Sandstone boulder retaining walls have many advantages. One of the major advantages is that they are durable. They don’t rot or get infested by termites.
This project involved replacing a log retaining wall which had failed.
The inherent mass of a correctly designed boulder wall means that the wall simply won’t fail if the foundations have been correctly constructed and the aggregate drainage layer has been established behind the boulders.
This new sandstone boulder wall was engineer-certified and as Cornerstone Boulder Walls is a QBCC licensed contractor, the owners have peace of mind.
