70 - 80% of all dirt, dust and grime in public buildings is tracked in from outside and spread through the floors of the buildings.
The cost of removing 1kg of dirt from a modern building in the USA is in excess of $1,300. Of that only 5-10% is spent on supplies and equipment, the rest is labour.
It takes only 1,500 people entering a building where there is no mat to remove 42% of the floor finish. Carpet is similarly effected in terms of wear and unsightly appearance.
One good 1.8 x 1.2m mat will save 2-4 times its cost in labour in just one month. If a mat costs $120-$150 and collects .5kg of dirt it will save $600-$700 in labour.
