A parking deck is not a floor you walk on. It carries cars, so the slab above the membrane is built to a different standard than a screed indoors.
1. The edge strip goes down first, around the whole perimeter — 80 m of it here. The slab has to be free to move against the walls; a slab cast tight into a parapet cracks at the corners in the first summer.
2. Two layers of mesh, not one. Wheel loads are point loads that move; a single layer at mid-depth does not hold the top surface together under them.
3. Every service, sleeve and duct is set before the pour. Once 200 mm of concrete is down, adding one pipe means cutting the deck open — and cutting the deck open means opening the waterproofing under it.
4. C25/30 with polypropylene fibre, 270 m², about 61 m³, placed and levelled by hand over the mesh. The fibre works against early shrinkage cracking, which is what you get on an open deck under a Cyprus sun.
Everything above the membrane is replaceable. This layer decides how the deck behaves for the next thirty years.
