Indoor walk off mats for commercial properties that set on top of the walking surface need to present a low profile to reduce trip and falls. Indoor walk off matting should also strive to control as much moisture as possible before it can be tracked onto hard floor surfaces. LEED recommendations are 10 lineal feet of walk off and this is a good baseline from which to start. Properly selected indoor floor mats designed for moisture control combined with a scraper mat or combination scraper/absorb floor matting will provide superior results. Ideally, office buildings should attempt to provide 18 lineal feet of walk off matting to trap up to 80% of sand, salt, grit and moisture before it can get tracked in further. Indoor floor mats play a crucial role in this system.
