your concrete mix. Because, it might damage the concrete’s quality.

Step 5- Place The Slab:

From one edge of the framework, start pouring the concrete mix and keep it spreading with a shovel. It’d be great if two people work simultaneously in this process. Make sure to leave no spot unfilled.

When the concrete becomes a bit dry, flatten it. If you want a rough surface, you can run a broom over it afterwards, to make patterns as per your wish. Run an edging trowel around the slab’s perimeter as per needed. You can also run a jointing trowel over the slab if it’s large enough for that to avoid cracks in future.

Step 6- Cure The Slab:

After you’re done with everything and prepared for obtaining the final result, let the slab cure. Before that, you need to remove the framework.

After a day you’ve poured the mix, you can take out the framework. Then, let the whole thing cure for a week and you’re good to go!
