The Difference Between Concrete and Screed
Concrete and floor screed may sound like very similar materials on paper, but they’re used for very different purposes on site.
Both concrete and floor screeding are made using cement, water and aggregate (such as sand or gravel), but different types of aggregate are added to each. This means that concrete is much rougher, while floor screed is finer in texture.
In concrete flooring, a coarse aggregate such as gravel (small stones) is included to give the mixture more strength, making it ideal for use in structural work.
In screed flooring, fine, sharp sand is included instead of gravel. This results in a screed mix with a smoother, finer and more tightly packed texture – making it ideal for use as a top layer on a concrete slab floor.
Do concrete and screed look different?
Concrete and screed do look different. The pieces of gravel and stone are visible to the eye in the concrete mix, whereas screed is much finer and smoother, screed has an appearance like hard-packed wet sand that has dried into a solid state.
How To Tell if Screed Is High Quality
To ensure that you use top quality screed, purchase from a BSI certified concrete supplier like Gills Mix. We never compromise on screed standards, and always use premium-quarried aggregates in our screed mix. But you don’t have to take only our word for it – our concrete and aggregates have been independently tested and certified by the BSI, so you’re guaranteed a premium product, every time.
Uses of Floor Screed
Floor Screeding for Professional Flooring Finishe
Using a high-quality screed is crucial to get a good-quality finish for cement floors. Screed helps to provide a nice, level, smooth surface to lay your final floor coverings on top of, such as carpet, tiles, linoleum or wood panels, and in some instances can be left exposed. The durability of screed makes it an excellent choice for flooring finishes, as it protects the concrete slab underneath and easily endures the constant impact of heavy footfall.
Screeding for Underfloor Heating
If you want to keep the cost of your energy bills down while keeping your toes toasty warm, screed is an ideal material to use in between the pipelines of underfloor heating. Screed is an excellent underfloor thermal conductor, meaning that it transports heat rapidly and retains it well, acting as insulation to keep the floor warm for longer and maintain a comfortable temperature in a property.
