Conclusion and recommendation

From a technical, economical and normative perspective, the following core points speak in favour of specifying Langmatz polycarbonate manholes as a standard solution:

• Standard conformity and system certification

Complete system-based evidence in accordance with DIN EN 124, load class D400, with ETA and CE certification for the entire manhole system, not just for the cover (see page 14).

• Load-bearing strength and durability

3D ribFrame® technology guarantees corresponding load transfer and excellent stability in compliance with the expected volume of traffic, even under repetitive traffic loading and temperature changes.

• Significantly reduced weight and installation time

Approx. 75–80 % lighter than similarly sized concrete manholes – lower construction, transport, and equipment costs, higher productivity.

• Higher profitability along the life-cycle

Langmatz polycarbonate manholes offer economical benefits compared to concrete manholes in relation to their Total Cost of Ownership.

• Functional improvement for cable and telecommunications networks

Well-thought-out system-based details (predetermined breaking points, Vario Modules, height adjustment) shorten installation times and increase the operational reliability of the networks, among other things.

• Sustainability and resource conservation

Lower mass, high resistance, and recyclability contribute to measurable environmental benefits that coincide with the aims of modern infrastructure policy (climate protection, efficient use of resources).
