INTRODUCTION TO SEAM ARTIFICIAL TURF SEAMING

[/vc_column_text][/vc_column][vc_column width=”1/2″][vc_column_text css=”.vc_custom_1697030400516{padding-top: 19px !important;}”]When installing artificial turf, creating seamless joins between sections of grass is crucial for both aesthetics and durability.

These joins, known as seams, come in two main types:[/vc_column_text][vc_column_text css=”.vc_custom_1697030400517{}”]HEAD SEAMS[/vc_column_text][vc_column_text css=”.vc_custom_1697030400518{}”](Grain-Perpendicular Seams)

Head seams occur where two ends of turf rolls meet, running perpendicular to the stitch rows.

These seams are structurally sound but visually sensitive and should be used sparingly and only when necessary (e.g., managing offcuts or transitioning in tight spaces).[/vc_column_text][/vc_column][vc_column width=”1/2″][vc_single_image image=”23840″ img_size=”full” alignment=”center” css=”.vc_custom_1697030400519{padding-bottom: 50px !important;background-image: url(http://pgblocal.test/wp-content/uploads/seaming-images-for-exports.png) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: contain !important;}”][/vc_column][/vc_row][vc_row top_padding=”60″][vc_column][vc_column_text css=”.vc_custom_1697030400520{margin-bottom: 50px !important;padding-top: 50px !important;}”]SIDE SEAMS[/vc_column_text][vc_column_text css=”.vc_custom_1697030400521{}”]Side seams are the standard method for joining two rolls of turf laid out side-by-side, running parallel to the stitch rows (grain) of the turf.

These seams typically stretch across the longer axis of the installation area.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section][vc_row top_padding=”100″][vc_column][vc_column_text css=”.vc_custom_1697030400523{}”]

ALIGN THE TURF EDGES

[/vc_column_text][vc_column_text css=”.vc_custom_1697030400527{margin-top: -20px !important;}”]

  • Lay the turf sections side by side, ensuring the blades lean in the same direction for a seamless appearance.
  • To marry the seam, trim the edges at least three stitch rows to create clean, straight lines for better bonding.

POSITION SEAM TAPE

[/vc_column_text][vc_column_text css=”.vc_custom_1697030400534{margin-top: -20px !important;}”]

  • Place seam tape centered underneath where the turf edges meet.
  • Ensure the adhesive side faces up and runs the entire seam length. Use spikes if needed to secure the seaming tape in place temporarily. Before moving on, ensure the turf has not moved, and the seam is still optimal.

  • Carefully peel off the protective backing to expose the adhesive surface.
  • Work in small sections to prevent premature sticking.
  • Keep the turf slightly lifted while peeling to avoid debris or dust sticking to the adhesive.

JOIN THE TURF SECTIONS

[/vc_column_text][vc_column_text css=”.vc_custom_1697030400546{}”]

  • Carefully align the turf edges and press them firmly onto the adhesive. For best results, use 2-4 people and maintain an even gap throughout the process. Smooth the seam by hand to eliminate gaps.
  • Follow the standard seaming process using the zipper method for a tight and secure seam.

  • Place nails every 6 inches and 2 inches from the seam along the seam to provide additional reinforcement.
  • Drive nails in at a slight angle to anchor the turf securely without pulling the fibres down.

WEIGH DOWN THE SEAM

[/vc_column_text][vc_column_text css=”.vc_custom_1697030400558{}”]

  • Place weight along the seam to ensure a secure bond. The best method is to use 2×6 planks weighed down with sandbags for at least 24 hours.
  • Remove or hammer down the temporary nails holding the turf in place.

Work in Warm Weather

[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_row_inner][vc_column_inner css=”.vc_custom_1765246496450{background-color: #005537 !important;}”][vc_column_text]

Turf is more pliable in warmer conditions, making seams easier to align and secure.

[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][vc_column width=”1/3″][vc_row_inner][vc_column_inner][vc_column_text]

Use a Chalk Line

[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_column_text]

Mark a straight line where the turf edges will meet for precise alignment.

