Crushed sandstone
This aggregate - crushed sandstone comes of self-resources. It is suitable for companies, which are concerned with building preparation, construction of roads, drainage systems and similar activities.
We are offering this material under advantageous conditions from location in economical distance of the capital.
Application possibilities
| Fraction 0 - 20 mm | Fine to midrange sandstone with sharp-edged fragments, relatively hard. Material in general good usable always, when can be used sand with rubble, i.e. especially for backfills and shroudings or as a material to mounds. After moistening is this material good compressable. |
|---|---|
| Fraction 20 - 40 mm | Sharp-edged fragments relatively hard. Suitable use for drain ditches, areal drains building, eventually as protection against frost. |
| Fraction 20 - 80 mm | Usage for drainage elements building after mechanical grinding, eventually could be used by building of mound toe drain. |
Fractions 0 - 20 mm and 20 - 40 mm can be used as stiffening level by building of stratified (sandwich) mounds.
Supplied also as unsorted aggregate in fraction 0 - 500 mm.
