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. Bonded
That would be 40mm onto a concrete substrate.
Unbonded
If laying on top of a membrane, that would be classified as unbonded, and the minimum would be 50mm.
Floating
Laying onto the insulation, so that would be classed as floating construction, domestically the British Standard recommends 65mm minimum and 75mm commercially.
