Schalungslinien

Schalungslinien, also known as formwork lines or screed lines in English, are temporary guides used in construction, particularly in concrete work. Their primary function is to define the precise location and height of a concrete surface, such as a floor slab or a wall. These lines are typically established by skilled tradespeople, often referred to as screeders or formworkers, using surveying equipment or simple leveling tools.

The creation of schalungslinien involves setting out points or lines that represent the finished level of the concrete. This can be achieved by using wooden battens, metal profiles, or even screwdrivers driven into the sub-base. The height of these lines is meticulously adjusted to ensure that when concrete is poured and leveled off against them, the final surface will be at the intended elevation and possess the desired slope or flatness.

These lines are crucial for achieving accurate and consistent concrete finishes, preventing costly overruns or underspending of materials. They are particularly important in large areas where maintaining a uniform level is challenging. After the concrete has hardened and achieved sufficient strength, the schalungslinien are removed, leaving behind a clean edge and the perfectly formed concrete surface. The removal process is done carefully to avoid damaging the newly cast concrete.
