How we score

Every number on this page comes from public Google data as of the date shown, not opinion or payment. Rating is the company’s live Google star average. Review volume shows how many customers have rated them, ranked against other Johannesburg concrete companies. Confidence weighs the rating by that volume. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

How much does concrete work cost in Johannesburg? (2026)

Pricing depends heavily on whether you need decorative finishes, a custom precast piece, or bulk ready-mix supply for a construction site. This is general guidance on what drives price, not a quote from any specific company on this page.

Serving all of Johannesburg

These companies cover Industria, Heriotdale, Kew, Booysens Reserve, and Sandton, giving builders and homeowners options across greater Johannesburg. Searching for a concrete company near me? Every listing below shows a live phone number and directions so you can reach the closest option fast.

What to ask before you hire a concrete company

  • Is this a decorative finish, a precast product, or bulk ready-mix supply?
  • Can you deliver a custom piece from my own drawing or specification?
  • What’s the lead time for the order, and how is delivery volume confirmed?
  • Do you offer installation, or is that a separate contractor?
  • What’s the warranty or durability guarantee on the finished product?

Frequently asked questions

How did you choose these companies?

We started from every concrete company in Johannesburg with a public Google presence, then ranked by rating, review volume, consistency, and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

Where can I buy bulk ready-mix concrete for a construction site?

AfriSam Wynberg is the dedicated ready-mix concrete supplier on this page, geared toward bulk, contractor-scale orders rather than decorative or precast products.

Which company makes precast garden ornaments and furniture?

Old World Concretes and MODCON PRECAST both specialise in precast products, from garden ornaments and columns to custom tables built from client drawings.

The bottom line

Cemcrete is the safe default for decorative concrete finishes on the deepest review base, while Old World Concretes is the specialist for precast garden and architectural pieces with a century-long track record. For bulk ready-mix supply, go to AfriSam and confirm delivered volume on-site.
