Ocean Shell has been aged for 12-18 months which removes all unpleasant odours. Wholesale Landscapes allow a natural bacterial process to remove any by-product from the shell whilst it is monitored and turned. During this process, the sharpness of the mussel shell reduces significantly which provides a safe surface for your horse.


Natural trace elements contained in the shell base, such as lime and calcium, will improve horse’s hoof health, making them less susceptible to injury or disease. Ocean Shell is not only a great horse arena surface but also helps retain moisture which increases the effectiveness of irrigation for landscaping. Ocean Shell allows plants to flourish without fighting for nutrients due to its weed-suppression properties.


Its white colour also reduces the risk of pests through providing light reflectiveness under and around plants. All Ocean Shell products are organic-compliant and are acceptable for use in certified-organic areas


*Due to the deodorising process, there may be a slight risk of large stone contamination, important to check and remove prior to use.

Recommended depths

Typically you need a finishing layer of screened soil of 100mm when working with an uneven surface. 100mm of soil will allow to even out any hollows and give enough depth to create a flat surface

A general rule for compost is to allow for the depth of the current root structure of your plants with an additional 30-50% to mix in with the base. If you’re planting into holes or filling up a vege garden  you will need to accommodate for this prior to filling up

We recommend 100mm (10cm) deep for new bark gardens and planting into bare areas. For existing gardens with some cover, we recommend 75mm-100mm (7.5cm-10cm)

Note: Barked areas for playground impact protection need to meet NZS5828:2015 standards and is calculated on the fall areas and the height of the playground. Please contact us to discuss your barked playground areas

For paths and driveways which are often exposed to car and foot traffic, we recommend 100mm-125mm (10cm-12.5cm) on newly prepared areas due to settling of product.

This excludes preparation, compaction or drainage gravel underneath. For existing areas 75mm thickness is recommended for areas needing a small top-up.
