AWADUKT PP pipes. No cracks, no fractures
Pipes made of pure, filler-free polypropylene (PP), such as AWADUKT PP pipes, achieve the best values for impact resistance, dynamic load-bearing capacity and resistance to notches compared to filled pipes. They are 40 times more impact-resistant than stoneware or concrete and up to 250 times more resilient than polymer pipes with mineral additives. This is the result of an investigation by the independent expert Dr Fischer. Cracks and fractures, which often occur with rigid pipe systems made of stoneware or concrete, are virtually impossible with pure polypropylene.
The REHAU solution
In direct comparison, AWADUKT sewer pipe system is significantly better than other systems thanks to the solid-wall, filler-free design made from high quality polypropylene. There are more differences between polymers than you might expect. For example, there are polymer systems on the market that contain up to 40 % mineral additives. This is not without consequences for the dynamic load capacity of the systems.
In the past, civil engineering was suspended in winter – for obvious reasons. Today, snow and freezing cold do not stop construction activity: developers urge builders to hurry, construction companies do not receive "bad weather pay" and local authorities set tight timeframes for the realisation of construction projects because time is money. It's good to know that high-quality, modern building materials can also be used for civil engineering work below freezing – provided the right product is chosen. Because the material makes all the difference! Printed "ice crystals" are no guarantee for good impact resistance of the pipe systems in the cold, and PP, which is a highly impact-resistant material, becomes as brittle as glass at low temperatures when mineral fillers are added. So not all types of PP are the same. You can rely on the high quality of AWADUKT PP in accordance with DIN EN 1852. The original from REHAU made of high-impact PP, free of fillers and reinforcing materials, also impresses on winter construction sites.
