Procon: the concept for economically efficient construction

Procon is a sophisticated concept in which the required stripping pressure strength is achieved within an agreed number of hours without the use of forced heat systems. On the basis of "Method weighted maturity" and an internal monitoring system, calibration graphs show that stripping can take place on a daily basis. An optimal construction process without the use of external heat sources for a responsible and sustainable end product.

This innovation has been successfully applied in a large number of building projects and makes it possible to realise tunnel forming projects all year round without heating costs. Procon is a serious and responsible option in inner-city projects or projects where the use of propane or natural gas is not possible or legally permitted.
