Stone flour 0-8
Stone flour is a very fine material that is extracted when crushing rocks and can be used for both tiling and ground adjustment, hardening or leveling of yards and footpaths. Stone flour 0-8 is a fine type of setting sand that can be used when laying paving stones, tiles and paving stones. The fraction 0-8 makes the bed very even and incredibly packed, which leads to a stable stone setting. Stone flour can be used on both walkable and drivable surfaces. Stone flour is available in several different fractions on the market, but we at Stenbolaget have chosen to work with 0-8 as this provides better drainage than, for example, 0-4. However, Macadam/Flis 2-6 has a much better draining effect than just stone flour and makes it a more recommended setting material for stone setting in general.
The stone flour forms a bed that is laid in an approx. 3 cm thick layer on top of the bearing layer/rock crusher itself. The ground stone is then mounted with a rubber mallet and driven into the bed for as stable an installation as possible.
With a bed thickness of about 3 cm, 1000 kg is enough for about 20 square meters.
Stone flour has the advantage that ants and other vermin do not thrive in it as well as in other sand and silt. The tunnels become more difficult to dig and the surface more unpleasant to live in.
Stone flour is also used as leveling under the base stones when building walls and in some cases as stable framing and adjustment when setting curbstones.
When installing natural stone tiles and moisture-sensitive stone, we really recommend that you install Macadam/Flis 2-6 instead, as this gives an even better draining effect. An effect you need to avoid moisture migration in tiles that usually happens during the colder and more humid autumn season.
