Landscaping Applications

When it comes to landscaping, 10mm gravel is an economical material with a wide range of uses. Its size, shape and texture make it a solid choice for various outdoor projects, adding both functionality and a natural look to your outdoor spaces. Here are some typical landscaping applications for 10mm gravel:

  1. 1
    Walkways: Quartz gravel can be used to create natural-looking and functional pathways and walkways in gardens, parks, or around your home. Its small size provides comfortable walking while packing well and facilitating water drainage.
  2. 2
    Driveway: While it can be used as a decorative topping for driveways, 20mm gravel provides a more stable surface. Plus, the stones won't get stuck in your tyre treads, which can happen with the 10mm size!
  3. 3
    Garden Borders: Gravel can be used to create decorative borders around flowerbeds, shrubs, or trees. It provides a clean and defined edge and performs a range of tasks that minimise maintenance.
  4. 4
    Decorative Features: Incorporating 10mm pea gravel around fountains, garden ponds, or as a decorative mulch in planters conveys a natural appearance that complements various landscaping elements.
  5. 5
    Landscaping Features: Quartz gravel can be creatively used to construct dry riverbeds and rock gardens or fill gaps between stepping stones or pavers, contributing to the overall visual appeal of your landscape.
  6. 6
    Erosion Control: Gravel is a vital aggregate for managing erosion. When combined with grids or matting, it stabilises slopes and prevents soil erosion.

Construction Applications

Beyond its landscaping applications, 10mm gravel plays a crucial role in construction and building projects. Its durability and versatility make it an excellent choice for several construction purposes:

  1. 1
    Base Material: When compacted, crushed gravel serves as a robust sub-base for foundations and construction projects. It ensures stability, good drainage and longevity for these structures.
  2. 2
    Concreting: Mixing gravel with concrete creates a strong and durable concrete mix while significantly reducing costs.
  3. 3
    Filtration Media: As a medium used in filtration systems, including septic systems, stormwater management, rain gardens, wastewater treatment plants, pond filtration, and agricultural drainage, its role in these systems involves trapping sediments and pollutants, promoting natural filtration, and aiding in the removal of impurities and debris from the water.
  4. 4
    Soakaway: Pea gravel is an essential component in soakaway systems, helping manage excess rainwater by efficiently allowing it to infiltrate the ground. It acts as a reservoir, gradually releasing water and reducing the risk of flooding and erosion. Proper installation and layering are essential for optimal performance.
  5. 5
    Drainage: In drainage systems, whether standalone or in French drains, 10mm gravel facilitates water drainage, preventing waterlogging and soil saturation.

    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
    Driveways, particularly with high-traffic
  3. 3
    Play surfaces

Washing garden stones with a hose

10mm pea 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 gravel may be necessary over time to maintain depth and coverage.

Purchasing Tips

When purchasing 10mm gravel, consider the size options and quantity necessary for your project. Consider the size; for instance, 20mm gravel is typically used for driveways, while smaller 10mm and 6mm gravel 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 pea gravel 10mm bulk bag or ordering in loose loads offers 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.
