Lifting seams and curling edges are the most visible failures and the most useful diagnostic. When the edge lifts, the base under it has usually failed first.
What failing artificial grass seams look like
- A visible join line across the yard that was not there on handover.
- A curled border standing up along the fence or the wall.
- Grass that slides or wrinkles when pushed.
- Corners lifting where a dog turns.
Why artificial grass seams and edges lift
Three causes dominate: a base that was not compacted or that settled, adhesive applied to a wet or dirty backing, and no proper edge restraint. In Orlando there is a fourth. The Atlantic hurricane season runs June 1 to November 30 (https://www.weather.gov/mlb/, HTTP 200), and a large exposed perimeter takes a wind load that works the edges before it works anything else, so perimeter pinning and edge fixing matter more here than in a landlocked market.
How the repair is scoped
A failed seam is lifted, the old adhesive removed, the base checked and re-levelled if it has moved, and the join re-made with jointing tape and outdoor polyurethane adhesive with the tufts trimmed back to clean backing. A lifting edge is re-pinned and the restraint checked. Both are minor works at a few hundred dollars when the base is sound. Where the base has settled, the repair becomes a section rebuild and lands in the several-thousand band.
What a correct perimeter has
- Edge restraint, fixed with adhesive, galvanised pins or rust-resistant screws.
- The base set below the top of the restraint, so the finished surface meets it level.
- Seam adhesive rated for outdoor use, on dry, clean backing.
- Wind detail appropriate to the exposure, which on an open lot with no windbreak is the first thing to ask about.
Preventing the second failure
Ask for the perimeter detail and the seam layout before the grass is cut, and check the edges after every storm. A single re-pin is cheap; a perimeter that fails progressively across a storm season is a re-lay.
Frequently asked questions
Can a lifting seam be glued again?
It can be re-seamed properly, which means lifting the join, cleaning the backing, checking the base and using jointing tape with outdoor polyurethane adhesive. Gluing a lifted edge down again without checking the base is the repair that fails twice.
Why does the edge curl here more than in a sheltered yard?
Wind. Inland Orlando is spared the storm surge but not the wind: an exposed perimeter takes the load of the hurricane season, and an edge that was never pinned moves with it. Perimeter anchoring is part of the specification, not an extra.
Is a visible seam a defect?
A well-made seam should be hard to see but rarely invisible. A seam that is standing up, opening or showing backing is a workmanship defect and belongs in the installer warranty conversation.
