What is a sea wall? Sea walls, often called bulkheads, can be a critical part of protecting your shoreline and upland investment. Many homes and businesses have to deal with erosion control and other waterfront environmental concerns. Having a sea-wall can provide the barrier you need to protect your property from the water. We use the best synthetic corrugated vinyl or modular block retaining wall products available utilizing hot dipped galvanized or stainless steel hardware. The finished product gives an aesthetically polished look your neighbors will envy, and you will sleep better knowing your yard is not sliding into the ocean!
