Concrete work in Johannesburg
Johannesburg is built on ridges of quartzite and shale with pockets of expansive clay, and old mining ground means engineers often review foundations. Dolomite is mainly to the west and north. Work ranges from backyard slabs and driveways in the northern suburbs to apartment blocks, office floors and warehouses in the south. Winter nights bring frost, and summer storms can stop a pour. Ready-mix plants are spread around the metro, so most suburbs are within a short drive. Congested roads, steep plots and tight estate gates affect truck timing and pump positioning, so ask about delivery windows and minimum loads.

Typical suspended slabs requests in the area come from:
- Family homes: a first floor or balcony slab added to a family home, poured on props over existing walls
- Complexes and apartment blocks: repeated floor slabs for townhouses and apartment blocks, cast level by level over steel props
- New houses: the first floor slab of a new double storey house, cast once the ground floor walls are up
- Shops, offices and restaurants: an upper floor or mezzanine slab in a shop, office or showroom, designed for heavier loads
- Warehouses and factories: a heavy suspended slab for a mezzanine, loading deck or plant platform, designed by an engineer
- Extensions and backyard rooms: a new room or second storey slab over an existing house, often needing pump access through a tight yard
