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.

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.
