What Is the Rib and Block Slab System?
The rib and block system is a popular and proven method for creating suspended slabs. This system consists of pre-stressed concrete ribs spaced at regular intervals, with infill blocks placed between them to create a flat working surface. Concrete is poured over the entire assembly to create a strong, reinforced slab.

Polystyrene (EPS) Slab Blocks

Advantages of EPS slab blocks:
- Significantly lighter weight, reducing structural load
- Faster installation due to easier handling
- Lower transport costs
- Superior thermal insulation, contributing to energy efficiency
- Compliant with new energy-efficiency building regulations

- Suspended ground floors and renovations
This versatile system reduces shuttering requirements, simplifies reinforcement, and allows quick, clean, and efficient installations, especially in confined or difficult-to-access areas.
