What is it

Imported granular fill is off-site sourced stone or recycled aggregate delivered, spread in layers and compacted to form stable sub-bases, platforms or make-up levels.

Rate guide
Standard well-graded imported fill, normal access£61 – £88/m³
Recycled 6F2 or equivalent general fill£46 – £72/m³
Type 1 granular sub-base£72 – £105/m³
Clean crushed stone or low-fines fill£83 – £121/m³
Small quantity or restricted-access placement£105 – £160/m³
Labour output
Open platform, continuous deliveries and good plant access180–300 m³/day
Typical building site with routine trimming and compaction100–180 m³/day
Confined working area with limited stockpiling50–100 m³/day
Broken-up pours, obstructions or restricted plant access20–50 m³/day
Key rate adjusters
Haul distance
Longer aggregate journeys and urban delivery constraints typically add £5–£20/m³.
Material specification
Certified Type 1, clean stone or tightly graded material can increase the fill rate by 15%–40% against general recycled fill.
Layer thickness
Thin lifts requiring repeated spreading and rolling can increase placement costs by 10%–25%.
Testing regime
Density testing, proof rolling and additional compliance records commonly add £2–£6/m³.
Site access
Restricted tipping, vehicle marshalling or rehandling can increase the overall rate by 20%–50%.
Order size
Small or intermittent quantities can attract minimum-load and plant-standing uplifts of £10–£30/m³.
Quantity surveyor insights
  • Waste and buildability: Allow 5%–10% for compaction, trimming and local overdig, with a higher allowance where formation levels are irregular or the fill must be double-handled.
  • Scope and procurement: Confirm whether the package includes geotextile, formation preparation, testing, proof rolling and disposal of rejected material; secure delivered aggregate quotes early because haulage capacity and local quarry availability can materially alter the tender allowance.
