Building a shed base how to build a concrete shed base including damp proof membrane. the slab itself is designed to be above ground and is 6 inches thick. for small sheds this could be dug into the ground removing the need for any brickwork around the edges. this is more of a cosmetic finish to the base, just to tidy it up.. For most buildings a concrete thickness of 3" (75mm) is fine, on some of the larger buildings & depending on use increase this to 4" (100mm) laid on compacted hardcore or type 1 roadstone may be required.. Would like the start a diy shed that is 8x8. how thick of a pour do i need to support this? is concrete even needed or should i go with a pea gravel and treated lumber base. not sure how much concrete would be needed or how much compare to moveable base..
A shed base is an essential part of building a shed (whether they may be wooden or metal garden sheds), the base has to be properly made to give your shed a solid foundation.. Concrete slabs intended for exceptional loads, such as commercial yards, lorry parks etc., will be at least 200mm thick and should be specifically designed as they will probably require a sub-base of at least 100mm thickness, and steel reinforcing mesh or a fibre-reinforced concrete.. Our concrete calculator allows you to accurately work out the amount of concrete you'll need for your project. simply add the measurements for your concrete order to the relevant shapes above (you only have to fill in the shape/s you want to use) you can build up a concrete calculation for complicated areas by adding additional shapes of each type..
