A new name in concrete slabs

CSS began trading in 1994. The vision of the founders was clear: to become Gauteng’s leading supplier of concrete slab products and services.


A decade of innovation

We never rest on our laurels, but rather we continue to research and develop our products. We challenge the status quo every day.


Promoting products & services

By expanding our research and development facilities, we’re able to continuously develop innovative new products and add to our knowledge.


Laying the foundations for growth

By training and upskilling our people, we’re empowering them to help grow South Africa’s construction industry.


Building for life

The first CSS slabs to be laid and installed are still going strong, 25 years later, and still contributing to Gauteng’s built environment.

Don’t just take our word for it…
