The lower mainland is peppered with buildings that have been constructed atop a concrete parkade structure. More often than not, the parkade extends beyond the footprint of the building and has been waterproofed with an improperly applied, black, cheap, thin, liquid waterproofing membrane and covered with soil. In some instances removal of the soil to address leakage would bankrupt the Owners of the building. Is it worth it to do so? Will the leakage corrode the reinforcing steel of the slab?
