Seaming, infill and drainage mistakes that cost callbacks

A seam that stays invisible

The sequence that avoids the most common seam callback: a visible line or a lifting edge.

1. 1. Match pile direction. Lay both pieces with the fibre running the same way before any cutting. A reversed piece shows from every angle.
2. 2. Trim the factory edge. Remove the selvage edge on both pieces and cut between stitch rows so no fibre is cut through.
3. 3. Set the gap. Keep the gap consistent along the full length so the stitch rows keep their spacing across the seam.
4. 4. Tape and adhesive. Centre the seam tape, apply adhesive per the product guidance, and keep fibre out of the adhesive as each side is laid down.
5. 5. Weight and cure. Press the seam down and let it cure before infill or brushing. Loading a green seam is how edges lift later.

Seaming mistakes

• Mixed pile direction. The single most visible error on a finished lawn. Check it on every piece before the knife comes out.
• Seams against the main view. Run seams toward the primary viewpoint where the layout allows, so light doesn't cross them.
• Cutting fibre at the seam. Cut from the back between stitch rows. Cut tufts leave a bald line that no brushing hides.
• Rushing the cure. Infilling or power-brushing before the adhesive has set pulls the seam open.

Infill mistakes

• Dumping instead of spreading. Apply infill in several light passes with a spreader, brushing between passes, rather than one heavy load.
• Infilling wet turf. Infill clumps on wet fibre and sits on top instead of working down to the backing.
• Guessing the quantity. Use the infill guidance for the specific product. Too little lets the fibre lay over; too much buries it.
• Skipping the final brush. The last brush against the grain stands the fibre up and settles the infill evenly.

Infill is part of the surface, not an afterthought. Budget crew time for it like you budget time for seams.

Drainage and base mistakes

Turf passes water through its backing; what happens next is decided by the base. A base that holds water under the turf causes most of the problems that get blamed on the material.

• No fall. A dead-flat base on a heavy soil leaves water nowhere to go. Grade the base so water leaves the area.
• Under-compaction. A base that settles unevenly after the first rains shows every low spot through the turf.
• Ignoring existing drainage. Downspouts, irrigation lines and neighbouring runoff don't disappear because the lawn changed. Route them before the base goes down.
• Edges that dam water. Borders set above the base can trap water at the perimeter. Check the edge detail against the fall.

Common questions

What causes a visible seam on artificial turf?

Most often mixed pile direction, fibre cut at the seam, or an inconsistent gap between the two pieces. All three are decided before the adhesive goes down.

Why does infill clump or sit on top of the turf?

Usually because it was applied to wet fibre or in one heavy load. Apply it dry, in light passes, brushing between each.

Is poor drainage a turf problem or a base problem?

Almost always the base. The turf passes water through; the graded, compacted base underneath has to carry it away.

Does Superior Turf Direct install or train crews?

No. Superior supplies materials only and never installs. Follow the installation guidance for the product and your own trade practice.
