No. The difference between the Superior Concrete Walls System and other precast concrete fences is that the other companies use old technology. While they all cast there panels on the ground, lift them up and fix them together, Superior Concrete Walls employ the latest American technology using a machine that is known as a Vertical Battery Mould. This machine repetitively produces quality precast concrete wall components. Rather than fixing our components together (which can fail over time) all our components interlock together as with tongue and groove.
