1. Set up the scaffolding / props
After correct measurements of the building have been received through a plan or physically taken from site and the amount and size of concrete waffles to be used given by our qualified personnel, props and soffites are erected in site as prescribed in readiness for the placement of the concrete waffles. The propping is done separately for every room.
2. Laying of concrete waffles
Concrete waffles are lifted either manually or by use of cranes and arranged in accordance with the propping and layout plan produced after the plan is received.
3. Place framework at edge of slab
Soffites of slabs and sides of beams where required
4. Placement of reinforcement bars
Reinforcement steel bars are laid such that there is a bar running alongside every rib of the concrete waffle. The type of reinforcement bar used depends with the span of the room, with big room spans using Y16 steel bars while small span rooms use Y12 steel bars. At this stage various mechanical and electrical works too are done as well as lying of the BRC mesh.
5. Lay electrical conduits
Mark positions of junction boxes on the underside of waffle blocks to allow hole to be cut when in-situ concrete has gained strength.
6. Place fabric mesh reinforcement on topPlace a 50mm thick layer of concrete on top of mesh reinforcement allowing to settle between waffles and in beams.
7. Pouring of concrete
Concrete is then poured to a thickness of 2 inches over the apex of concrete waffle after which the slab is left to cure.
8. Vibrate adequately the freshly placed concrete
9. Cure the concrete for at least 7 days
10. Remove scaffolding and formwork after 21 days
Testing of Waffles
Our waffles have been tested and proved for being strong and firm enabling the to handle heavy weight.
