  • Open face application requires less blocks per metre squared therefore it’s more cost competitive than closed face retaining block applications.
  • Nib ensures a maximum angle of inclination of 70 degrees.

  • Unique design allows for plants to be part of the wall.
  • No mortar is required resulting in Terraforce being cost effective.
