Non-adhesive screed
Screed floor construction 1 - Choose a different floor structure
4.5 to 9 cm - ground floor, basement, ... - with concrete slab as substrate - tiles, multi-layer parquet, laminate, cork, carpet and vinyl
Information
A non-adhesive screed is a screed that is separated from the supporting floor by a separating layer/foil. The screed therefore does not adhere anywhere to the supporting floor.
This foil offers the floor extra protection against moisture infiltration (rising damp).
This screed is always reinforced with the Staenis grid or reinforcement net.
To absorb expansion and contraction, edge insulation of at least 0.5 cm is placed at the edges of the screed.
Benefits
- Achieving a perfect end result without any experience
- Compartment of the screed = crack-free screed
- Replaces an uncoupling mat = savings of an average of 30 euros/m²
- Replaces the steel reinforcement mesh = savings of an average of 3 euros/m²
- No expansion joints needed in the screed = savings of an average of 3 euros/linear metre
- Spread screed work over several days (no stress during installation)
- Much faster start-up of underfloor heating possible = faster construction process
- No dishing/cupping of the screed = perfectly flat screed

We deliver screed in a silo to your home (only in Belgium)
By simply pressing a button on the silo, you can prepare fresh sand cement screed at a rate of 3 m³/h and this without time pressure to process the large amount of sand cement screed.
There are 2 separate compartments in the silo. 1 part filled with sand (0/4-0/7mm) and the other part filled with dry cement (250kg/m³). These are only mixed with water at the moment you wish.
The big advantage of this is that you can make fresh sand cement screed at your own pace and for a few weeks.
We deliver screed to your home in bags
Fast: Fast-drying, fiber-reinforced screed with only 2/3 of the weight compared to traditional screed. This makes the work considerably less difficult when you work with bagged material instead of traditional screed. Ideal for applying an adhesive screed screed floor or for small spaces, both indoors and outdoors. This Fast screed is easily spreadable, allowing you to achieve a flat finish more quickly.
We deliver insulation screed in bags to your home
The insulation screed is ready-made with new EPS pearls, mixed with cement, water and specific patented additives.
The EPS pearls have a special small diameter of 2mm-6mm, in order to obtain an even flatter result with the Staenis grid.
The insulating screed in bags is easy to transport and makes it possible to insulate your floor yourself.
This non-tilable insulation screed can be used as an insulating infill in the Staenis grid, single or double clad with at least 18 mm OSB. But also as an insulating filling layer, with a screed above it.
