Planning gravel driveway repairs
A gravel top-up should replace the missing surface depth without burying a failing foundation. Raking and redistribution may reduce the quantity required.
The example bag covers about 14 m² at 40 mm for the named supplier’s gravel. Replace the bag price or coverage to match your supplier.
Measuring the work for this calculator
The calculator converts area and layer depth to the equivalent coverage of the selected example bulk bag, adds your material allowance and rounds up to whole bags. Coverage and bag price are prefilled examples that can be changed to match a supplier.
What the gravel driveway repairs estimate covers
The displayed bag cost is a supply-only example. Delivery, labour, excavation, plant, disposal and rebuilding failed supporting layers are excluded unless you enter an additional allowance. A supplier’s delivered quote may use a different bag size or bulk-load price.
The first guide option is example 850 kg gravel bulk bag. Its allowance is £142 for the relevant unit shown in the result. This is a published-guide starting point; it is not a price offered by a contractor on this website.
Choose the specification and separate allowances
This page models example 850 kg gravel bulk bag. A different construction or repair method needs a separate allowance rather than an assumption that every job has the same scope.
The project controls include:
- Average top-up depth (mm).
- Example bag coverage at 40 mm (m²).
- Material allowance (%).
Reading the budget breakdown
The results show the measured quantity, the selected work allowance and any separately selected items. A volume, unit count or coverage result is a quantity check, not a construction design. Where the model uses a minimum visit allowance or whole bags, the displayed total will not fall in direct proportion to a very small area.
Use the optional contingency to make a separate budget provision. Add a quoted fixed allowance only for work outside the model’s stated scope. Check the VAT basis before selecting the VAT adjustment.
Compare quotations for gravel driveway repairs
Give contractors the same measurements and work description. Ask them to identify the main work, preparation, disposal, access requirements, drainage and any making-good that applies to this project. An apparent saving can simply mean that a different part of the scope has been priced.
The example bag covers about 14 m² at 40 mm for the named supplier’s gravel. Replace the bag price or coverage to match your supplier. Keep the agreed specification with the quote, including any exclusions and the way changes discovered during the work will be authorised.
