OUR RC BUILDING MATERIALS

Our RC materials are subject to constant quality and quality controls and thus also meet the highest requirements that are made in classified road construction in all construction classes. Their composition and all necessary quality parameters are regulated in the technical guidelines for recycled building materials. Compliance with these regulations is ensured with in-house production control systems and external tests by independent test laboratories.

Our promise of quality

SECURITY - SIGNED AND SEALED

We consistently apply quality assurance measures at all times, which ensure the problem-free installation of our RC materials and bindingly certify their properties. After all, the most important prerequisites for using recycled building materials are their equivalence in comparison to building materials made from primary raw materials and their environmental compatibility.

In the service of the environment

OUR SPECIALTY: BUILDING RUBBLE RECYCLING

Felix Höltken GmbH, a company in the STEAG Group, has been operating a stationary processing plant for the production of mineral building materials in Cologne since 1990. From concrete, asphalt, masonry and mineral rubble, we produce high-quality, tested recycled building materials for use in road construction, earthworks and civil engineering. Our first-class products are an economical alternative to natural stone, whose resources are conserved through the use of recycled material.

Conserve natural products

WE SAVE RESOURCES - NOT QUALITY!

Used building materials that accumulate as rubble from concrete and mortar, gravel, sand and chippings, bricks, sand-lime bricks and ceramics, as road excavation or excavated soil form the raw materials for our high-quality RC materials during the dismantling, conversion or renovation of structures. By reprocessing them, natural raw material resources can be conserved and kept longer available for the future.
