Long Rake Spar White Cobbles - 40-90mm - 20kg Poly Bag

For a pathway, first lay a weed membrane, followed by a layer of crushed stone or gravel (approximately 50-75mm deep) compacted well. Then, spread the cobbles evenly over the prepared base to your desired depth.

Coverage varies depending on the desired depth and how tightly the cobbles are laid. As a general guideline, a 20kg bag might cover approximately 0.2 to 0.3 square meters at a depth of 40-50mm.

While they are natural stone, it's always best to check if the specific type of stone is inert and safe for aquatic life before using them in a fish pond. Rinsing them thoroughly before use is recommended.

Yes, you can mix them with other aggregates for a unique decorative effect. Consider the size and colour contrast for the best visual outcome.

For light algae, a stiff brush and water may suffice. For tougher stains, a diluted solution of white vinegar or a specific patio cleaner designed for natural stone can be used, followed by a thorough rinse.

The white colour significantly enhances the visual appeal, reflecting light and creating a bright, clean, and sophisticated look in landscaping projects, making spaces appear larger and more luminous.

The natural shine of the cobbles is more apparent when wet. Once dry, they will return to their natural finish. Regular cleaning can help maintain their appearance.

Ensure a high-quality weed membrane was installed beneath the cobbles during setup. If not, carefully remove weeds and consider installing a membrane for long-term prevention.

This indicates an insufficient base. The area may need to be dug out, a proper sub-base of aggregate laid and compacted, and then the cobbles re-laid.

Use a rake to gently level the cobbles, ensuring a consistent depth. Avoid overworking the cobbles, which can lead to chipping.
