Basalt

Basalt – primary rock from the earth’s interior

Basalt is one of the most widespread rocks on land and at the bottom of the oceans. You can recognize basalt by a pattern of small gray, dark brown and black splashes of color. As the earth's primary rock, basalt has existed for several million years. Basalt is mainly used as bulk material for the substructure of roads and railway tracks. To this day, the ancient rock is also popular in gardening and landscaping.

Properties of basalt: Indispensable qualities for construction

Basalt features an impressive combination of properties that make it a preferred material in the construction industry. Its high compressive strength, resistance to abrasion and chemicals, and low water absorption are just a few examples. The basalt's uniform texture and color contribute to its aesthetic appeal, while its natural availability and sustainability underline the environmental responsibility of the construction industry. Basalt's unique properties make it an essential building material that supports the stability, durability and environmental friendliness of construction projects around the world.

A versatile filler for concrete

Basalt is a fascinating rock that is widely used in the construction industry due to its excellent properties as a filler for concrete.
Adding basalt as a filler to concrete mixes brings a number of benefits. Basalt is highly resistant to chemical corrosion and wear, which significantly improves the durability of concrete. In addition, basalt as a filler helps to reduce thermal distortion and improves the strength properties of concrete. This makes basalt an excellent choice for constructing bridges, buildings and other demanding infrastructure projects.

Filler for asphalt

Basalt also plays a crucial role in asphalt construction. As a filler, it improves the durability of the asphalt pavement and increases its load-bearing capacity. Basalt asphalt is known for its resistance to temperature changes and heavy traffic. This makes it ideal for roads, highways and airport runways where resilience and durability are of utmost importance.

Environmentally friendly option

Basalt as a filler is popular not only because of its technical advantages, but also because of its environmental friendliness. It is a naturally occurring rock that is extracted in quarries and therefore has less environmental impact than other fillers. This contributes to the sustainability of construction projects.

In the construction industry, basalt has a long history and a promising future as a filler for concrete and asphalt. Its outstanding durability, strength and environmental performance make it a preferred choice for builders and engineers who value quality and sustainability.

Our basalt quarry

The natural raw material basalt is not only used today in many different areas of application. The Romans and the Celts already used basalt. For example, basalt was used as paving stone for the construction of the Via Appia from Rome to Brindisi. High-quality millstones and memorial stones were also made from basalt. The use of the raw material began around 7,000 years ago when it was discovered that the positive properties of the natural rock allow it to be used in a variety of ways. And the basalt quarry is still very important today, because basalt is still a frequently used material.

It is assumed that each basalt quarry in our region was formed up to seventy million years ago. The origin is due to volcanic activity in underground streams and lakes formed by lava. Our basalt quarry is located on the edge of the Westerwald in close proximity to the border triangle of North Rhine-Westphalia, Rhineland-Palatinate and Hesse. We offer you the natural raw material in our on-site basalt quarry in various forms of processing, for example as basalt stones, basalt gravel or basalt chippings.
