Digging out the hole correctly is a vital stage in creating a shed base. dig a hole to a depth of at least 6-inches. then, attach a piece of string to two pencils to find out if your excavated base if level. insert a pencil at each side of the hole, 6-inches down, and remove any surplus soil that sits above the string, until the base is level.. 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.. At the most rudimentary level, think of a slab foundation as a single piece of thickly poured concrete uniformly shaped with a flat, level surface. below ground, the pour will typically be thicker and deeper around the edges, giving the slab a strong footing on which to rest..
Ok crazy idea, but im thinking of building a new shed and the bottom couple of foot would be below ground with a concrete base and brick wall around up to ground level so i could gain mor internal. I am laying down a concrete base for my 16' x 10' timber shed / workshop. i have dug down 5 inches below ground level and am planning to lay: 4 inches of compacted hardcore a layer of sand damp proof membrane then 4 inches of concrete (so the concrete should finish about 3 inches above ground level.). Ground level is the surface of the ground immediately adjacent to the building in question. where ground level is not uniform (e.g. if the ground is sloping), then the ground level is the highest part of the surface of the ground next to the building..
