Stone filling & lightweight concrete

Stone filling & lightweight concrete

The stone filling serves to improve the insulation properties and thus effectively contributes to reducing the heating or cooling energy costs otherwise necessary in the building. Various insulating materials can be inserted into the stone holes, with mineral materials not only providing good insulating properties but also improving fire protection. Added to this is the simple and efficient recyclability at the end of the building’s lifespan, including reuse as a new raw material.

In lightweight concrete, additives such as lightweight granules, foam particles, expanded clay, or other components ensure a significant reduction in product weight. This means that 250 kg/m³ or less can be achieved for lightweight concrete or “ultra-lightweight concrete”. The particular advantage of these products is that they do not need to be autoclaved to harden. This not only saves the high energy costs, but also allows the production system to be smaller, which is noticeably reflected in the reduced hall and handling costs. The production of large wall elements is just as possible as that of bricks.

The choice between stone infill and lightweight concrete depends on the specific requirements of a construction project. Stone filling refers to the introduction of insulating material into the stone holes (e.g.: mineral foams with a density of approx. 55 kg/m³), while lightweight concrete or ultra-lightweight concrete has been developed specifically for applications requiring lower weight and improved Thermal insulation is required.

Your Advantages

Lightweight concrete products and stone backfill have the following advantages:

Product examples:

When producing prefabricated walls in the production plant, ultra-lightweight concrete is placed as insulating foam between the two external formwork/wall segments. This also creates a firm connection between the 3 segments, which at the same time results in significant weight savings for truck transport.

Yes, our system concepts give you the opportunity to produce the product in different raw densities on site. This means you save transport costs and react flexibly to changing applications or requirements.

By using lightweight wall systems, the weight per floor is noticeably reduced. This enables a slimmer design and reduced space requirements. At the same time, by using prefabricated modules or producing the walls on site by foaming on the construction site, corresponding transport costs can be saved and construction times can be noticeably reduced.
