Permeable Concrete Retaining Wall | CornerStone 100
Permeable Concrete also known as no fines concrete was developed as an alternative to standard Concrete Masonry Units (CMU) and geogrid reinforced retaining walls. With No-fines permeable concrete the retaining wall blocks and concrete become one porous mass eliminating the need for costly rebar and geogrids which can demand a lot of excavation and backfilling.
The No-Fines concrete by itself is a permeable concrete that is made by removing the fine aggregates in concrete. Removing the fines adds significant voids within the concrete giving it a permeable structure.
No-fines concrete can reduces the amount of excavation by nearly 30%
