At Block and Rib, we believe that quality construction starts with a solid process. With almost two decades of experience and a proud family foundation, we’ve refined a reliable, hands-on approach to delivering durable, expertly-engineered rib and block slab systems for homes, commercial buildings, and industrial developments.
Here’s how we bring your slab to life, from plan to pour.
1. Quotation & Assessment
Every project starts with a plan and we’re ready when you are.
Send us your architectural or engineer’s drawings via email. Our experienced team will review your requirements and deliver a detailed quote within 3 working days. Whether you’re building a new home or developing a multi-storey complex, we tailor our advice to suit your structure and budget.
2. Engineer-Designed Solutions
We collaborate with a trusted network of qualified structural engineers to design your slab according to South African building regulations and your specific needs.
Your slab will be fully detailed, from reinforcing requirements to load-bearing specs, and backed by a certified engineer's inspection and certificate upon completion.
3. Slab Installation
From preparation to pour, our installation team handles the full slab process:
Propping & shuttering to secure the layout
Reinforcing according to the engineer’s design
Concrete pouring to complete a strong, seamless finish
Every phase is supervised by our on-site team to ensure structural integrity and top-tier workmanship.
4. Manufacturing & Supply
Thanks to our in-house manufacturing capacity, we maintain control over quality and timelines. We produce concrete blocks using two semi-automatic machines and supply:
Rib and block systems
Lattice ribs (reinforced or prestressed)
Custom lintels and concrete elements
We deliver directly to your site, keeping your project on schedule.
5. Beyond the Slab
Our services extend beyond slab work, we bring shape and structure to your building with custom:
Beams and cantilevers
Columns (square or round)
Concrete staircases
Need a unique structural feature? We can shutter and pour almost any form to meet your architect’s vision.
6. On-Site Support & Supervision
We’re more than just a supplier — we’re your building partner. Our team provides continuous on-site oversight and expert guidance throughout the process. Have a question or need advice? We’re just a call or conversation away.
Since 2007, Block and Rib has completed hundreds of thousands of square metres of slab work across South Africa. Our hands-on approach, engineering support, and full-service manufacturing mean you get a slab solution that’s not just functional but truly built to last.
