When people picture an artificial grass installation, they’re usually picturing the turf itself, the color, the blade length, how soft it looks. What they don’t picture is the seam, but it’s one of the biggest factors in whether a lawn looks real or not.

What Is a Seam, Exactly
A seam is where two pieces of turf meet and get joined together. Almost every yard needs more than one roll of turf to cover it, so seams are unavoidable on most installs. The problem is, a bad seam is one of the easiest things to spot. If the line between two pieces is visible, or the grass doesn’t match up right at the edge, that’s usually the first thing your eye catches, even before you notice anything else about the lawn.

Why the Seam Makes or Breaks the Look
A good seam is basically invisible. The grain of the turf lines up, the blades blend into each other, and there’s no gap or ridge where the two pieces meet. A bad one draws a straight line right across your yard and makes the whole thing look like two separate mats instead of one lawn. So the quality of the seam ends up mattering just as much as the quality of the turf itself.

How the Seam Gets Cut Matters Too
Cutting the edge matters just as much as joining it. A rushed, straight cut through the turf backing tends to leave a visible line no matter how well it’s glued afterward. We take the time to cut each edge carefully so the seam sits between the blades instead of cutting across them, which is what actually keeps the line from showing once the pieces are joined.

Artificial Grass Glue vs Tape
Once the pieces are cut and lined up, they need to be joined, and this is where glue and tape come in. Tape is the faster option, but it locks the seam in place the moment the turf gets pressed down. There’s no room to nudge it or fine-tune the alignment afterward, so any small misalignment during install just stays there, and it doesn’t create a true bond between the turf backing and the ground underneath either. That makes it more likely to lift or shift over time, especially with temperature changes or heavy foot traffic. On a hot day, that gap can widen just enough to show, and once it does, it doesn’t close back up on its own.
Glue takes longer to apply, but installers get a window to adjust and reposition the turf before it fully sets, so the seam can be fine-tuned into place instead of committed to on the first press. Once it cures, it forms an actual bond, and the seam becomes a solid, permanent joint rather than something held together by adhesive backing. That’s the version that holds up through BC winters, foot traffic, and years of sun exposure without the seam starting to peek through.
We use artificial grass glue instead of tape on every install for these reasons. A properly glued seam, especially one that’s already cut with an S-cut instead of a straight line, is about as close to invisible as a seam gets. It’s a small detail in the middle of a much bigger installation, but it’s one that shows.
