How to build up internal door step height on top of DPC Help, advice, information, answers and tips on all types of flooring from laminate and carpet to timber and vinyl

[TeaCup2026]

I need to build up the internal door step height by around 12mm to meet the existing concrete base so that a moisture tolerant self-levelling compound can be poured.

The material used to build up the height will sit directly on top of an existing DPC. What is the best material to use?

Hi teacup2026,
Probably best to use selflevelling compound - use one with latex, 12mm is too thin for a concrete screed.
