Even basement walls that are waterproofed can wick water into the space through the footings. To combat this, the company has introduced Delta Footing Barrier, which is installed on top of footings before walls are poured. The 18-inch-wide product is made from layers of polyethylene fiber, polyester, and bonded polypropylene. Cost: 90 cents per linear foot. Cosella-Dörken. 888-433-5824. www.cosella-dorken.com.
