Lava stone

The melt in the bowels of the earth is known as Magma. When Magma surfaces in the event of a volcanic eruption, this material is called Lava. In the mining area of the Eifel, we find the Lava being a loose, porous and raw-surface natural resource. The gross density varies between 1.5 and 1.9 g/cm³. Depending on its porousness of 20 – 50%, the loose bulk weight measures between 800 and 1400 g/l.

The conditions at eruption defined the grading and the porousness of the Lava. Not only explosive sequences formed the Lava. Geologists also see fumigation and cooling rate to have shaped the Lava we work with today. In the quarries, lava slag and lava sand are to be found in alternating sequences. Here, these layers can be interrupted by basalt inclusions. Hence, the color of the material can vary between grey-black and red-brown; while the color does not allow for interpretations of physical characteristics.

Lava is frost-proof and weather-resistant while showing hardly any chemical reactions. With SiO2 of 44% and AL2O3 of 12%, our porolith-Lava belongs to basalt materials. The density, porousness and the light weight makes it a high-quality resource for various industries.
The rough surface is an important characteristic in acoustic absorption. Further, the resistance against de-icing salts allows an application in gabion structures.  The surface volume enables filtrations in different industries.
