A new patent-pending system called EdgeBan helps with leak-proof installation of self-leveling underlayment. EdgeBan creates a barrier around potential run-out areas, including wall gaps, toilet flanges, and floor vents. The maker says that its “Leveler Lock” design not only will seal run-out spots but will integrate with the underlayment, forming a strong bond and solid substrate to install flooring material over. Offered in strips, circles, and rectangles, each variation is easy to cut and simple to install, according to the manufacturer. Pricing for the parts ranges from $4 to $72. edgeban.com
