At ACI, concrete isn’t just our business – it’s our passion.
Originally founded by the Kerbel family in 1934, the company was acquired by John Harrington and Chris Collett in 2006, marking the beginning of a new era of growth and innovation.
For nearly two decades, their leadership helped shape ACI into one of the Eastern Cape’s most trusted names in precast concrete. Following John’s retirement in 2023, Chris Collett continues to lead the company forward, building on the strong foundation of quality, reliability, and innovation that defines ACI today.
From our base in Markman Industria, just minutes from the Coega Industrial Development Zone, we produce a wide range of precision-engineered precast concrete products for the Agricultural, Building, and Civil Engineering industries.
From lintels, kerbs, and stormwater components to water troughs and rib & block slabs, our products are trusted by the Eastern Cape’s leading builders, farmers, merchants, and developers — helping shape projects that are built to last.
ACI – Built on strength. Trusted for quality. Driven by innovation.
Our Promise
Quality products, delivered on time—every time. At ACI, we’re not just creating concrete products; we’re crafting the building blocks of tomorrow’s communities.
