Why Build Plantable Retaining Walls?

Plantable retaining wall designs offer the best of both worlds, MagnumStone’s proven strength and building solutions that recapture green space. The system’s large hollow cores offer exceptional horizontal and vertical drainage features that serve multiple purposes. They bolster the retaining wall’s efficient drainage capabilities to improve its strength and performance. Plants grow and flourish in the process, benefitting from water and nutrients that flow through the blocks before draining.

• Use MagnumStone’s top blocks to provide extra space for more topsoil atop the Plantable wall
• MagnumStone’s large hollow core blocks reduces cement usage and increases the amount of topsoil that can be added to the hollow core to promote more green space
• The canopies of greenery in Plantable walls reduce heat island effects of concrete surfaces and increase evapotranspiration
• MagnumStone’s hollow core blocks provide valuable LEED credits by reducing the carbon footprint of concrete and transportation emissions for completed projects

What Greenery Should Be Planted In These Applications?

Every project has different soil conditions and considerations that are unique to its location and climate. Using filter fabrics for Plantable retaining walls will eliminate soil migration to keep plants in the areas they’re intended to be.

It’s recommended to contact a local horticulturalist to find out more about which low maintenance plants, shrubs, small trees and flowers will grow best in your Plantable retaining wall.

Plantable Retaining Wall Design Considerations

• Global stability will always be a factor, especially with terraced and tiered retaining walls
• Looking at the local soils and surrounding areas
• How many terraces are required and for what purposes
• Tree / shrub root balls, how much space they require
