Background & policy context: 

There was detected a need to ensure the safety of traffic by the improved horizontal geometry of the surface. The idea of a new waterproofing solution based on the concept of using channels in the insulating roof paper, which, however, does not correspond to the conditions of the road surface, due to the very high mechanical loads. The new waterproofing will have a minimal risk of blistering the pavement of bridges.


The aim of the project is to develop an innovative waterproofing labyrinth designed for applications in civil engineering.

Key Results: 

The results of experimental and FEM simulation carried out by the WUT within the consortium have been:

  • a scientific confirmation of the possibility of safe use the labyrinth waterproofing system in communication infrastructures;
  • knowledge and systematization of the conditions and mechanisms leading to the destruction of waterproofing systems due to the formation of bubbles, which will allow verification of the conditions for the implementation of effective insulation;
  • the development of the method of testing of labyrinth waterproofing insulation usability for use on objects of communication infrastructures (including minimization the risk of blistering waterproofing applied on road surfaces).

The final result of the project has been the implementation of a new product by an industrial partner.
