Custom Dock Building & Marine Construction on the Grand Strand
Most homeowners who call us have already spent a few months trying to figure out where to start. They've gotten one quote that felt too vague, looked at a few photos online, maybe talked to a neighbor who had work done three years ago. By the time they reach us, the main thing they want is someone who can explain what actually needs to happen — not just hand them a number.
That's how we approach every project. We walk your waterfront, look at what you're working with, and tell you what makes sense for your specific site. The right dock for a tidal creek lot in Murrells Inlet looks very different from the right dock for an ICW-front estate in Grande Dunes. Same coast, completely different engineering requirements.
Myrtle Beach Elite Dock Building handles custom dock construction and full marine builds across Horry and Georgetown counties. We work with residential homeowners, vacation property owners, and commercial waterfront operators. Our crew manages everything in-house — OCRM permitting, site prep, pile driving, framing, decking, mechanical installs, and electrical. No fragmented subcontractor chains. One crew, one timeline, one point of contact from permit application to final walk-through.
Here's what we build.
Our Dock Building & Marine Construction Services
The services below make up the core of what we do.
Some projects involve just one of these.
Most involve several working together as part of a complete waterfront build.
Cantilevered Dock Construction
A cantilevered dock extends outward over the water without vertical support posts underneath the main platform. Instead, the load transfers back through the frame to the piling foundation behind it. The result is a clean, open underside — no posts breaking up the water access, no obstructions for boats maneuvering underneath, and no hardware sitting in the tidal zone where corrosion starts early.
Cantilevered designs are common in areas with significant tidal swing, heavy boat traffic, or waterways where submerged pilings would create navigation hazards. They're also the right call in certain permit scenarios where OCRM restricts the number of vertical structures you can place in a navigable waterway.
The engineering on a cantilevered dock has to be done correctly. The moment arm — the distance the platform extends beyond its support point — determines the load requirements on the frame and the piling system. We size both to handle not just standard foot traffic and boat activity, but the added stress of storm surge and wind-driven wave loads.
One project in Garden City a few years back illustrated why this matters. The previous dock had been cantilevered by a contractor who underbuilt the back-span connection. Three years in, the platform had developed a noticeable forward tilt. The piling was fine. The framing connection had simply never been adequate for the span. We rebuilt the frame from the attachment point out and the issue was resolved — but it was a repair bill that could have been avoided with proper engineering up front.
If you're considering a cantilevered design for your property, the starting point is a site assessment to determine your span requirements, water depth, and tidal range. We take those measurements before anything gets designed.
Tidal Dock Engineering & Build
The majority of residential and commercial dock builds along the South Carolina coast are tidal fixed-pier docks — stationary structures built on driven pilings, designed to handle the regular rise and fall of coastal tidal cycles. This is the standard dock type in our market, and it's what most property owners picture when they think about a traditional waterfront dock.
Getting the elevation right is the most important decision in a tidal dock build. The deck height needs to clear your mean high water mark with enough freeboard to keep the platform dry under normal conditions, while remaining accessible at low tide without a ladder. In areas with a two-to-four foot tidal range — which covers most of the Grand Strand — that calculation needs to account for seasonal variation, storm surge potential, and the specific hydrological conditions at your site.
We've seen docks built at the wrong elevation on both ends. Too low and the platform floods every spring tide, accelerates wood decay, and eventually becomes unusable. Too high and you end up with an awkward step-down to your boat at low water that defeats the purpose of having a dock in the first place.
Tidal dock engineering also covers the pile spacing, framing layout, decking material selection, and the connection hardware — all of which affect long-term performance in a salt and humidity environment. We use corrosion-resistant hardware throughout and build every tidal dock to the applicable OCRM setback and structural requirements for permitted construction in South Carolina.
Floating Jet Ski Port Assembly
Personal watercraft ownership on the Grand Strand has grown steadily over the last decade, and floating jet ski ports have become one of the most requested dock accessories we install. They make sense for this coastline — easy boarding and exit, self-draining design, and they handle the constant up-and-down of tidal movement without requiring any adjustment from the owner.
A floating jet ski port connects to your existing dock or bulkhead through a mounting bracket system and rides the tide independently. The platform stays at water level regardless of where the tide is, which means you're not wrestling your PWC onto a high platform or low-wading to get to it. For properties with regular recreational use, that convenience matters.
We handle the full assembly — float selection, connection hardware, anchor positioning, and integration with your existing dock infrastructure. The mounting system needs to be matched to your specific dock design and the water conditions at your site. A floating port that's rigged correctly on a calm canal will behave differently in an area with strong tidal current or frequent boat wake, and the anchor system needs to account for that.
If you're adding a jet ski port to an existing dock, we'll assess the connection point and make sure the mounting hardware is appropriate for your dock's current structure. Adding weight and lateral load to an aging dock without checking the attachment point first is a shortcut that creates problems.
Floating Dock Anchor System Installation
A floating dock is only as reliable as its anchor system. The float itself is the part people see and use — but what keeps it positioned correctly, prevents it from drifting under load, and manages the stress of tidal movement and wave action is the anchor system underneath.
