Crack & shrinkage resistance
Fibres hold the matrix together and control shrinkage cracking.
Added tensile strength
Fibre-Reinforced Concrete
Concrete with structural or micro fibres mixed straight in — no mesh to lay.
Trusted by contractors, councils & developers
Fibre-reinforced concrete has steel or polypropylene fibres mixed through it, adding tensile strength and crack resistance without laying steel mesh. We add the fibre dose on-site so it is distributed evenly through every cubic metre.
No mesh to lay
Reinforcement is in the mix — saving the labour of fixing steel.
Even distribution
On-site mixing spreads fibres uniformly through the pour.
Ideal for slabs & floors
Industrial floors, hardstandings and ground-bearing slabs.

Where fibre-reinforced concrete earns its place
Ground-bearing slabs and industrial floors
Where steel mesh would otherwise be fixed across the whole pour. The reinforcement is in the mix, so the labour of laying and tying mesh goes away.
Driveways and hardstandings
Micro-fibres control the shrinkage cracking that shows up in the first days after a domestic pour, which is where most driveway complaints originate.
Pours where mesh is awkward to fix
Irregular shapes, tight edges and small bays where cutting and fixing mesh costs more in labour than the concrete costs in material.
What fibre-reinforced concrete costs
Fibre adds to the rate per cubic metre and usually removes more cost than it adds.
- The material premium depends on fibre type and dosage — steel structural fibre costs more than polypropylene micro-fibre.
- Against it: no mesh to buy, no mesh to cut, no mesh to fix, and no mesh chairs.
- The labour saving on a large slab is normally the larger number.
- Dosed and billed on the volume actually mixed.

Questions
Fibre-Reinforced Concrete — your questions answered
The things customers ask us most about fibre-reinforced concrete.
Is fibre-reinforced concrete as strong as steel mesh?
It depends on the fibre and the job. Steel fibres are a structural reinforcement and can replace mesh in many ground-bearing slabs, given a design that accounts for them. Polypropylene micro-fibres are not a structural replacement — they control plastic shrinkage cracking as the concrete cures. Where a structural engineer has specified mesh for a designed purpose, fibres do not automatically substitute for it. Our mesh comparison guide covers the distinction in detail.
Steel or polypropylene fibres — which do I need?
Steel where you need load capacity and post-crack performance, typically industrial floors and heavily loaded slabs. Polypropylene where the concern is shrinkage cracking during curing, typically driveways, paths and domestic slabs. They solve different problems, and some specifications use both.
How much fibre goes into a cubic metre of concrete?
It varies substantially by fibre type and by what the fibre is there to do — a structural steel dose and a micro-fibre anti-crack dose are different by an order of magnitude. Work to the rate in your specification. Our dosage guide sets out how the rates are arrived at, and we add the fibre on site so it is distributed evenly through the batch.
Can fibre-reinforced concrete be used for a driveway?
Yes, and it is a common domestic use. Polypropylene fibres reduce the fine shrinkage cracking that tends to appear in the first days after a driveway pour. It does not remove the need for a properly compacted sub-base — typically at least 100mm of hardcore — or for correctly placed joints.
Do the fibres show on the surface?
A small number of micro-fibres can be visible on a freshly floated surface and generally weather away or can be removed at finishing. Steel fibres in a properly finished floor sit below the surface. Finishing technique matters more than the fibre itself.
