Unsuitable For

The following list represents the kinds of applications that multi spar gravel may not be suitable for:

  1. 1
    Areas with fine plantings: If you have creepers or low-growing plants in your garden gravel can make it harder for these plants to thrive, as it may interfere with their root systems as they try to grow.
  2. 2
    Erosion control: On steep slopes or areas with significant inclines, the loose nature of the gravel can make it prone to movement which can be problematic on slopes.
  3. 3
    Play surfaces

Maintenance

Measuring for a gravel calculator

Multi spar gravel is generally low maintenance, especially when a heavy duty membrane is installed underneath to suppress weeds, with most work limited to raking and the occasional removal of debris. It is recommended to occasionally power wash the product in order to maintain its original colour and prevent the buildup of algae or moss. Natural quarry materials may also have dust which should be washed off with water during installation. For areas with heavy foot traffic, such as paths or footpaths, replenishing the chippings may be necessary over time to maintain depth and coverage.

Purchasing Tips

When purchasing multi spar gravel, consider the size options and quantity necessary for your project. Where available, it is cost-effective to request a sample to assess the stone's colour and quality against your design requirements. Also, consider the different sizes; for instance, multi spar gravel 20mm are typically used for driveways, while smaller multi spar gravel 10mm is better suited to footpaths.

Our gravel calculator will give you a quick and unbiased estimate for your project needs just by taking a few measurements of the space. It is one of the best and easiest ways to order the right amount and helps avoid shortfalls or over-spending. Purchasing a multi spar gravel 20mm bulk bag or ordering in loose loads can offer better value than purchasing in smaller quantities. Therefore, calculating accurately can save both time and money. It is also important to consider the delivery aspects, including vehicle access to the site. Additionally, you should check stock availability and factor in VAT and transportation costs if applicable.
