STAGE 1 Preparation of the site
Removing all topsoil containing grass roots, organic matters and vegetation below the slab area. Then footing excavation of 1200-1300 min based on the soil report started to get rid of all the loose materials. Now sub surface drainage started to be installed. Indeed the service pipe wrapped with 20 mm foam lagging and denso tape tied to underside of the fabric with 2, Y12steel bar) (Wilkie, 2011). Form work is started to be levelled at the same height of the concrete slab.
STAGE 2
Preparing the concrete slab
Under all the pad footing a layer of 15 Mpa blinding concrete, at 50 mm thick is tamped down firmly all over to provide a stable surface for the slab. 0.2 mm vapour barrier is provided as moisture barrier, Then slab fabric is placed Now steel reinforcing trench mesh in beams are placed; so They are cut to fit inside the formwork, with 40 mm cover top and bottom and with 500 mm clearance between the boxing and the bars to make sure all the mesh is covered with concrete completely(Clarke, 2013). CONCRETE is poured from on edge of the form work Then the control joints are placed to prevent cracking of the slab. Curing the slab while protecting it from moisture loss. Then leave it to dry for 28 days.
