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 concrete roof slabs requests in the area come from:
- Family homes: flat roof slabs over garages, patios and extensions on existing family homes
- Complexes and apartment blocks: roof slabs and podium decks for townhouses and apartment blocks, with waterproofing and drainage
- New houses: roof slabs for new homes, poured to a fall and waterproofed before handover
- Shops, offices and restaurants: flat roof slabs for shops and offices that carry plant, tanks or solar panels
- Warehouses and factories: heavy roof slabs and plant-room decks designed for equipment loads
- Extensions and backyard rooms: roof slabs over backyard rooms and granny flats, often built to carry an extra floor later
