Element wall (double wall)

Today, modern reinforced concrete technology is a highly developed and high-performance construction technology. Concrete is used in a wide variety of qualities for various requirements. The composition of cement, aggregate, water, admixtures and air can achieve a wide variety of properties. Prefabricated and semi-prefabricated elements such as double-walled elements are playing an increasingly important role in current construction activity. The elements prefabricated in the factory lead to significantly shorter construction times and increase precision.

More about element walls In

addition to conventional cast-in-place concrete walls, element walls are increasingly being used for the construction of reinforced concrete walls, as they require a shorter construction time, can be built without formwork and have a high surface quality that can remain visible depending on the requirements. A special form of element walls is the thermal wall, which is manufactured at the factory with core insulation within the two precast shells.

Notes on the planning

element walls and in-situ concrete walls in comparison: Element walls (double walls) can be erected in a significantly shorter construction time compared to conventional in-situ concrete walls. In addition, no formwork is required on site, as the approx. 6 cm thick precast shells function as lost formwork. The joints between the elements of the double wall are filled, as are smaller cavities. After that, the wall is ready to paint. The prerequisite is careful planning and the necessary lead time for the production of the semi-finished elements.

In terms of pure construction costs, element walls are somewhat more expensive than in-situ concrete walls. From the following points of view, element walls are nevertheless more economical than in-situ concrete walls:

• Surface quality: if a high-quality use of the rooms behind them is required, element walls can be economical because plastering of the inner wall surfaces can be omitted.
• Construction time: A construction time shortened by prefabricated walls can bring economic advantages to a project in individual cases.
• Formwork: Prefabricated walls can also be erected if the executing construction company is unable to use large-area formwork for the construction of in-situ concrete walls, either permanently or temporarily. The prefabricated shells of the panel walls then take over the task of formwork.
