When building projects for our clients, we take into consideration everything that will make their landscape stand the test of time. In the pictures that follow , Davison's is using geogrid to help "tie" the wall back and stabilize the backfill. What do you mean by that?
What I mean is this; Say we were to take the wall itself out of the equation, technically the geogrid and backfill should remain in place. Therefore its still a functioning wall, just without the veneer of the block. Geo grid has been around since ancient times. The Romans used it in road building and their complex structures. It was made out of
Another consideration is water and how do we get rid of it the fastest. Water in a hardscape is your enemy "most" of the time. It will erode, corrode, and help push
( freeze/ thaw) your expensive project over or down. By getting rid of the water, you are raising the longevity of the project.
Our footer or base of the wall is well thought out by us or an architect. If there is insufficient base material put down and it's not compacted thoroughly, the wall will fail. All of Davison's retaining walls, no matter how small , we use separation fabric or more commonly said in the industry "geofabric" between the footer and the undisturbed soil beneath. This serves a two-fold purpose, one it keeps the base material (usually crushed limestone call four eleven) from mixing in with the subsoil. If it mixes with the subsoil , integrity of the compaction could be compromised. Secondly, the geofabric acts as a bridge. If there's settling that occurs from trenches or organic matter breraking down, it will straddle the void like a bridge does and keep the settling from transferring upwards.
