    Basement Problems

    We have an older home and water was coming inside our foundation wall. We dug it out, cleaned the outside wall, rolled Deco Tac on the block We rolled the Deco Seal over it and it was a pretty easy process. Saved alot of money. There was no smell and got some of it on my hands but it washed off easy. Never did this before but you guys gave me confidence to do it myself. Kind Regards!!!!

    Repair Exterior Wall

    The products have been really nice to work with, I especially like the water cleanup. It looks great. I hope it is tough and durable against the soil back fill. We have mostly sandy soil so I haven't decided yet if I will put up foam board to help protect it. Thanks again for your help.
