hi all, water has been seeping into my walls whenever there's heavy rain. I've contacted both town council and hdb on this matter many times. for years, none of them have been able to solve this issue or identify where the water is seeping in from... my last resort now is to appeal to all out there to give me contacts of good experienced grouting experts who can help "catch" and seal up the water cracks in my walls. thank u u in advance
