As a market leader we have defined quality and processing guidelines for our customers and only the precast concrete plants that commit themselves to these standards and can prove it, are allowed to market their manholes with the PREMIUM PRODUCER quality seal.

PREMIUM PRODUCER – that means:

The particular producer certifies, that the Premium Product is produced according to the PREDL company delivery, quality and processing guidelines.
