Machine-trowelled to a hard, dense, smooth surface
As the slab sets, a machine works the surface — a walk-behind power trowel for smaller areas, a ride-on copter for larger ones. The blades compact and close the surface, driving the fines down into a dense skin considerably harder than a hand-finished one.
You end up with a floor that is flat, tight and easy to live with. Outside is a different story — smooth plus wet is slippery, so driveways and pool surrounds want exposed aggregate or a brushed finish instead.
Where it belongs
- Shed slabs — the standard finish for a shed floor
- Garages and carports — easy to sweep, easy to get oil off
- Workshops — flat enough for a bench, a hoist or a roller cabinet
- Warehouse and industrial floors
- The right base for polished concrete or an epoxy coating later
- Not for driveways, pool surrounds, patios or paths
What machine trowelling actually buys you
Flatness
A workbench that rocks and a roller cabinet that runs to one corner both come back to the slab.
Hardness
Compacting the surface makes it denser and more abrasion resistant than a slab that was screeded and left.
Less dust
A closed surface sheds far less of the fine powder a raw slab produces underfoot.
Easy to clean
A tight surface does not absorb oil and spills the way an open one does, so they clean off instead of soaking in.
The ones we get asked most
Can I have this finish on my driveway?
We do not recommend it and we will not pour it outdoors. It is slippery wet. For a driveway you want exposed aggregate, coloured concrete or a brushed finish.
Do you do polished concrete?
Yes. Polished concrete is a separate process — grinding and polishing the cured slab — and it is a popular workshop, garage and interior floor. Tell us at quoting stage so the slab is poured and finished with polishing in mind.
Power trowel or copter?
A walk-behind power trowel suits smaller and tighter areas and works into corners. A ride-on copter is for larger pours where speed matters. Either way the finish you are paying for is the same.
Can it be coloured?
Yes, oxide can go through a slab that is being machine-trowelled. It works well under a polish.
Will it still crack?
Control joints are still cut, and they are still what stops random cracking.
How long until I can use it?
The slab needs to gain strength before the shed goes up or a vehicle goes on it. We give you the dates when we finish the pour.
