Recycled concrete is also used to build retaining walls to control erosion. Additionally, it can be used to construct raised garden beds – which can improve water drainage and germination, and properly crushed and well-graded, recycled concrete can even be used for landscaping stone or for mulch!

Reclaimed concrete material (RCM) is sometimes referred to as recycled concrete pavement (RCP), or crushed concrete. It consists of high-quality, well-graded aggregates (usually mineral aggregates), bonded by a hardened cementitious paste. The aggregates comprise approximately 60 to 75 percent of the total volume of concrete.

Such open-graded (permeable) base courses are intended to serve as subdrainage layers in concrete pavements and as a capillary break that prevents liquid water from rising to the bottom of interior concrete slabs through capillary action in the base course. Open-graded bases are not as stable as densely graded, well-compacted, crushed stone bases.
