Obvious lines where grass sections meet

Visible Seams and Joins in Artificial Grass

A good seam is genuinely hard to find. When joins stand out, the cause is nearly always something decided at install rather than something that developed later.

Some faults can be corrected in place; others need the sheet re-laying.

Pile direction

Synthetic grass has a nap. Two pieces laid with the pile running in opposite directions will always read as two different shades in certain light, however tight the join is.

This is the single most common cause of an obvious seam and it cannot be fixed without re-laying one piece.

Cutting and bonding

Seams should be cut between stitch rows so no backing shows, then bonded to jointing tape with adhesive across the full width. Adhesive dabs and stapled joins open up over time.

Excess backing left in the join creates a ridge that catches the light.

Blending after the join

Brushing infill across the seam lifts pile from both sides over the line and hides it. Skipping the infill leaves the join visible even when it is technically perfect.

Positioning seams away from primary sightlines — off the patio axis, for example — is basic good planning.

Frequently asked questions

Can an open seam be re-glued?

Yes, if the pile direction is correct and the edges are undamaged.

Why does the seam look lighter?

Almost always opposing pile direction reflecting light differently.

Do seams get worse over time?

Poorly bonded ones do, especially where they cross a traffic route.

Unhappy with a previous install?

We re-seam and re-lay artificial grass to a proper standard.
