Amalgamated Concrete are professionals in the supply and construction of suspended slabs.
What is a Rib and Block Suspended Slab System?
The two-part system, consisting of ‘ribs’ and ‘blocks’, form permanent shutters for the quick and economical construction of floors in multi-story buildings.
The ‘ribs’ or lintels are reinforced precast concrete sections that are used to span between walls. The reinforced steel comes in the form of lattice, protruding positively from the concrete to strengthen the lintel for transport and to supply shear strength in the floor. The lattice is tied into steel mesh and other before casting of concrete.
The ‘blocks’ are hollow section precast units, placed to span the ribs, thus completing the shutter. The steel lattice are tied into steel mesh and other supporting structural components and the floor is cast in with concrete.
With this innovative Rib and Block Slab System, Amalgamated Concrete can assist with
- Suspended flooring
- Suspended concrete slabs

Benefits of the Rib and Block Slab System
Suitable for applications in all types of buildings where suspended floors are required
The system is ideal for residential houses
Rib and Block are quicker and less costly to build than traditional shuttered concrete.
Ideal composite action between lattice lintels and cast-in-situ concrete, optimizing strength/material requirement for cost saving
The best solution for complicated in shape slabs with skylight openings and cantilevers
Simple and quick to install even with unskilled labour
Rib and Block Slabs are assembled by hand
no cranes or other machinery required whereas hollow core slabs are very heavy and require cranes to assembly
