Polymer chambers. Strongly on the rise

Around 78% of the public sewer network in Germany will need to be renovated in the medium to long term. This raises the question: polymer or concrete? In the past, the choice was mainly in favour of concrete or masonry drainage chambers. Comparing the material properties of concrete chambers with those of polymer chambers, it quickly becomes clear that this was not necessarily the best choice. Polymer solutions are up to 37% less expensive in the long term and are significantly safer, tighter, more resilient and require less maintenance in everyday use. And they also score high marks in terms of sustainability over their entire life cycle of around 100 years.

Mechanical, thermal and chemical advantages

While concrete and stone seem to be unbeatably resistant and hard building materials, this is also their disadvantage: even slight vibrations, e.g. from road traffic, can cause permanent damage. In contrast, an AWASCHACHT made of pure polypropylene absorbs shocks without any problems thanks to its dynamic load-bearing capacity. This is made possible by the high material quality, which also ensures that no cracks or flaking occur.
