Products

Unshaped products (selection).

In our constant efforts to intensify customer services and improve products, we have developed innovative refractory concrete grades. These refractory concretes are state-of-the-art products that fulfill all the demands of processing and application behaviour. To ensure a long service life – even under the harshest conditions – it is essential that the concretes are installed correctly. For this end, our bricklaying experts are available to provide on-site technical assistance and supervision during installation.
Production of our refractory concretes meets the tight specifications of ISO 9001 and 14001.

Our product range covers the following types:
• regular-cement castables (RCC)
• medium-cement castables (MCC)
• low-cement castables (LCC)
• self-flowing castables
• dry-gunning concretes
• wet-gunning concretes
• insulating concretes
• prefabricated components
