Artificial grass can be a practical way to transform a patchy, muddy, difficult-to-maintain lawn into a cleaner, more consistent outdoor space.
This YARDORA installation guide walks you through the complete process of replacing an existing natural lawn with artificial grass—from removing the old grass and preparing the base to cutting, seaming, securing, and finishing the turf.
This guide is intended primarily for residential artificial grass installation over soil or an existing lawn area.

A good artificial grass installation starts before the old lawn is removed.
Take time to plan the turf direction, seams, final height, drainage, edging, and required materials.
Measure the longest length and widest width of the installation area.
For irregular yards, divide the space into smaller rectangles, calculate each section separately, and add the areas together.
Allow additional turf for trimming, curves, and seam alignment. For relatively simple residential projects, approximately 5–10% extra material is commonly allowed. More complex shapes may require additional material.
Plan all turf pieces so the grass blades face the same direction.
Artificial grass viewed from opposite pile directions can appear lighter or darker even when it is the exact same product.
Use as few seams as practical and, where possible, position seams away from the most visible areas.
Before excavation, identify:
sprinkler heads, irrigation lines, drains, electrical lines, underground utilities, tree roots, edging, and any areas where water currently collects.
If underground utilities may be present in the United States, contact 811 before digging.
The finished surface should allow water to drain away from buildings.
Where site conditions permit, a gentle slope of approximately 1–2%, or roughly 1/8–1/4 inch per foot, is commonly used for drainage.
If the existing yard already develops standing water or severe drainage problems, correct the underlying drainage issue before installing artificial grass.
Important: Artificial grass should not be expected to correct an existing drainage problem by itself.
Depending on the size and condition of your project, commonly used installation materials include:
Do not install artificial grass directly over living natural grass.
Remove the existing natural grass, weeds, roots, and loose organic material. For larger lawns, a sod cutter can make this process considerably easier.
Many residential artificial grass projects excavate approximately 3–4 inches (75–100 mm) from the existing grade. However, the correct excavation depth depends on the existing soil, drainage conditions, base thickness, edging, and desired finished turf height.
Remove soft soil, decomposing roots, and unstable organic material. Avoid leaving a thick layer of loose topsoil directly underneath the turf base.
If existing sprinkler heads will no longer be used, they should be properly capped, removed, or relocated.
Installation Tip:
Plan the finished turf elevation so it sits appropriately next to patios, sidewalks, edging, doors, drains, and other surrounding surfaces.
A stable perimeter helps hold the base material in place and provides a clean edge for the finished artificial grass.
If the installation area does not already have a secure perimeter, install an appropriate edge restraint before completing final base preparation.
Depending on the project, perimeter options can include:
concrete curbing, treated or composite edging, paver edging, or another secure landscape border suitable for artificial turf installation.
The perimeter should be stable enough to prevent base material from migrating and to support the chosen fastening method.
Installation Tip:
Establish curves and irregular borders before laying the turf. This makes the final trimming process considerably easier.
The base is one of the most important parts of a successful artificial grass installation.
Spread a suitable compactable aggregate over the prepared area and grade it according to the planned drainage direction.
Crushed aggregate, decomposed granite, or another compactable turf base appropriate for local soil conditions may be used.
Compact the material in thin layers, rather than attempting to compact one thick loose layer at once.
A total compacted base of approximately 2–4 inches (50–100 mm) is common for many residential projects. Softer soil, clay-heavy soil, high-traffic areas, or difficult drainage conditions may require a deeper or differently engineered base.
For larger installations, a plate compactor generally produces a firmer and more uniform surface.
The finished base should feel solid underfoot without loose areas, pumping, ruts, or significant movement.
Installation Tip:
Drainage performance is largely determined by the site grading and base system—not just by the drainage holes in the artificial grass.
After the base has been compacted, rake the surface smooth.
Remove large stones, ridges, depressions, and irregularities that could eventually become visible through the artificial grass.
