AdmiralTM SpaceMakerTM Outdoor Flooring has a Super Seal technology to help prevent water from collecting by your foundation wall. This will help lengthen the life of your foundation and help remove moisture from your home. By sealing together and directing water to the outside edges of the floor, the space under your outdoor floor is dry, can be enclosed with an access door for secure storage and will not have weeds, bugs, or animals living there.
