We recommend a Rebated Concrete Floor for your Car Garage
What Is a Rebated Concrete Floor for a Steel Garage Shed?
- A rebated concrete floor is a concrete base with a shallow step (lowered channel) formed around the edges—usually at the doorway—so the steel garage sits slightly down into the concrete instead of on top of it.
- Think of it as a built-in lip that the shed fits into.
What Does “Rebated” Mean?
- “Rebated” simply means:
- Part of the concrete is set lower than the rest
- So instead of one flat slab, you have:
- Main floor level (where your car sits)
- A lower edge/channel (where the shed walls sit)
How It Works in Practice
- With a rebated base:
- The steel walls sit inside the concrete
- The doorway sits behind a small concrete lip
- Rainwater is deflected away
- Wind can’t blow under the shed
- This creates a tighter seal between the shed and the base.
Why It’s Ideal for Steel Car Garages
- A rebated base is especially good for garages because it:
