In hospitals many times the flooring will be welded in the OR's and sterile areas and just butted in the non-sterile areas.
There are chemical welds and heat welds. Welds do hold the seam together. And yes keep the seam from filling with dirt, keepoing them sterile but not just for that purpose. Look up the definition of weld.
Perhaps Ray will chime in. He is the resilient guru.
