Remove decking & lay gravel.

This project involves more than just swapping materials; it requires careful ground preparation to ensure the new driveway doesn't sink or become a haven for weeds. Whether you are looking to create space for a second car or simply want a lower-maintenance front garden, understanding the process and costs is essential for a successful renovation.

What Does the Work Involve?

• Decking Dismantling: Systematically removing deck boards, joists, and any supporting posts or concrete "shoes" to clear the footprint.
• Waste Management: Sorting timber for recycling or disposal and hiring skips to remove debris from the site.
• Ground Excavation: Removing turf, soil, and organic matter to a depth of roughly 150mm to 200mm to accommodate the new base.
• Sub-base Installation: Laying and compacting a layer of MOT Type 1 crushed stone to create a solid, load-bearing foundation.
• Edging Restraints: Installing timber sleepers, brick paviours, or metal edging to keep the gravel contained and prevent "migration."
• Membrane Laying: Fitting a heavy-duty geotextile weed membrane to prevent soil mixing with the gravel while allowing water to drain.
• Gravel Application: Spreading the chosen decorative aggregate (usually to a depth of 40mm to 50mm) and leveling for a neat finish.

Typical Costs

Prices for this project vary based on the size of the area, the type of gravel chosen (e.g., standard pea shingle vs. decorative Cotswold stone), and the volume of waste to be removed. The following table provides estimated costs for 2025/26, including VAT.

The primary cost drivers are waste disposal and site access. If your garden is tiered or has restricted access, manual handling will significantly increase the labour hours required. Choosing a premium "self-binding" gravel or bespoke edging will also push costs toward the higher end of the scale.

How Long Does It Take?

• Small Projects (Up to 15m²): 1–2 days. This covers deck removal on day one and ground prep/gravel on day two.
• Medium Projects (30m²): 3–4 days. Extra time is needed for more extensive excavation and larger volumes of material.
• Large Projects (60m²+): 5+ days. Often involves heavy machinery (mini-diggers) and multiple skip exchanges.

DIY or Professional?

While removing a deck is a manageable DIY task for those with a crowbar and a saw, installing a driveway is physically demanding work that requires precision. A poorly laid sub-base will lead to ruts and "sinking" under the weight of a vehicle within months. Professionals also have access to plate compactors (wacker plates) and skip accounts, which are essential for a long-lasting finish.

Expert Tip: If you are using the area for a vehicle, never skip the sub-base. Laying gravel directly onto soil or sand will result in a muddy mess after the first heavy UK downpour.

Choosing the Right Tradesperson

• Check Waste Licenses: Ensure the landscaper holds a valid Environment Agency Waste Carrier License to avoid "fly-tipping" liability.
• View Portfolios: Look for previous gravel driveway projects to see how they handle edging and drainage.
• Request a Detailed Quote: Ensure the quote specifies the depth of the sub-base and the grade of the weed membrane.
• Questions to Ask:
  • "How deep will you excavate the area?" (Should be at least 150mm for vehicles).
  • "What type of edging do you recommend for this specific stone size?"
  • "How will you manage drainage to ensure the driveway is SuDS compliant?"

UK Regulations

• SuDS (Sustainable Urban Drainage Systems): Since 2008, UK law requires new driveways to be permeable. Gravel is naturally compliant, meaning you usually don't need planning permission.
• Dropped Kerbs: If you are creating a new access point to a public highway, you must apply to your local council for a dropped kerb; this is a separate legal requirement.
• Waste Transfer Notes: You should receive a note from your contractor proving that your old decking was disposed of at a licensed facility.

Common Problems

• Gravel Migration: Without proper edging, gravel will spill onto the pavement or into your lawn. Always insist on a robust border.
• Sinking and Rutting: This happens when the MOT Type 1 sub-base is too thin or not compacted properly with a heavy-duty plate compactor.
• Weed Growth: Using a thin, "polythene" style sheet instead of a heavy-duty woven geotextile membrane allows weeds to pierce through from below.
• Wrong Stone Size: Stones smaller than 10mm can get stuck in tyre treads, while stones larger than 20mm are difficult to walk on. 20mm is the industry standard for driveways.
