The rounded shape of our silica sand and the consistent colour are highly valued in the construction industry. These properties and the continuous particle size distribution of the sand enables a high degree of compaction to be achieved for filling and backfilling. Our silica sand is perfect for producing high-quality building materials, such as concrete products, ready-mix concrete, mortar, paving stones, plaster sand, stopping sand and asphalt production. Screed sand is also used as drainage material or to create a frost protection layer.
Our Rhine gravel is a natural building material that can be used for residential building as well as for paving and horticulture. The properties of natural stones make them ideal for decorating your garden. Rhine gravel obtains its round granulation and appealing smooth surface from its origin from natural bodies of water and rivers. This colourful round gravel has many applications. As pebbles it is used as concrete aggregate, road construction material or filler for building and industrial applications. The use of Rhine gravel is becoming increasingly popular in roof greening, as it protects the roof seal from damaging influences, such as UV radiation, extreme temperatures and mechanical damage, which extends its useful life.
The gravels and sands provided by WOLFF & MÜLLER Quarzwerke GmbH fulfil the DIN EN requirements for concrete (12620), mortar (13139) and asphalt (13043), and are subject to voluntary quality control, making them ideal for use as a construction aggregate for the building industry.
