The vinyl flooring on my solid concrete kitchen floor in my four year-old house - laid by flooring contractors a few days before we moved in (winter time) - has, over time, stretched and produced ripples "like the Severn's tidal bore" at the edges on the longest axis of the one-piece sheet. The edges only were stuck down using a linen based double sided adhesive strip. This I have found to my cost, in a "previous life", is extremely difficult to get off!
The ripple is in the form of a single "wave" and runs practically the full width of the room: it starts about four inches from the edge and ends roughly where the adhesive strip begins, at which point it is flat. As this "wave" now runs across the main entrance to and from the kitchen it is posing a trip hazard.
How do I cure it please?
