Decorative Slate Chippings & Paddlestones - 20 to 40mm

For something a little different, some great options are slate chippings or paddle stones.

They can be used in multiple ways, including building out your rock gardens, amongst alpines, for bordering paths or flower beds, and even as a topper for your plant pots. Gardenhub has a number of Welsh and Cumbrian slate chippings in either 20 or 40mm sizes, which all fit simply into both modern and classic gardens with minimal effort. For those with water features, slates can be very impressive additions, with the shape helping create definition to the surrounding areas with their changing colours and textures when either dry or wet.

As slates are by-products of the roofing industry, they perform excellently under high exposure to water, which brings out extra colours. Due to these characteristics, they can be used in multiple areas of the garden, either in dryer spots, or exposed to the elements, and can even be used in ponds as they are fish-friendly.

Are your decorative slate chippings natural or dyed?

All our slate chippings are natural in their beauty. This offers several benefits:

  • Authenticity: Natural untreated slate preserves the genuine and unaltered appearance of the stone, showcasing its true colours, textures, and patterns. This can add a unique and authentic touch to indoor spaces, particularly for those who appreciate the natural beauty of the material.
  • Non-Toxic: Untreated slate is free from any chemical treatments or additives that may be used in the processing or finishing of the stone. This makes it a non-toxic and environmentally friendly option for indoor use, ensuring a healthier indoor environment.
  • Retains Natural Properties: Untreated slate maintains its inherent qualities, such as its natural resistance to water, durability, and heat resistance. It has not undergone any artificial enhancements or alterations that may affect these properties.
  • Minimal Maintenance: Natural untreated slate typically requires minimal maintenance. It may need regular sweeping or vacuuming to remove debris and occasional mopping with a mild detergent to keep it clean. The absence of surface treatments or coatings means there is no need for resealing or special maintenance procedures.
  • Natural Aging and Patina: Over time, a natural untreated slate develops a charming patina and can age beautifully, adding character and depth to the surface. This natural ageing process can create a unique and distinctive appearance that enhances the overall aesthetic of the indoor space.

Are your decorative slate chippings suitable for use in landscaping projects?

Decorative slate chippings are well-suited for use in landscaping projects due to their unique characteristics and versatility. Here are some reasons why decorative slate chippings are suitable for landscaping:

  1. Aesthetic Appeal: Decorative slate chippings add a visually appealing element to landscaping projects. They come in various shades of grey, blue, purple, and other earthy tones, providing a natural and elegant look to outdoor spaces. The rich colours and texture of slate can enhance the overall aesthetics of gardens, pathways, or borders.
  2. Low Maintenance: Slate chippings are relatively low maintenance compared to other landscaping materials. They do not require regular watering, mowing, or trimming like grass or plants. Once installed, they retain their colour and shape for an extended period without much upkeep.
  3. Weed Suppression: When properly installed, decorative slate chippings act as a barrier against weed growth. They create a protective layer that prevents sunlight from reaching the soil, inhibiting weed germination, and reducing the need for weed control. This can save time and effort in maintaining a weed-free landscape.
  4. Water Drainage: The nature of the slate allows for good water drainage. Rainwater can easily permeate through the chippings and infiltrate the soil, helping to maintain healthy soil conditions and prevent water pooling or flooding. This is especially beneficial for areas prone to heavy rainfall.
  5. Versatility: Decorative slate chippings can be used in various landscaping applications. They are commonly used as ground cover for garden beds, borders, or pathways, providing a clean and well-defined look. Additionally, slate chippings can be used around water features, in rock gardens, or as decorative accents in landscape design.
  6. Longevity: Slate is a durable and long-lasting material. When properly installed and maintained, decorative slate chippings can withstand weather conditions, foot traffic, and other impacts without significant deterioration. They can retain their colour and appearance for many years, providing a long-term solution for landscaping projects.
  7. Environmentally Friendly: Slate is a natural stone, making it an environmentally friendly choice for landscaping. It is not chemically treated or processed, reducing the ecological impact associated with synthetic materials.

Before using decorative slate chippings in your landscaping project, consider the size and thickness of the chippings to ensure they are suitable for your intended use. It’s also recommended to prepare the site properly, including installing a weed membrane or landscaping fabric to further suppress weed growth.

Overall, decorative slate chippings offer a visually appealing, low-maintenance, and durable solution for various landscaping projects, adding beauty and functionality to outdoor spaces.
