Anhydrite screed, also referred to as calcium sulphate screed, is a type of liquid screed commonly used in construction. Here are some benefits of anhydrite screed:
- Excellent self-levelling properties
Anhydrite screeds provide a very smooth and flat surface, ideal for various types of floor finishes, such as tiles, carpet, vinyl and wood. The self-levelling nature simplifies the application process, requiring less labour and time to achieve a uniform surface.
- Compatibility with underfloor heating (UFH)
Anhydrite screeds have high thermal conductivity, making them particularly suitable for use with underfloor heating (UFH) systems. The screed efficiently transfers heat from the pipes or cables to the floor surface. It can fully encapsulate the heating elements, ensuring even heat distribution and reducing the risk of air gaps that can affect performance.
- Reduced thickness
It can be applied in thinner layers compared to traditional cement screeds, typically between 25mm to 40mm. This can save on materials and reduce the overall height of the flooring system, which is beneficial in projects with height constraints.
- Faster drying times
Generally, anhydrite screeds dry faster than traditional cement screeds. The typical drying rate is approximately 1mm per day up to 40mm thickness under optimal conditions, allowing for quicker progression to subsequent construction stages.
- Low shrinkage and cracking
Anhydrite screeds exhibit low shrinkage, which reduces the risk of cracking and curling. This results in a more stable and durable floor over time.
- High flowability
The high flowability of anhydrite screeds allows for rapid and efficient coverage of large areas. This makes it particularly suitable for extensive flooring projects in both residential and commercial settings.
- Improved workability
Anhydrite screeds are easier to pump and handle during application, reducing physical strain on workers and increasing overall efficiency on the job site.
- Environmental benefits
Production of anhydrite binders typically has a lower carbon footprint compared to Portland cement, making anhydrite screeds a more environmentally friendly option.
In summary, anhydrite screed is an excellent choice for a wide range of flooring projects, especially where efficiency, durability, and thermal performance are critical considerations. We offer this service within Nottinghamshire, contact us for more information.
