Pfuhler-Schlitzrinnen-System Z

Slot units with general building approval Z-74.4-46 dated 26 August 2009

Our reinforced concrete slot units are produced in precisely dimensioned steel formwork. The concrete recipe used has been tested using the test program of the Deutsche Institut für Bautechnik with which it is deposited. Rebar steel BSt 500S/M is installed as reinforcement. 

We use C40/50 concrete for our reinforced concrete "Pfuhler Rinne" slot units. Its composition, manufacture and use correspond to a concrete to DIN EN 206-1 and DIN 1045-2. 

It is suitable for the following exposure classes:

  • XD3 – Reinforcement corrosion induced by chlorides, other than from seawater, environment is cyclically wet and dry
  • XF4 – Frost attack with or without anti-freeze, environment with high water saturation and anti-freeze
  • XA2 - Concrete corrosion due to chemical attack, moderately aggressive chemical environment, (except chemical attack by sulphate > 600 mg/l – here we can produce special slot units using cement with high sulphate resistance)

Due to the high concrete strength (C40/50) in conjunction with the high tensile strength of the reinforcing steel used, reinforced concrete slot units can safely withstand the static and dynamic loads that occur. 

Constant, comprehensive quality assurance according to the general building approval specifications, consisting of self-monitoring and external monitoring ensures a consistently high quality standard.
