We sell our Blue Metal Pitching Rock (100–300mm) by the cubic metre, so the quantity you need will depend on the area to be covered and your installation depth.

To estimate the volume required, use the following formula:
Length × Width × Depth = Cubic Metres (m³)

Note: For erosion control projects, a deeper layer of rock may be required. If you're unsure, consult the professional assisting with your project or contact our friendly team for help calculating the quantity you'll need.

Yes. Blue Metal Pitching Rock is well suited to gabion baskets and walls. However, we recommend visiting our yard or contacting our office before purchasing, as the size distribution can vary between loads. This allows you to confirm that the current stock is suitable for your project.

When filling your gabion basket or wall, it's a good idea to sort the rocks by size. Position the more attractive rocks around the outside where they will be visible, then fill the centre with the remainder.

Note: This quarried rock is a natural product and may contain some stones under 100mm due to the processing and screening method. When using blue pitching rock in gabion walls or structures, we recommend sorting the stones—placing the largest rocks against the visible faces and using smaller pieces to fill the centre. This helps achieve a strong finish while making the most of your mix.

Note: Rock colours appear darker when wet. For an accurate shade, view them dry or ask our staff for dry samples or photos of the product when dry. If you receive a delivery when it is or has been raining, wait at least 24 hours of dry weather to view the true colour of your stones.
