Products Used
When leaks were noticed in one of the Metro’s underground parking garages, they contacted Penetron for a solution. Working together with MBRACE, the project contractor, Penetron Hellas applied a crystalline repair solution that included PENETRON INJECT, PENEPLUG and PENETRON to seal leaks in the cracks and joints of the concrete. The project was successfully completed, eliminating any water penetration into the underground garage.
