2K grouting system in action
Framework agreement with Munich Airport

How can joints on airfield surfaces be filled efficiently, using minimal material and ensuring a permanent seal? And, above all, in compliance with the requirements of the Water Resources Act? These were precisely the questions raised by the framework contract for concrete and joint rehabilitation at Munich Airport. The solution? The development of a bespoke two-component grouting system.

Over a period of four years, POSSEHL Spezialbau is responsible for the maintenance of the airside areas at Munich Airport, including joint rehabilitation using the cold-pouring method. Cold pouring was a key requirement for the contract award. To meet this requirement – and thus minimise disruption to flight operations and avoid closure periods – a new two-component grouting system was needed. 

Bespoke two-component grouting system

No sooner said than done: we have developed a new bespoke two-component potting system specifically for Munich, which is now in daily use. 

Two-component casting systems are used to precisely dispense two liquid components – a base and a hardener component – mix them homogeneously and apply them to a component, a surface or into a joint. 

As early as 2024, the team at the Bavaria branch gained initial experience with a two-component system from the Netherlands. This system had the advantage that the mixing ratio could be individually programmed. This allows different materials, such as SABA Sealer Field or SABA Sealer Fast, to be processed flexibly.

The new 2K grouting system offers numerous advantages. One of the most important is that the required pump pressure is generated electrically. This means we can do without the large compressor that would otherwise be necessary. This significantly simplifies handling and reduces the logistical effort on site. Furthermore, up to 1,000 metres of prepared joint chambers can be processed per hour. The maximum material output is 5.1 litres per minute. 

However, the development is not yet complete. The plan is to mount the system on a self-propelled trailer in future, so that it can operate independently of a tractor unit. We look forward to driving the development forward and continuously improving the system in practice
