Concrete work in Gauteng
Gauteng is the busiest concrete market in the country. Housing estates, townhouse complexes, offices, warehouses and mines all keep contractors and ready-mix plants working. Ground conditions vary a great deal. Expansive clays heave in parts of the province, dolomite underlies much of the West Rand and Centurion, and engineers set foundation and drainage rules for those areas under SANS 10400-H. Highveld winters bring frost on fresh pours, and summer storms arrive in the afternoon. Ready-mix plants are close to most suburbs, so trucks and pumps reach sites quickly, though estates may limit delivery hours and gate access.

Typical concrete waterproofing requests in the area come from:
- New houses: coating a new flat roof slab and treating basement or retaining walls before backfilling
- Complexes and apartment blocks: membranes on roof slabs, podium decks and balconies, plus repairs to leaking basement parking
- Family homes: sealing a leaking flat roof over a garage or patio, or a damp floor slab in an older house
- 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
