Some popular styles of doormats for outdoor use include rubber mats, textured mats and woven mats. Good mats are durable, absorbent and remove dirt well.
Doormats available in textured rubber are good for both gripping the floor and helping remove dirt. Many doormats also feature a rubber backing with a stiff carpet surface made from plastic fibers.
Textured mats can include these carpeted mats and raised texture mats with a rough polyester or other material surface that is embossed with a pattern. Grids and other geometric patterns are used to as they offer drainage channels for water when wiping shoes.
Woven mats are also available made from woven threads of plastics or an organic material like sea grass. These mats are lightweight, flexible, textured and offer plenty of drainage.
