Abstract: A sand bunker construction having different porous layers that are built up upon the ground and internal drainage. The first layer is a layer of aggregate. The aggregate is gravel having an aggregate size large enough to avoid displacement from rain and irrigation spray. A porous matrix is placed upon the first layer. The porous matrix is made from gravel aggregate that is coated with a binding agent, such as asphalt, tar, or cement. The binding agent is added in amounts only sufficient to bind the aggregate. The result is a porous matrix having numerous voids between the various pieces of aggregate. A covering of sand is applied over the porous matrix. The sand fills the top voids in the porous matrix and buries the porous matrix. Due to the rough texture and porosity of the porous matrix, the porous matrix holds the sand in place and greatly inhibits erosion.
