Filter Sand

Filter sand is a specially graded type of natural sand. It is ideally suited for infiltration and water passage in geotechnical engineering, such as in drilling for geothermal heat, along drill pipes in geotechnical engineering.

This is due to its specific grain composition, which gives filter sand a purifying effect when dirty water flows through. In addition, filter sand has a permanent draining effect for rapid drainage of clean and dirty water. Filter and drainage sand is clean and dust-free.

Filter sand is available in bulk, loose fill, big bags and 25-kg bags.

For filter applications, the fine grading 0/1 mm or 1/2 mm is often used.
For drainage, the coarser grades of sand can be used, 1/3 mm or 0/4 mm.

In drilling for geothermal heat and infiltration. Combined with filter gravel, it forms a water purifying package.

In park and landscape design at ponds, banks, wadis, etc.

Filter sand is used in road construction particularly under permeable pavement.
