Most artificial grass problems trace back to one thing: what happened before the grass was even unrolled. Ground preparation is invisible once the lawn is finished, which is exactly why understanding the process matters before work starts on your garden.

This guide walks through every stage of a proper UK artificial grass installation, so you know what to expect on the day and what separates a lawn that lasts fifteen years from one that ripples within twelve months.

Step 1: Site Survey

Before any digging starts, a proper installer surveys the garden in person. This covers soil type, existing drainage, slope, access for materials, and any surfaces that need removing first, such as old decking or overgrown borders. This stage decides how deep the sub-base needs to be and whether extra drainage work is required, which is why phone-only quotes are rarely accurate.

Step 2: Clearing the Existing Lawn

The current lawn, including roots, is fully dug out and removed. Skipping root removal is a common shortcut on rushed jobs, and it causes weeds to push through the new grass within a year or two. NeverMowUK clears to full depth as standard on every job.

Step 3: Excavation

The area is excavated to a depth of roughly 40 to 75mm below the finished level, depending on soil type and expected foot traffic. Heavier clay soils typically need a deeper excavation to allow for proper drainage material underneath.

Step 4: Sub-Base Installation

This is the layer that determines long-term stability. A sub-base of MOT Type 1 stone or granite grit is laid and compacted in stages using a plate compactor, not just tipped in and left loose. Each layer is compacted before the next is added, which prevents the ground from settling unevenly later.

Step 5: Weed Membrane

A permeable weed membrane is laid over the compacted sub-base. This stops weeds growing up from below while still allowing water to drain straight through, keeping the surface dry after rain.

Step 6: Sand Blinding Layer

A thin layer of sharp sand is spread and levelled over the membrane. This creates a smooth, even surface for the grass to sit on, ironing out any small inconsistencies left from the sub-base stage.

Step 7: Laying the Grass

The artificial grass is rolled out, left to settle, then cut and shaped to fit the garden precisely, including around patios, borders, and any fixed features. Pile direction is kept consistent across the whole area so the finished lawn has an even colour and texture from every angle.

Step 8: Jointing and Seams

For gardens larger than a single roll width, sections are joined using jointing tape and adhesive, then brushed along the pile direction to blend the seam invisibly. This step is where cheap installations most often show visible lines between rolls.

Step 9: Securing the Edges

The perimeter is fixed using galvanised nails, timber edging, or an existing hard landscaping feature like a patio or composite decking edge, keeping the grass taut and preventing it lifting at the borders over time.

Step 10: Infill and Final Brush

A sand or rubber infill is worked into the pile in some products to help the fibres stand upright and add weight that keeps the grass stable. A final brush across the whole lawn lifts the pile for a natural, even finish.

Step 11: Final Inspection

The finished lawn is checked for level, seam quality, edge security, and drainage before handover, alongside a walkthrough of basic care so the lawn is looked after correctly from day one.

How Long Does the Process Take?

A standard residential garden (30 to 40m2) typically takes one to two days from clearance to finished lawn. Larger or more complex gardens, particularly those needing extra drainage work or multiple joins, can take longer. This mirrors the process and timeframe for our patio installations, which follow a similar ground-preparation-first approach.

What You Should See on Installation Day

• Old lawn and roots fully removed before any new material arrives
• A compacted sub-base you can walk on without it shifting underfoot
• Careful trimming around edges, patios, and existing features
• Seams that are barely visible once brushed
• A final walk-through explaining basic brushing and care

If any of these steps are skipped or rushed, it is worth asking why before the job is signed off.

Caring for Your Lawn After Installation

Once installed, artificial grass needs very little upkeep: an occasional brush to keep the pile upright, a rinse to clear debris, and removal of leaves or moss in shaded corners.

Frequently Asked Questions

Can artificial grass be installed in winter? Yes, installation can happen year-round in the UK, though very wet or frozen ground can extend timelines slightly as the sub-base needs proper compaction to be effective.

Do I need to be home during installation? Not for the full process, but being available at the start for the site walkthrough and at the end for final inspection is recommended.

How disruptive is the installation process? Most jobs involve a skip or van on the driveway and some noise from compaction equipment during the day, with minimal disruption otherwise.

What happens to the old grass and soil that’s dug out? This is cleared and removed by the installer as part of the job, so you are not left with waste to dispose of yourself.

Can artificial grass be laid over an existing patio or concrete? Not directly. A patio or concrete base needs a compatible sub-layer added on top to allow proper drainage and cushioning before grass can be laid.
