First line of defense
Effective entrance systems capture soil and moisture before it spreads onto adjacent flooring.
Length and traffic
The appropriate system depends on entrance geometry, climate, pedestrian volume and wheeled traffic.
Maintenance
A dirty entrance mat cannot continue capturing soil effectively; cleaning is part of the system.
Transition
Edges and changes in level should be planned with accessibility and trip-risk requirements in mind.
Commercial flooring decisions depend on the actual substrate, moisture conditions, traffic, cleaning regime, accessibility requirements, fire/building rules, manufacturer instructions and local code. This site is for planning and comparison, not installation instructions.
