The Foundation The floating raft table top foundation or a conventional type of foundation is designed and certified by a Structural engineer. The foundation will consist of starter bars at specified intervals to anchor the wall system of the super structure. Foundation will have starter bars. Erection of Formwork The Superstructure The reinforcing of the walls of the superstructure is certified by a structural Engineer. The compressive strength of the walls are between 10 and 15 mPa. The walls are SABS certified. All the walls have a minimum height of 2,400 mm and can be increased to 2,700 mm or 3,000 mm. Internal walls can either be 100 or 150 mm thick. External walls can either be 100 mm or 150 thick. The Roof The gabbling can be at any degree depending on the design of the roof. The roof design is certified by an engineer. The roof ties are coupled to the reinforcing within the wall, which are positioned prior to casting. No beam filling is required, as we use steel block-outs to create the cavities to position the perlings. The Window and Door Frames Wooden or aluminium window frames are inserted into a pre-planned cast opening after the formwork has been removed. Steel doorframes, or wooden doorframes, are cast into position and are secured after the walls have been cast. Electrical Applications The electrical plug boxes and light switch boxes are fixed into position on the formwork. This eliminates the need to chase the walls. The Plumbing The plumbing pipes are located into position prior to casting. This eliminates the need to chase the walls. Reinforcing The reinforcing is designed according to the requirements of the structure and specified by a professional Engineer. All walls will be reinforced up to roof level as per the design of a structural engineer. The reinforcing is determined based on the prevailing soil conditions on location, such as clay, sandy soils, collapsing soils, dolomite etc. Mortar Mix Design The density of the mortar will depend on the grading of the sand. 1,600 to 1,800 Kg per cubic meter. A compressive strength of between 10 and 20 mPa can be achieved in a 28-day period. As the structure is uniformly constructed, with reinforcing in place, the building is more resistant to seismic movement (Monolithic design). The mortar mixture produces a fast curing aerated mortar with easy flow, is waterproof and has good thermal and sound insulating properties. The mortar cures and sets by following morning, before the formwork is removed. There is no need to vibrate the mortar to achieve a smooth finish. The electrical and water piping is installed in the cavity of the formwork cast in situ. Page Top
