An anhydrite floor is an ideal surface for various types of floor finishes, such as tiles, laminate, parquet, carpet or PVC. It is therefore also ideal as a screed floor for various commercial and industrial applications.

On this page you can read everything you need to know about anhydrite floors, the advantages and disadvantages, the properties, the applications and the costs. We will also tell you why it is best to have an anhydrite floor installed by ICM Projects.

What is an anhydrite floor?

An anhydrite floor, also known as anhydrite screed, is a floor type that consists of a mixture of anhydrite, sand and water. It is poured in liquid form onto the supporting floor and, after curing, forms an even and flat base for further floor finishes.

Anhydrite floors are also called anhydrite cast floors, because the liquid mixture is poured over the supporting floor and levels itself. This mixture is applied at a thickness of approximately 30 to 50 millimeters, depending on the application and any additional wishes such as underfloor heating.

What are the advantages of an anhydrite floor?

An anhydrite floor has several advantages over other types of screed floors, such as cement screed floors. Below we have listed the most important benefits:

  • Fast drying: an anhydrite floor dries faster than traditional screed floors, making the installation process more efficient.
  • Self-levelling: Anhydrite has the property of leveling itself, which ensures a smooth and even surface.
  • Excellent heat conductor: ideal for underfloor heating systems as anhydrite disperses heat quickly.
  • Environmentally friendly: anhydrite is produced with natural raw materials and has a low environmental impact.

What are the disadvantages of an anhydrite floor?

In addition to the many advantages, there are also some disadvantages that you should consider before choosing an anhydrite screed:

  • Less suitable for damp areas: anhydrite can be sensitive to moisture, which is why it is less suitable for bathrooms, for example.
  • Impact sensitive: anhydrite is more vulnerable to impacts and pressure points than some other floor types.
  • Professional installation required: Installing an anhydrite floor requires craftsmanship and experience.

What are the properties of an anhydrite floor?

An anhydrite floor has a number of specific properties that distinguish it from other types of screed floors. Below we list the most important features:

On which surfaces can an anhydrite screed be applied?

An anhydrite screed can be applied to various load-bearing surfaces. The most common types of substrates on which an anhydrite screed can be applied are:

  • Concrete floor
  • Wooden floor
  • Steel floor

It is very important that the subsurface meets a number of conditions. This is how the surface should be:

  • To be firm and stable;
  • Be dry and clean;
  • Be smooth and flat;
  • Provided with an adhesive primer.

For which finishing floors is an anhydrite floor the perfect basis?

Anhydrite floors form a flat base on which various floor finishes can be placed. For example, an anhydrite screed is flatter than, for example, a sand-cement screed and is an ideal surface for, among other things:

  • PVC floors
  • Cast floors
  • Carpet floor covering
  • Linoleum
  • Marmoleum

In addition to the above floor finishes, anhydrite screed floors can also serve as a substrate for other floor types. Our experts can advise you on this.

How long does an anhydrite floor need to dry?

An anhydrite floor usually has a drying time of 24 hours per centimeter of thickness. However, this can vary depending on factors such as temperature and humidity. It is important to carefully observe the drying time before applying further floor finishes.

What are the costs of an anhydrite floor?

The costs of an anhydrite floor vary between €10 and €40 per m2. Depending on factors such as the surface, thickness, condition of the surface and any additional treatments, prices may vary. For an accurate quote, you can request a quote without obligation.

How strong is an anhydrite floor?

An anhydrite floor has a high compressive strength and can bear heavy loads. The exact strength depends on the composition and thickness of the floor. In most cases, an anhydrite floor is suitable for normal use in commercial and industrial spaces.
