Planning and Pouring Large Concrete Slabs

pouring large concrete slabs
When pouring large concrete slabs, the first step is to mark the edges and doors with stakes. Then, construct two forms with side boards three inches longer than the width of the slab. Set the end form boards at a 90-degree angle to the other. Finally, attach bracing at every 2′ intervals. When the forms are completed, the concrete is moundED about two to three inches above them. After the concrete has hardened, hoe it to ensure an even distribution. Once the slab is leveled, use a two-by-four screed board to level it.


Once the slab is leveled, it’s time to begin planning the job. Drive stakes at each corner of the site and string a line level between them. Once you have this information, you can level the ground. Next, set the long side form board 3″ longer than the new slab, nailing it to the corner stakes. Continue the process by placing more stakes to mark the edges. If necessary, mark the utility lines under the slab and dig them out.


Next, mark the perimeter of the slab. You can do this by driving stakes in the four corners. After marking the perimeter, string a line level between the stakes. Now, remove any soil in the area to level it properly. Then, place long side form boards that are three inches longer than the new slab. Nail the stakes to these boards, and lay the new slab. Now, you are ready to pour the concrete.


You can now move on to the next step, planning the placement and finishing of the slab. The first step in the process is laying the form board. A long side form board should be at least three feet longer than the new slab. Then, nail the form board to the corner stakes. Once you’ve laid the long side form board, you can start the actual pour. Once it’s level, pour the concrete.


Once the forms are set, place the slab. Then, attach the kickers. Afterwards, you can finish the slab with concrete and apply a protective layer of mortar. If the slab is thicker, it may be higher in some areas than others. Then, it will be less susceptible to cracks and other types of damage. When pouring large concrete slabs, you should also consider the cost of labor. The average cost for laying and finishing a slab of this size is $0.65 per square foot, and it would cost approximately $1800.


The second step in pouring a large concrete slab is to prepare the area for the slab. The ground needs to be leveled. You will need stakes to mark the corners. Afterwards, you should dig the trench and place the forms. Then, you should fill the slab with the form. You should have a poured surface in the ground. After the fill and the slab, you should apply a waterproof coating on the top.