[/vc_column_text][/vc_column][vc_column width=”1/3″][vc_row_inner][vc_column_inner][vc_column_text]

Minimize Head Seams

[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_column_text]

Avoid head seams (end-to-end joins) whenever possible, as they are harder to conceal. Side seams (lengthwise joins) are easier to blend.

[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=”.vc_custom_1697030400563{padding-bottom: 100px !important;}”][vc_row][vc_column width=”1/2″][vc_column_text css=”.vc_custom_1697030400564{padding-top: 22px !important;}”]Inspect Blade Direction:

  • Check the Pile Direction: Ensure all turf sections have blades leaning in the same direction to avoid visible seams.
  • Use Weight for Drying: Place weights (e.g., sandbags) along the seam while the adhesive cures for a stronger bond.
  • Leave a Gap for Expansion: Leave a small gap between turf sections to allow for expansion and contraction in extreme temperatures.
  • Always Use a Sharp Utility Knife: This ensures clean cuts without fraying the backing.
  • Take Your Time to Make Precise Cuts: Rushing can result in uneven seams.
  • Inspect the Blades After Marrying the Seams: Ensure they are upright and uniformly aligned.

What Not To Do

[/vc_column_text][/vc_column][/vc_row][vc_row bg_color=”#00000000″ top_padding=”25″ bottom_padding=”20″][vc_column bg_color=”#0B3D2C” column_padding=”padding-2″][vc_column_text]

Don’t Rush the Adhesive Application

Ensure the adhesive on the pre-applied seam tape is evenly pressed along the edges.

[/vc_column_text][/vc_column][/vc_row][vc_row bottom_padding=”20″][vc_column bg_color=”#0B3D2C” column_padding=”padding-2″][vc_column_text]

Avoid Visible Gaps

Misaligned edges or uneven trimming create noticeable gaps in the seam.

[/vc_column_text][/vc_column][/vc_row][vc_row bottom_padding=”20″][vc_column bg_color=”#0B3D2C” column_padding=”padding-2″][vc_column_text]

Don’t Skip the Seam Roller

Ensure the adhesive on the pre-applied seam tape is evenly pressed along the edges.

[/vc_column_text][/vc_column][/vc_row][vc_row bottom_padding=”20″][vc_column bg_color=”#0B3D2C” column_padding=”padding-2″][vc_column_text]

Don’t Overstretch the Turf

Pulling the turf too tightly can cause seams to separate over time.

[/vc_column_text][/vc_column][/vc_row][vc_row bottom_padding=”20″][vc_column bg_color=”#0B3D2C” column_padding=”padding-2″][vc_column_text]

Avoid Heavy Traffic on Fresh Seams

Allow adhesive to cure fully before walking or placing weight on the seams.

[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=”.vc_custom_1697030400573{padding-top: 80PX !important;padding-bottom: 80PX !important;}”][vc_row][vc_column column_padding=”padding-3″][vc_custom_heading text=”Key Guidelines for a Flawless Finish” font_container=”tag:h1|font_size:45px|text_align:center” css=”.vc_custom_1765244389518{padding-bottom: 30px !important;}” alignment=”center”][vc_column_text]

The most crucial step is to follow our seaming guidelines carefully—these simple techniques can make the difference between a seamless look and a visible flaw. The diagrams below illustrate the most common seaming mistakes. By following our recommended approach, you’ll achieve clean, nearly invisible seams once your installation is complete. Note that the outer three rows of turf blades on each edge tend to lean outward.

[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text css=”.vc_custom_1697030400574{margin-top: 20px !important;margin-bottom: 50px !important;}”]TO ENSURE THE BEST RESULTS:

  • Trim off the outer three turf blade rows before beginning your seam.
  • Leave a 3/8″ gap between the pieces. Too little space can create a noticeable “mohawk” effect along the seam, while too much space can result in a visible “valley.”
