Automatic Pool Covers for Infinity and Vanishing-Edge Pools
An infinity or vanishing-edge pool removes the wall a track wants to follow. The leading edge needs two guides and a far-end stop. A knife-edge or a raised vanishing wall is not a stop. This page is the raised-wall brief. Many of these pools should not take an automatic fabric cover, and that is a valid outcome.
What the edge took away
A standard rectangular pool has coping on four sides. A vanishing edge has a weir. Water goes over. There is no deck to fasten a far-end stop, and often no place for a glider. Hiding a track on the weir fights the hydraulic design of the edge. That is not a detailing preference. It is a different product job.
When a review can continue
Some pools vanish on one short end and still have two long track walls and a housing on the solid end. That can work if the weir is not asked to be a rail. A pool that vanishes on a long side usually fails. Raised perimeter walls without a walkable coping fail for the same reason: no honest guide path.
| Edge condition | Automatic prospect | Stop if |
|---|---|---|
| Weir on the short far end, two solid longs | Possible with a custom stop plan | The weir is the only far-end structure |
| Weir on a long side | Usually no | Anyone promises a hidden rail on the weir |
| Raised wall, no coping walk | Usually no | Fasteners would sit in the vanishing trough |
| Catch basin owns the housing end | Find another end | The box would sit in the surge tank |
What to specify instead
If automatic fails the review, a tested manual safety cover or a seasonal winter cover may still be the honest barrier. Do not stretch fabric across a weir and call it a safety cover. The installed configuration would not match a standard track test.
When the honest answer is no
A raised vanishing wall that the bar cannot cross is a valid no. Write that down. Then specify a safety cover that can follow the outline, or a custom engineering review that the manufacturer actually signs.
A custom pool page is the next stop only if the rest of the architecture is also nonstandard. The weir itself is this page.
The weir is the veto, not the view
A raised vanishing wall that the bar cannot cross is a valid no. The vanishing wall, the trough, and the quiet end often want three different things. A cover needs one housing and two rails. If those cannot land without crossing the weir, write no and move to a safety cover that can follow the outline.
常见问题
- Can we put top track on the vanishing edge?
- Almost never. The weir is wet, narrow, and not a walking deck. Ask for a written no rather than a clever bracket.
- Does a perimeter-overflow pool have the same problem?
- Yes, often worse. The overflow trough claims the edge a track wanted. Treat it as custom, not as a catalog rectangle.
- Can tracks sit on the catch-basin wall?
- Only with a structural and waterproofing detail that the cover maker accepts. A thin weir is not a default track wall.
- Can I cover only the swimming basin and leave the trough open?
- Only if the leftover water is still an acceptable barrier and the manufacturer will sign that split. A pretty render is not that signature.
