Why Is Sand Important When Installing Pavers?

The coarse, jagged nature of bedding sand is an integral component in paver installation.

What is traditional screed, what is stabilised sand, what is concrete?

Screed, stabilised sand and concrete all contain sand, cement and water. Each of these mixtures is used in the installation of floors and pavements. But what's the difference? What is screed, what is stabilised screed and what is concrete? And for which applications do you use them best? A crash course.

What is stabilised sand?

You've probably heard about stabilised sand, but what exactly is it? This mixture consists of cement, sand and some water. Because stabilised sand is quite water-permeable, it often serves as an underlayer for materials that are installed outside, such as clinkers, natural stone tiles, edging and paving.

What is traditional screed?

If you have never built or renovated before, you may be wondering: what is screed? A screed forms the strong and indispensable basis for almost all floor finishes, such as floor tiles, laminate, parquet and carpet. Furthermore, a screed (also called stabilised sand) protects the utility pipes and ensures a long life for your floor.

Difference 1: a different ratio of sand, cement and concrete

Don't be fooled: if you don't know the difference between screed and stabilised sand, don't worry. After all, screed and stabilised sand have a lot in common. They consist of the same raw materials: sand, cement and water. So what exactly is the difference between stabilised sand and ordinary screed? To begin with, the proportions used vary.

Difference 2: stabilised sand allows water to pass through

A second important difference between stabilised sand and ordinary screed is the water permeability. Stabilised sand allows water to pass much more easily. That is why stabilised sand is often used as a foundation for materials that are laid outside: natural stone terrace tiles, pavers for a driveway, footpaths and so on.

Difference 3: screed has a longer drying time

Screed is a moister mixture than stabilised sand. As a result, the drying time of ordinary screed is much longer than that of stabilised sand, although it also depends on other factors such as the thickness of the layer, the ambient temperature and the sand used.

Difference 4: a different approach to producing it
