You can either a do it yourself using materials purchased from your local hardware store like peter young and his son did with their shed click to see how they did it. We go take you from start to finish on this job of how we accomplished a 8 x 10 shed. You can also hire a cement mixer from places such as kennard s or coates hire. In this video we go over how to pour a easy beginner concrete shed slab.

A thin brittle slab will crack under the weight of the shed and what you put in it. Spread the mixture to all corners and just level it up well. The minimum concrete slab thickness we recommend is 100mm. A rake and spirit level would be the best tool to help yourself in the leveling process.

A lumber frame sits on top of these piers. That requires an excavation of at least 6 inches to make a slab that will be 2 inches above the surrounding ground. If your shed concrete slab needs to measure 4 metres by 4 metres its area is 16 metres squared. A 4 inch slab is generally a good thickness for a typical shed.

Freshly poured concrete can push form boards outward leaving your slab with a curved edge that s almost impossible to fix. The best way to avoid this is with extra strong bracing. To do this multiply the area in metres squared by the desired thickness of the floor in metres. This design is normally made up of seven or more concrete piers that are made by digging 4 feet down and pouring concrete into a mold placed in the hole.

You can use steel rebar or steel mesh or opt for having synthetic fiber added to the concrete before pouring. And an overly thick slab will cost more than it needs to and be more difficult to put in. Dig up the ground from the marked points and lines about 2 3 inches deep and just pour the concrete mixture for the shed slab. It s an ideal foundation for securing your shed garage or carport.

There are a couple of different ways to pour the concrete slab. Kickers slant down into the ground and keep the top of the stakes from bending outward. Place 2x4 stakes and 2x4 kickers every two feet along the form boards for support. Determine the area of the slab floor which is measured as length times width.

The right concrete slab thickness is critical.
