 GERMANY KOSTER 21 really works well after trying so many brands and contractor, what further amazing me is the cooling effect in my master bedroom. So nowadays the aircon take shorter time to cool the room.

Been trying on one famous waterproofing brand on my basement wall but had failed after 3 months. Few patches of water dampness are visible on certain areas. Water leak out during hacking for repairing. Waterproofing solution needs to redo on the whole area. After using KOSTER PRODUCTS (i.e. TG 500 and NB1 Grey, the leakage stops and no more dampness. Highly recommended KOSTER to everyone.
