Rubber mats are provided with most DumPits to keep rain out, but they may be purchased separately for any type of use. Most of our rubber mat material is 1/2” thick and comes in various widths (usually 6’, 7’, 9.5’ and 12’). Instead of two smaller mats, a larger single mat can be used to cover the entire grate area for two pits. Rope or chain handles can be added to make the mat easier to move. We carry bulk rubber material on hand and can customize the width and length to meet your specific needs. Contact us for more information!
