Marine construction of a seawall (bulkhead) requires quality materials, advanced technology, and experienced craftsmanship to prevent erosion and withstand strong winds and high waves. We encourage the installation of vinyl seawalls over conventional materials for increased longevity and environmental protection. We also offer Rip Rap or specially treated wood wall and will be happy to accommodate our customer as best as we can. At Dale’s Marine, we only use #316 high grade stainless steel tie-back rods to ensure outstanding strength and longevity. We ONLY use Everlast Synthetic Products vinyl sheet pile material. This is the highest quality vinyl material on the market today.