Use a long level, straightedge, or string line to verify the grade.
Fill low spots, compact them again, and make the final surface as smooth and uniform as practical.
A suitable geotextile or weed barrier may be incorporated into certain installations depending on site conditions.
For pet areas, avoid placing a non-draining waterproof layer immediately underneath the turf where urine or moisture could become trapped.
Installation Tip:
Walk over the entire prepared base before laying the turf. If you can clearly feel a bump or depression now, it may remain visible after installation.
Carry the turf into position whenever possible rather than dragging the grass face across rough ground.
Roll the artificial grass out over the prepared base with the fibers facing the planned direction.
If conditions permit, allow rolled turf some time to relax and warm before completing the final cuts. This can help reduce temporary curling and wrinkles caused by storage or transportation.
Leave extra material around the edges until the final position has been confirmed.
If the project requires multiple turf pieces, check again that the pile direction of every piece is the same.
Installation Tip:
Always match the direction of the grass blades before judging whether two turf sections match visually.
Once the turf is correctly positioned, begin trimming it to the shape of the installation area.
Most major cuts are easier from the backing side using a sharp heavy-duty utility knife.
Follow the backing rows when making long straight cuts.
When trimming around curves, walls, patios, landscape borders, or other irregular objects, make several smaller relief cuts rather than attempting one large cut.
Do not cut the turf exactly to final size until you are confident the entire piece is correctly positioned.
Change knife blades frequently. Artificial turf backing can dull blades relatively quickly.
Safety Tip:
Use a stable cutting surface, keep your hands clear of the cutting path, and never cut toward your body.
Larger installations may require two or more pieces of artificial grass.
Position the sections so the backing edges meet cleanly without overlapping.
Both pieces must have their grass fibers running in the same direction.
Trim damaged factory edges or unnecessary backing material where required. Some installers remove one or two outer tuft rows to create a cleaner seam.
Position artificial turf seam tape underneath the joint and center it between the two pieces.
Apply a turf-compatible adhesive according to the adhesive manufacturer's instructions.
Carefully place both turf edges onto the seam tape.
The backing edges should meet closely without overlapping or buckling, and grass fibers should not become trapped underneath the seam.
Weight or secure the seam as recommended while the adhesive cures.
Installation Tip:
Before applying adhesive, step back and inspect the seam from several viewing angles. A dry seam is much easier to adjust than one that has already been glued.
After the turf is correctly positioned and all seams are complete, secure the outer edges.
For many soil and aggregate-base installations, turf nails or landscape spikes are used around exposed perimeters.
Approximately 4–6 inches (100–150 mm) between perimeter fasteners is common for many installations, with closer spacing potentially used around curves, transitions, and other stress points.
Exact fastening requirements depend on the turf, site, edging system, local conditions, and installation method.
Separate the artificial grass fibers before installing each fastener.
Drive the fastener so it holds the backing securely without crushing the turf or creating a visible depression.
Afterward, brush the fibers back over the fastener head.
Some artificial grass installations use infill to provide additional ballast, support grass fibers, and improve the finished appearance.
Whether infill is required—and how much should be used—depends on the specific turf product and application.
Use only clean, dry, turf-compatible infill.
For pet areas, select an infill specifically suitable for pet use and appropriate drainage.
Apply infill gradually in light, even passes instead of dumping large amounts into one location.
Brush the turf between applications so the material settles down between the fibers rather than remaining on the surface.
Installation Tip:
More infill is not automatically better. Excessive infill may change the appearance, feel, drainage characteristics, and surface temperature of the turf.
Artificial grass fibers can become compressed while the turf is rolled, stored, and transported.
After installation, use an artificial turf rake, stiff synthetic-bristle brush, or suitable power broom to lift the grass fibers.
Rake or brush generally against the natural direction in which the pile is leaning. This helps the blades stand more upright.
Pay particular attention to seams and perimeter fasteners so surrounding fibers help conceal the installation hardware.
