When flooding gets back, so does the traffic. And since Valenzuela is the northern gateway to Metro Manila, the traffic is already bad. If the place gets flooded, so much more. Waterproofing places is one of the ways to keep the roads clear and also by doing this in your house, you do this also for the community as you save water and help redirect the flow of water towards its proper place. Most of all, you also help ease the traffic as not all cars are equipped to handle heavy flooding.
