The Complete Guide to Building a Concrete Slab

TLDRThis video provides a step-by-step guide to building your own concrete slab, including calculating the amount of concrete needed, choosing between bags or a concrete truck, preparing the area, and pouring and finishing the concrete. It also includes tips on reinforcing the slab and creating expansion joints.

Key insights

⚒️Calculating the amount of concrete needed is essential before beginning the project.

🚚Decide whether to buy bags of concrete or have a concrete truck deliver the concrete.

🎯String lines along the perimeter of the slab to ensure it slopes away from the house for proper drainage.

🔄Use two-by-fours as forms for the slab and stakes to hold them in place.

🔧Reinforce the slab with wire mesh or rebar to add strength and stability.

Q&A

How do I calculate the amount of concrete needed?

Use a concrete calculator online, inputting the thickness and dimensions of the slab.