Remove loose backing scraps, cut fibers, adhesive residue, and construction debris.
The appearance of the turf often continues improving after it has had time to warm, relax, and be groomed.
Before placing heavy furniture on the turf or opening the area to regular traffic, inspect the complete installation.
Confirm that water can travel toward the intended drainage area and is not being directed or trapped against the house.
Inspect seams, edges, transitions, and fasteners.
Make sure nothing is lifting and that there are no exposed sharp points.
Allow seam adhesive to cure for the full period specified by the adhesive manufacturer before heavy traffic or washing around the seam.
Confirm that:
gates open correctly, doors remain unobstructed, drains are accessible, irrigation valves remain usable, and any necessary utility access has not been covered.
Installation Tip:
Inspect the area again after the first substantial rain. Persistent puddling often indicates an underlying grading, base, or drainage issue that should be corrected.
Artificial grass can also be used in yards where dogs regularly play or relieve themselves, but drainage and cleaning become especially important.
Pick up solid waste promptly and rinse the affected areas when needed.
Use cleaning products specifically labeled as safe for synthetic turf.
For frequently used pet areas, periodic deep rinsing and a compatible artificial-turf enzyme cleaner may help manage odor.
Avoid installing an impermeable layer immediately underneath pet turf unless the overall system includes a properly designed drainage solution.

INSTALLATION GUIDE
Measure the installation area carefully and sketch the layout before ordering materials.
Remove the existing surface to the planned excavation depth.
Install and compact the recommended aggregate base in even lifts.
Set edging firmly around the perimeter and check the finished height.
Unroll the turf with the grain facing consistently and let wrinkles settle.
Trim from the underside with a sharp blade, taking small passes for accuracy.
Align adjoining pieces, apply seam materials, and secure the turf with appropriate fasteners.
Apply the recommended infill in passes, then brush against the grain to lift the blades.
Check seams, edges, drainage, and fiber direction before opening the area for use.
No. Existing natural grass, roots, weeds, and unstable organic material should be removed first. Installing artificial grass directly over living grass can create an unstable surface and contribute to drainage and settlement problems.
Many residential projects excavate approximately 3–4 inches, but there is no single correct depth for every yard. Soil conditions, drainage, base thickness, surrounding hardscape, edging, and final turf elevation all affect the required depth.
Artificial grass installed over soil normally requires a stable, compacted base. Crushed aggregate, decomposed granite, or another locally appropriate compactable turf base may be used depending on site conditions.
A compacted base of approximately 2–4 inches is common for many residential installations. Difficult soil, drainage issues, heavy traffic, or other site conditions may require a different base design.
It depends on the site and installation system. A suitable geotextile may be useful in some applications. For pet installations, avoid using a waterproof barrier directly beneath the turf if it can trap urine or moisture.
Yes. Water still needs an appropriate route away from the installation area.
The site grade, compacted base, surrounding hardscape, and turf drainage system all work together. Artificial grass alone will not correct an existing drainage problem.
When multiple pieces are used, all pieces should normally have their grass fibers running in the same direction.
Different pile directions can make identical pieces appear to be different colors.
Prepare clean backing edges, align the pile direction, use suitable turf seam tape and compatible adhesive, prevent fibers from being trapped underneath the joint, and brush the finished seam after curing.
Correct positioning before adhesive is applied is particularly important.
No. Infill requirements depend on the turf product and intended application.
If infill is used, follow the recommendations appropriate for that turf and use only compatible materials.
Smaller, relatively simple areas can often be suitable for experienced DIY homeowners.
A professional installer should be considered when the site has significant drainage problems, steep slopes, retaining walls, extensive seams, complicated cutting, soil movement, large areas, or uncertain underground utilities.
For relatively simple residential layouts, approximately 5–10% additional material is commonly allowed for trimming and fitting.
Irregular shapes, multiple seams, complex curves, and layouts that require careful pile alignment may require more.
