Introduction

The type of contact “to cover or overlay” is by far the most commoon in J5, representing about 53% of the total.

Typically covers and overlays appear in open areas where layers of natural seasonal accumulation build one atop the other. Another common occurrence is the buildup of a succession of floor surfaces with continued use.
