Simple madness – For pouring all kinds of foundations for permanent garden equipment, e.g.. brick benches, crickets itp. you can make a simple strip formwork of an old PVC floor covering. The pile in the right position is held by a suitably bent wire driven into the ground. When pouring foundation slabs with a thickness of 15-25 cm it is enough to use a wire with a diameter 6 mm. It should be pushed firmly into the ground, so that the poured concrete does not deform the formwork, although in the case of garden structures it does not matter.
