Levelling granules

Information

Load-bearing fillers such as cellular concrete granules are ideal for creating a dry floor. In this situation, the StaenisGrid serves as a wooden joist system, placed on a pressure-resistant and dry concrete substrate. The floor structure is demountable and can be reused without waste.

Advantages

Achieve a perfect end result without experience
Directly boardable with double staggered Durelis or OSB wood panels
Afterwards, it can be directly covered with many types of floor coverings.
Lightweight, fire-resistant and sound-absorbing floor structure

Very fast, light, and dry installation
Possibility to insulate your low floor construction over the entire thickness.
Spreading floor work over several days (no stress during installation)
Circular floor construction with dry ecological & sustainable infill materials

Levelling granules

1. Place the StaenisGrid and adjust it to the correct height using a screwdriver. If necessary, use Staenis extension legs or sawn wooden blocks under the Staenis legs to adjust it to a higher level. 2. Glue all legs to the substrate with PU foam; this way, the height adjustment remains correct after leveling. 3. Pour the load-bearing leveling granules or aerated concrete into the grid and level them with a screed bar on top of the StaenisGrid. Compact these granules for better stability. 4. Place at least a 22 mm thick OSB board on this. Screw the wooden board into the slats of the StaenisGrid. Apply double boarding if necessary for extra strength. 5. With a single sheathing on the load-bearing infill materials, the 22mm OSB will still flex slightly. With double sheathing (12mm + 18mm), the deflection is completely eliminated. (1 ton/m² compressive strength) 6. Tip: Depending on the type of floor finish, you choose the thickness of the OSB. A thin floor finish requires a thicker OSB, while a thick floor finish can be combined with the minimum OSB thickness for this floor structure. 7. Tip: To prevent loose granules from rolling away or flowing through holes and cracks, it is advisable to carefully seal all openings in the concrete substrate beforehand with PU foam or mortar. 8. Permitted floor coverings: floating floor coverings such as multilayer parquet, laminate, cork, carpet, and vinyl. Always follow the installation instructions of both the floor covering manufacturer and the store where the purchase was made.

Cellular concrete leveling granules for dry screed

Aerated concrete leveling granules are a cheaper alternative to the standard leveling granules from, for example, Fermacell.

Cellular concrete leveling granules can only be installed in combination with the StaenisGrid, with an OSB board or Fermacell floor panel on top.

The cellular concrete leveling granules in bags are easy to transport and make it possible to level your floor dry by yourself.

The cellular concrete leveling granules are load-bearing, so you do not need to place 8 extra supports per square meter.
