Floor construction manual

  1. Place the Staenis grid and adjust it to the correct height with a screwdriver. Use sawn wooden blocks under the Staenis legs to adjust higher.
  2. Stick all feet to the surface with PU foam, so that the height adjustment remains correct after adjustment.
  3. Pour the load-bearing levelling granules or aerated concrete into the grating and level it with a screed iron on the top of the Staenis grating.
  4. Place on this at least an OSB of 22 mm thickness. Screw the wooden plate into the battens of the Staenis grid. If necessary, apply double plating for extra strength.
  5. With a single plating on the load-bearing fillers, the 22mm OSB will still spring slightly. With a double plating (12mm + 18mm) the deflection is completely gone. (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 needs a thicker OSB, a thick floor finish can be combined with the minimum OSB thickness for this floor construction.
  7. Be vigilant: if the wooden grating springs when you step on it, the surface can gradually bend under the weight of the installed Staenis grating and the aerated concrete granules. It is recommended to first stabilize the substrate and possibly opt for a lighter alternative, such as a non-tilable insulating screed.

Aerated concrete leveling granules for dry floor

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

Aerated concrete leveling granules can only be installed in combination with the Staenis grid, with an OSB plate or Fermacell floor plate above it.

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

The aerated concrete leveling granules are load-bearing, so you do not need to install 8 extra legs per square meter.
