In the recent period, we have been working on three parking garages on Fregelaan in Amsterdam. We have resolved water leakages, performed concrete repairs, and provided the ramps with a new wear layer. First, we addressed the leaks caused by the overhead roof gardens and walkways. We did this by incorporating all connections and details with a waterproof membrane. This involved the connection between the roof garden and the upstand, the joints of the coping stones, and the joints of the walkways and stairs.
