Process of Setting Out Your Concrete Job
Whether you are laying a floor slab, concrete driveway or a footpath, the basic procedure is the same. The main difference lies in the thickness of t
he slab. Firstly locate and lay out the areas to be concreted using string lines. Remove the topsoil to about 100mm below the desired finishing level. Compact and level the whole area to be concreted, allowing for a slight slope away from buildings for drainage purposes. Placing your 100mm x 50mm timbers for the formwork side rails, drive wooden stakes firmly into the ground at no more than 1.2m apart. The rails should then be securely nailed to the stakes. Extra stakes need to be placed at every joint in the rails and at corners. Level the formwork carefully using your straight edge and spirit level.
