An opening seam, lifted edge, wrinkle, low spot, missing infill, stain, burn, tear, or worn path describes what can be seen. It does not identify the cause by itself. Traffic, poor attachment, material damage, base movement, roots, erosion, standing water, or an outside repair can produce similar symptoms and require different corrections.
A useful repair assessment records the location, size, age of the installation if known, recent changes, water behavior, nearby hardscape, and whether the concern is spreading. Wide and close photographs can narrow the first questions, but lifting or opening the affected area may be necessary to understand the seam, backing, restraint, or base.
