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 waterproofing requests in the area come from:
- Family homes: sealing a leaking flat roof over a garage or patio, or a damp floor slab in an older house
- Complexes and apartment blocks: membranes on roof slabs, podium decks and balconies, plus repairs to leaking basement parking
- New houses: coating a new flat roof slab and treating basement or retaining walls before backfilling
- Shops, offices and restaurants: treating flat roofs above shops and offices, and damp basements, lift pits and service floors
- Warehouses and factories: sealing roof decks, bund walls and sumps in factories, and protecting slabs in wash bays
- Extensions and backyard rooms: waterproofing the roof of a new room and the joint where it meets the existing house
