Dorfner’s high-quality mineral raw materials are used in many important building materials in the construction industry. The range of applications for Dorfner fillers and sands extends from concrete and aerated concrete to gardening, landscaping and sports facility construction and much more. Dorfner products are also available in well-stocked building materials stores.
Dorfner filler technology for excellent building materials – the applications at a glance:
A key role in concrete Raw materials from Dorfner are an elementary component of modern concrete as an aggregate. Whether liquid concrete, prefabricated parts or concrete-based paving stones: high-quality minerals from our own deposits literally play a supporting role in the construction industry’s all-important artificial stone.
Porous lightweight concrete can only reach its full potential with high-quality raw materials such as fine quartz powders from Dorfner. These give the steam-hardened building material its heat-insulating properties, excellent workability and reliable durability in use – for example in walls.
Dorfner products have proven themselves in gardening and landscaping for decades. For example, refined jointing sands from Dorfner ensure decorative paving joints with a particularly high-quality appearance. Excellent drainage properties, weather resistance and very good workability are a matter of course.
Dorfner is one of the pioneers of infill systems used on modern all-weather tennis courts. But it is not only there that Dorfner products ensure perfect conditions for sport. Dorfner’s high-quality mineral raw materials are the ideal solution for sports and leisure facilities.
Safety for filters All Dorfner raw materials are processed and cleaned in several stages after extraction. This naturally also applies to the high-quality filter sands, which can even be used in highly sensitive treatment plants for drinking water. The high degree of purity of the products ensures that no undesirable substances can be dissolved. In addition, the special properties of Dorfner products for filters facilitate backwashing and allow a long service life.
Many Dorfner products are absolute bestsellers in the building materials trade. They have proven their worth in numerous projects and impress with their consistent quality and superior performance. For professional and home users, the Dorfner trademark on bagged goods – such as quartz sand – is a guarantee of user-friendly building materials that deliver what they promise.
