What type of foundation does Sound Bulkhead build its walls upon?
Sound Bulkhead sets base rock in a trench or key-way which provides lateral support for the toe of the bulkhead. Since water scour and undermining is a major consideration for all types of bulkheads, the depth required for maximum protection may vary according to soil conditions. Exposed embankment is minimized as soils are replaced with rock in short segments during excavation. This process protects against bank failure during construction.
