Standartparks Entrance Mat System is a one of a kind design that allows an installation into your entry way with a bottom basin that will drain out your excess water / mud from your porch / entrance area. There is a growing trend of porch and entry way problems - our system will completely remove that. With included bottom basin, our entrance mat systems have a unique design with a rubber or textile top - which easily rests into the basin - you attach your outlet pipe to the basin, and can be cleaned and removed at any time - while maintaining a secure structure. By doing this, no more water , debris, or mud will be on your front porch or entry way. All packages include the rubber or textile top (defendant on your selection) as well as the underlying basin.
