What is a basin?

The base tub is designed to protect the basement if it falls below ground water level. It is made of waterproof concrete. Also called waterproofing bath.  Its advantage is that it protects cellars, basements and underground spaces from damage due to the ingress of moisture or groundwater. Waterproof concrete on the base tub is designed to withstand pressure water. The design of this concrete mix must be very careful. 

The bath has been used in Central Europe and Germany for decades. The minimum thickness of the concrete is 250 mm for walls and slabs. This is a proven value for years. The key element is the degree of reinforcement, which will reduce the potential for cracks. The bathtub offers the ideal tension distribution in the base spill . The designer must first determine one of the five classes of indoor environment requirements, depending on the groundwater pressure classes.
