Turf and shingle laying

For UK homeowners, investing in professional landscaping ensures that your new lawn doesn't become a bog in winter and your shingle areas don't disappear into the mud. Whether you are refreshing a small terrace garden or overhaulng a large suburban plot, understanding the process and costs involved will help you achieve a high-end finish that adds genuine value to your property.

What Does the Work Involve?

• Site Assessment: Measuring the area, checking soil pH, and identifying drainage "low spots" or underground utilities.
• Excavation: Stripping away old grass, weeds, and debris, then digging down to the required depth (usually 50-100mm).
• Ground Preparation: Rotovating the soil and adding high-quality screened topsoil or sharp sand to create a level, nutrient-rich base.
• Drainage Management: Grading the site to ensure water flows away from the house and doesn't pool on the new lawn.
• Membrane Installation: Laying a heavy-duty, non-woven geotextile weed membrane beneath shingle areas to prevent weed growth and sinking.
• Laying Turf: Installing rolls in a "brickwork" pattern, ensuring tight joints without overlapping, followed by firming down to remove air pockets.
• Shingle Spreading: Distributing the chosen aggregate (e.g., Cotswold buff, pea shingle, or slate) to a consistent depth, typically 40-50mm.
• Edging: Installing timber, brick, or metal edging to keep the shingle and turf permanently separated.

Typical Costs

Prices for turf and shingle projects vary based on the quality of the turf selected and the ease of access to your garden. If materials have to be carried through a house or via a narrow side gate, labour costs will increase significantly.

Note: Prices include VAT at 20%. The "High" end of the scale typically accounts for gardens with poor access, significant levelling requirements, or high-end decorative aggregates like Scottish Pebbles or Blue Slate.

How Long Does It Take?

• Small Gardens (up to 30m²): 1 day. This usually covers prep in the morning and laying in the afternoon.
• Medium Gardens (30m² - 80m²): 2–3 days. Requires more significant excavation and soil moving.
• Large Projects (100m²+): 4+ days. Often involves machinery like mini-diggers and multiple deliveries of bulk bags.
• Weather Impact: Heavy rain can delay turfing as the soil becomes unworkable; very hot weather requires immediate, intensive watering schedules.

DIY or Professional?

Laying shingle is a manageable DIY task for those with a strong back, provided the weed membrane is installed correctly. However, turfing is much more deceptively difficult. Turf is a living product that begins to degrade within 24 hours of being cut; if your preparation isn't finished when the pallets arrive, the lawn is likely to fail.

Professional landscapers use heavy-duty rotovators and specialized leveling tools to ensure the lawn is perfectly flat. A DIY lawn often ends up "lumpy," which makes mowing difficult and leads to scalping.

Choosing the Right Tradesperson

• Check Credentials: Look for members of the British Association of Landscape Industries (BALI) or the Association of Professional Landscapers (APL).
• Waste Management: Ensure they hold a valid Environment Agency Waste Carrier Licence to dispose of your old garden waste legally.
• Verify Portfolio: Ask for photos of lawns they laid 12 months ago, not just on the day of completion, to see how they have bedded in.
• Questions to Ask:
  • Is the topsoil "screened" to remove stones and glass?
  • What grade of weed membrane do you use for the shingle areas?
  • How do you handle drainage if the garden slopes toward the house?
  • Do you offer a "guaranteed take" on the turf if I follow your watering instructions?

UK Regulations

• Sustainable Drainage Systems (SuDS): Shingle is a permeable surface, which usually means you don't need planning permission, even in front gardens.
• Waste Disposal: Under the "Duty of Care" regulations, you are responsible for ensuring your contractor disposes of soil and turf at a licensed facility.
• Water Usage: Check for local hosepipe bans. Most water companies allow a grace period for watering in new turf, but you may need to notify them.

Common Problems

• Turf Gapping: If turf is not "butted" tightly together or is allowed to dry out, the rolls shrink, leaving ugly brown gaps.
• Weed Infestation: Using a cheap, thin membrane under shingle allows perennial weeds to push through from below.
• Poor Levelling: Failure to properly compact the soil before laying turf leads to "settling," creating dips that collect water.
• Sub-base Mixing: Without proper edging, shingle will inevitably migrate into your lawn, potentially damaging your lawnmower.

Frequently Asked Questions

When is the best time of year to lay new turf?

Spring (March to May) and Autumn (September to November) are ideal. The weather is generally moist and mild, which helps the roots establish quickly without the stress of extreme heat or frost.

How long should I wait before walking on my new lawn?

You should avoid walking on new turf for at least 2 to 3 weeks. Wait until the roots have firmly knitted into the soil; you can check this by gently trying to lift a corner of a roll.

Can I lay new turf over my existing grass?

No. The old grass will rot, creating a barrier that prevents new roots from reaching the soil. It also causes uneven settling and likely drainage failure. Always strip the old lawn first.

What depth should my garden shingle be?

For decorative borders and paths, a depth of 40mm to 50mm is standard. Any deeper and it becomes difficult to walk through; any shallower and the weed membrane might become visible.

How much watering does new turf actually need?

In the first two weeks, you must water it every evening (and sometimes morning) until the water soaks through to the soil beneath. If the turf feels "spongy" to walk on, it is sufficiently hydrated.

Why is my shingle turning green or brown?

This is usually due to algae or silt buildup. Using a permeable membrane and ensuring good light levels helps, but shingle in shaded, damp areas will require an occasional wash or treatment with a pet-safe patio cleaner.
