Here at iMix Concrete, we don’t just supply a wide range of concrete, we also supply a range of screeds – from Gypsol to Cemfloor.
One of the new products in our screed range is Gypsol Flowing Screed, which can be used to create a level, flawless base with ease.
Our experts have shared a complete guide to Gypsol Flowing Screed. Keep reading to find out more about Gypsol Flowing Screed, its benefits and its full scope of use cases.
What is Gypsol Flowing Screed?
Gypsol Flowing Screed is a variety of high performance liquid floor screed.
It consists of a calcium sulphate binder, which is then combined with specific aggregates and water. This mixture makes it unique to traditional screed, which uses a combination of sand and cement.
Once pumped into the required area, Gypsol Flowing Screed is self-smoothing and self-compacting. It sets as a dense, level base, and it forms a smooth, flawless and even floor finish, without requiring manual levelling or any extensive finishing work. Plus, it’s suitable for use across a wide range of construction project types, including timber frame, modular and steel frame projects, amongst others.
Sand & Cement Screed vs Gypsol
Sand & Cement Screed features cement and sand as its binder types, whereas Gypsol Flowing Screed uses calcium sulphate (anhydrite) and aggregates. This gives it several distinctive properties.
While Sand & Cement Screed needs to be mixed on site, then manually laid and levelled, Gypsol Flowing Screed can be pumped into the required area, then its self-smoothing and self-compacting properties mean that minimal further manual work is required.
What’s more, while Sand & Cement Screed has a minimum thickness of around 75mm, Gypsol can achieve much thinner layers, often achieving 25–50 mm. This makes Gypsol much less labour intensive, with a faster finishing time, drying time and a rapid installation process. It is also much more suited for use in large bays (up to ~1000 m²), whereas Sand & Cement Screed is usually limited to small bays, in order to minimise the risk of cracking.
Plus, Gypsol has a lower risk of shrinkage and cracking, and offers significantly improved thermal conductivity.
What are the benefits of Gypsol Flowing Screed?
- Fast and efficient installation
- Rapid drying times
- Self-levelling
- Self-compacting
- Smooth and even finish
- Pumpable
- Reduced labour and time requirements for installation
- Flexibility with section thickness
- High durability and strength
- High resistance to shrinking and cracking
- Improved thermal performance and energy efficiency
- Great compatibility with underfloor heating
- Reduced environmental impact, as the levels of embodied carbon in the material are much lower (as the binder used is derived from a by-product of industry)
What are the different types of Gypsol Flowing Screed?
Depending on your project requirements, Gypsol Flowing Screed is available in a wide range of product types. This ensures the perfect fit for all use cases.

Understanding a Layer and Carbon Comparison (Sand & Cement vs Gypsol)
Let’s go into a more detailed comparison of the layer and carbon footprint, between Sand & Cement vs Gypsol.
Thickness – Traditional Sand & Cement screed can only be installed at higher thicknesses (typically 70-75 mm is required at the minimum, to ensure sufficient stability). Gypsol Flowing Screed can be installed at far less thickness, at a minimum of 25 mm for bonded layers, 30 mm for unbonded, and 35-50 mm for floating screeds.
Weight and floor-load – As Gypsol Flowing Screed can be installed in thinner layers, this also reduces the overall weight and structural load. This is a very valuable benefit in projects that are using lightweight or mixed-frame structures, and can help to simplify structural requirements.
Carbon footprint – Gypsol Flowing Screed uses an anhydrite binder. This is derived from industrial by-products, as such, its manufacture requires minimal energy and its level of embodied carbon is significantly lower than cement. Plus, Gypsol Flowing Screed can be installed in much thinner layers, further reducing the environmental impact.
