Concrete Flooring for Underfloor Heating

Discover how your concrete flooring can benefit from underfloor heating in our handy guide.

For many years, concrete flooring was predominantly used at industrial sites due to its hardwearing and easy to clean attributes.

However, thanks to these characteristics, polished concrete has now risen to become a favoured flooring solution for the domestic market. Serving in new-build developments and home renovations alike, it can supply a sense of luxury and contemporary visual appeal.

Concrete and underfloor heating

Concrete floors have a high thermal mass. This makes them an outstanding finish where underfloor heating systems are installed. Concrete can deliver rapid ramp-up times but also retains heat effectively. It can even store warmth supplied by solar gain.

Concrete Floor Types

There are three main concrete floor finishes used with underfloor heating: polished concrete screed, polished concrete overlay and concrete pour.

Polished Concrete Screed

Polished concrete screed involves the application of a shallow layer of liquid screed that is self-levelling to the existing subfloor, which is polished after drying.

Polished Concrete Overlay

Polished concrete overlay refers to a thinner layer of concrete that is deployed over existing concrete flooring, which has suffered damage and works like a veneer.

Concrete Pour

Concrete pour is perhaps the most common concrete flooring type, and features a deep concrete layer poured directly into position, which is then cured and polished.

Underfloor heating systems that work with concrete floors

Concrete’s proven heat-retention qualities make it an excellent floor finish above underfloor heating. It can work with both hydronic (water-based) and electric underfloor heating systems.

Water-based Underfloor Heating and Concrete

Polished concrete overlay refers to a thinner layer of concrete that is deployed over existing concrete flooring, which has suffered damage and works like a veneer.

Electric underfloor heating and concrete

Concrete pour is perhaps the most common concrete flooring type, and features a deep concrete layer poured directly into position, which is then cured and polished.
