The 180mm Chestnut Brown Corner and Pillar is for use with the Brandon wall. Replicate the appearance of masonry in your landscape design with the Brandon collection. This classic collection offers the aesthetic appeal of brick garden walls while providing the added functionality of a double-sided, easy to install interlocking retaining wall system. It is a multi-length system available in two heights packaged separately, 90 mm and 180 mm, allowing for modular or linear designs. These designs can be used to build a retaining wall against soil erosion, create raised planters or subtly separate spaces when used as a decorative blade wall.
