Pouring Concrete Slab For Garden Shed

In this video we go over how to pour a easy beginner concrete shed slab.

Pouring concrete slab for garden shed.

A 4 inch slab is generally a good thickness for a typical shed. Kickers slant down into the ground and keep the top of the stakes from bending outward. A rake and spirit level would be the best tool to help yourself in the leveling process. Concrete makes a permanent slab on which to build or place your shed but it is brittle.

You can use steel rebar or steel mesh or opt for having synthetic fiber added to the concrete before pouring. There are a couple of different ways to pour the concrete slab. That requires an excavation of at least 6 inches to make a slab that will be 2 inches above the surrounding ground. 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.

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. The best way to avoid this is with extra strong bracing. Freshly poured concrete can push form boards outward leaving your slab with a curved edge that s almost impossible to fix. Spread the mixture to all corners and just level it up well.

The right concrete slab thickness is critical. And an overly thick slab will cost more than it needs to and be more difficult to put in. Place 2x4 stakes and 2x4 kickers every two feet along the form boards for support. Calculate the area in cubic metres.

A lumber frame sits on top of these piers. To do this multiply the area in metres squared by the desired thickness of the floor in metres. You can also hire a cement mixer from places such as kennard s or coates hire. Determine the area of the slab floor which is measured as length times width.

It s an ideal foundation for securing your shed garage or carport. A thin brittle slab will crack under the weight of the shed and what you put in it. If your shed concrete slab needs to measure 4 metres by 4 metres its area is 16 metres squared. The minimum concrete slab thickness we recommend is 100mm.

This concrete floor can be poured in most locales on a 4 inch base of compacted gravel.
