Concrete Screed Minimum Thickness?

The Concrete Screed Minimum Thickness?

I’m Andy Parkin, Managing Director of the Multi-Award Winning Speed Screed.  We are often asked about, what is the concrete screed minimum thickness?

Often people are having issues with thresholds and the heights of ceilings (not having a lot of floor make-up), and they want to know what is the minimum.  Laying the screed too thin, may result in failure, leading to the possible replacement of the screed.

Concrete Screed Minimum Thickness – Construction Types

A traditional screed as defined by the British Standard for screed, can go down to 40mm bonded.


  • That would be 40mm onto a concrete substrate.


  • If laying on top of a membrane, that would be classified as unbonded, and the minimum would be 50mm.


  • Laying onto the insulation, so that would be classed as floating construction, domestically the British Standard recommends 65mm minimum and 75mm commercially.

Specialist Concrete Screed Minimum Thickness

  • Specialist screeds will allow you to actually bond as low as 10mm, and 35mm for floating construction.

You can see there is are a few different options, but you have got to be very wary of the minimums and realise the minimum is always going to be from the high spot within the room.

For further information about minimum’s please feel free to contact us.
