If you are interested in a waterfront structure or shoreline protection project with Dale’s Marine Construction, please fill out our estimate request form.



Seawalls are a form of coastal defense to protect the area inhabited by people from tides, waves, and storm surges, as much as possible.

Marine construction of a seawall (bulkhead) requires quality materials, advanced technology, and experienced craftsmanship to prevent erosion and withstand strong winds and high waves. At Dale’s Marine Construction, we encourage the installation of vinyl seawalls over conventional materials for increased longevity and environmental protection. At Dale’s Marine, we only use #316 high-grade, stainless steel, tie-back rods to ensure outstanding strength and longevity. Moreover, we only use the highest quality vinyl material on the market today – Everlast Synthetic Products’ vinyl sheet pile material.

Furthermore, we also offer Riprap solutions or a specially-treated wood wall, which absorbs the waves and helps decrease the risk of erosion in the area. We do our best to accommodate each customer’s needs and requests.


Albeit gorgeous and one-of-a-kind, coastal living still comes with natural challenges, such as erosion, storm surges, waves, etc. Dale’s Marine Construction builds sturdy seawalls and riprap to help further protect your property and inhabited areas.

  • Designed to defend against natural phenomenons
  • Superior Quality and Craftsmanship
  • Improved material for greater longevity
  • Equipment to properly build seawalls and riprap


  • Why do I need a seawall? Can I simply use riprap instead?

    Although riprap prevents a lot of erosion, a seawall is the only way to ensure full protection of your property. As the water comes in, a lot of erosion can still occur with riprap when it surges through the rocks and filters the dirt. Thus causing more erosion of your property during these events.

  • Why should I choose your seawall designs over the competition?

    At Dale’s Marine, our walls are built with 0.35″ thick vinyl, which is very thick. To fully demonstrate the thickness and strength of the vinyl, our estimators carry samples on their trucks to show our customers and potential customers. Furthermore, we only use a minimum of 12’ long stainless-steel tie back rods, which are installed to 5’-6’ long deadmen poles with two 2” x 8” drag plates. When installing the vinyl, we install the sheets a minimum of 8’ in the ground; this process helps strengthen your wall’s abilities. Our goal is to build a strong wall that will not pull away during a storm, nor fail due to short sheets. In our years of experience in the marine construction industry, we have witnessed the common failure of walls with sheets that are too short or ones that were installed only 2′-4′ in the ground. Another reason for failure of the shorter walls is the sheets kick out at the sand line due to tidal changes over the years or they come straight out of the ground during a storm event. Although others in the industry may promote the smaller sheets and different install tactics, claiming that you do not need the length or depth that we use at DMC, we believe it is imperative to build a shoreline protection feature that has greater chance of protecting your property initially, rather than hoping it will resist the extremes of a storm or normal wear and tear.

  • If we have a swimming pool, does this require a stronger wall? How will the wall impact the integrity of our pool?

    Understanding the interaction and implication of a seawall alongside a swimming pool is very important; both are property enhancements and features that you want to protect and maintain confidence they are constructed correctly. We have an exceptional amount of experience working around swimming pools with our construction projects. Our foremen work directly with the pool company to ensure the exact placement of the tie-back rods correctly correspond with the integrity of the pool. If your future plans include the installation of a pool, please make sure your estimator is aware of that when you start the planning process; this will allow us to quote and design the wall’s construction accordingly. At DMC, we strongly recommend constructing a wall “Navy-style” when it is next to a pool or the future location of a pool. The “Navy-style” consists of the pilings being installed in front of the wall to provide more strength and support. The weight of the pool can cause a wall to collapse or fall out if it is not properly supported, which is why we strongly encourage this style.
