Step Two: Mark and Measure the Area for the Slab
Figure out precisely where your concrete flooring will be located. Mark out the exact area with string line and stakes. Use a measuring tape to get the exact measurements of the slab concrete that you will need. These measurements will be used to calculate the amount of concrete that you will need to order.
The steps for making this calculation are as follows:
Step Three: Create the Formwork for Your Concrete Pad
The next step in laying a concrete slab for your garden shed is creating the formwork that will support the wet concrete while it dries, sets and cures. The measurements that you made in the preceding step will come in handy here. First, make sure to have the right tools and supplies on hand. In terms of tools, you will need a hammer, timber pegs, a level, a measuring tape, digging tools and a carpenter’s square. In terms of materials, you will need timber that is the same height as the desired thickness of your concrete floor slabs. Based on our example above, two of the lengths of timber will need to measure four metres; the two other pieces will need to measure 4.2 or 4.8 metres in length. The end result needs to produce an internal measurement that adds up to the desired dimensions of the garden shed slab.
Once you have assembled the appropriate tools and supplies, place the pieces of timber in the right formation. Before you nail them together, use your carpenter’s square to ensure straight, true right angles. Position the completed framework precisely where you want to build a concrete slab. Mark the area so that you can see exactly where you will need to dig.
