(Hotspot: Main Walk-off Mat)

Remember...“A set of barrier mats should be part of your strategy to keep dirt out of the building.”
Barrier (walk-off) mats, such as those shown here can be used effectively in all entryways, including front and side entrances, around the loading dock, receiving areas, freight entrances, and garage entrances into the building.
Mats differ in texture depending on the location (see cut out). A rough textured mat used outside the building entrance removes large particles. A medium textured mat is used just inside the building, and should be long enough so that everyone entering to take a minimum of five steps. Finally, a fine textured mat may be used as the final mechanism to remove small particles. As dirt accumulates, it migrates into the interior parts of the building. Therefore, all mats should receive frequent and thorough cleaning, particularly in heavily used areas.

(Hot Spot on course grained cutout)

A course textured mat is used outside building entrances to scrape large particles of dirt.

(Hot Spot on medium grained cutout)

A medium grained mat is used just inside the building entrance. The length should allow a person entering to take at least 5 steps on the mat.

(Hot Spot on fine grained mat)

A fine grained mat is used as the final means for removing small particles of dirt.
