In every construction project that involves the use of concrete, getting the right proportions that go into the concrete mix is a critical requirement. The process of building a slab is the same regardless of its size.
Here, you will find using a concrete slab calculator to be a useful tool in helping you get the materials and ratios right, all the time.
However, here is what should come first:
The subgrade goes in before the concrete, and if there are drainage problems, there will be high chances are that your slabs will crack. You will, therefore, require first, digging out the area where you will place your concrete slab and pouring a thin layer of gravel. You will then pour dirt over the gravel layer, and flatten the layer of soil to create a level concrete slab.
The size of the area on which you will be placing your slab will determine the amount of concrete mix you need. Getting the concrete ratios wrong will cost you a structure with compromised strength, thereby leading to wastage of resources. Too much concrete will overflow your area and will call for thorough cleaning, and less concrete will also compromise on the quality of your slab.
You can opt to source for your concrete products from a local supplier, but you need to send them the right measurements before they deliver the concrete.
Placing the Concrete
After the concrete mix is ready, you need to have a well-prepared surface for the pouring. You will need to lay a concrete floor reinforcing mesh for stronger support. Also, stamp the surface for the gravel to settle and the concrete to rise. It is advisable that you smooth the slab surface before the concrete cures completely.
Creating a slab in the right way ensures its longevity of use without chances of cracking. Reinforce your concrete using a concrete floor reinforcing mesh in your next project for a firm and durable concrete slab. Also, consider using a concrete slab calculator to determine the correct measurement of on-site materials that you will need.