In South Carolina coastal conditions, floating dock anchors typically take one of a few forms: driven steel pile guides that allow the float to ride up and down a fixed piling, deadweight concrete anchors on chains, or helical anchor systems driven into the bottom substrate. The right choice depends on your water depth, bottom composition, tidal range, and whether the site is exposed to significant wave or current load.
We design and install the full anchor system as part of any floating dock project. For existing floats that have started to drift, list, or swing more than they should, anchor system assessment and repair is a standalone service. A dock that's pulling at its anchors awkwardly puts stress on both the float frame and the connecting hardware — and that stress compounds over time.
One thing we see fairly regularly: floating dock anchors that were correctly sized when the dock was installed but never serviced after years of bottom sediment shift, chain wear, or corrosion on the piling guides. An anchor system that's worked fine for ten years can fail relatively quickly once the components start going. Periodic inspection is worth building into your maintenance routine.
Aluminum Gangway Installation
The gangway is the transition point between dry land — or your fixed pier — and the floating portion of your dock. It's the piece that makes everything functional, and it's also the piece that takes the most abuse. Every time someone steps onto the dock, they cross the gangway. Every tidal cycle, it adjusts angle. Every storm, it absorbs movement from both ends.
Aluminum is the right material for this application on the Grand Strand. It handles salt exposure without the ongoing maintenance that steel requires, it's lightweight enough to move if necessary, and modern aluminum gangway systems are built with anti-slip grating surfaces that stay safe when wet — which on a tidal dock is most of the time.
We install gangways ranging from standard residential widths up to heavy-duty commercial configurations. The installation includes the wall or pier mounting bracket, the floating dock attachment, the grating surface, and the handrail system. Length and pitch need to be sized for your specific tidal range — a gangway that works fine at mid-tide shouldn't be at a dangerous angle at extreme low water.
ADA-compliant gangway configurations are also available for properties that require accessible water access. The slope requirements for ADA compliance add some length to the span, but the engineering and hardware are straightforward and we handle the documentation for permit purposes.
Covered Boat Slip Roofing Construction
A covered boat slip adds a structure above the dock platform to shelter a berthed boat from direct sun, rain, and storm debris. In the South Carolina coastal climate, UV degradation and heat exposure do real damage to boat finishes, canvas covers, and onboard electronics. A covered slip significantly extends the time between detailing and reduces wear on components that are expensive to replace.
The roofing structure itself is vertical construction added to the dock's piling system — typically a hip or gable roof framed in marine-grade aluminum or treated timber, finished with metal roofing panels or polycarbonate roofing sheets depending on the aesthetic preference and budget. The framing has to be engineered for wind uplift loads. A coastal roofing structure that isn't properly tied down to the piling system becomes a liability in a strong storm.
We build covered slips as part of new dock construction and as additions to existing structures. When adding a roof to an existing dock, the first thing we assess is whether the existing piling system is adequate to carry the added lateral load from wind on the new structure. Pilings that were driven for a standard open deck platform aren't always appropriate for a covered slip without supplemental support.
These structures also require their own permitting review with OCRM. We manage that process and know what the reviewers look for in terms of structural documentation and setback compliance.
Hydraulic Boat Lift Installation
A hydraulic boat lift holds your boat above the waterline when it's not in use — which is exactly where you want it in a tidal salt-water environment. Sitting in the water accelerates hull fouling, corrodes underwater hardware, and puts ongoing stress on the boat's waterline paint and gelcoat. A lift eliminates all of that.
Hydraulic systems are the preferred option for larger vessels where the lifting capacity requirements exceed what a standard cable lift can handle reliably. They're also quieter, smoother in operation, and require less frequent cable maintenance than cable-driven alternatives. For center-console boats, bay boats, and larger recreational vessels common in the Grande Dunes and Briarcliffe waterfront markets, hydraulic lifts are the standard specification.
Installation involves the lift frame, the hydraulic drive unit, the electrical connection, the control system, and the integration with your dock's structural layout. The lift needs to be positioned so the boat floats onto the cradle correctly at water level and lifts cleanly without contact with the dock framing. Getting that geometry right requires accurate measurements of both the boat and the slip configuration.
We size every lift installation to the specific vessel — not to a round number that "should be enough." If you're planning to upgrade your boat in the next few years, that's worth factoring into the lift specification now rather than replacing hardware twice.
Cradle Lift Cable Rigging & Installation
Cradle lifts use a cable and winch system to raise and lower a boat on a V-shaped cradle. They're the standard choice for smaller vessels, personal watercraft, and applications where hydraulic systems are oversized or impractical. In shallow-water environments like the Cherry Grove canal system and parts of the Murrells Inlet tidal creek network, cradle lifts are often the only lift type that works within the available water depth.
The rigging is the part that determines long-term reliability. Cable material, routing geometry, pulley placement, winch capacity, and the connection points on the cradle frame all affect how the system performs under load and how long it holds up in a marine environment. Poorly rigged cable lifts wear unevenly, develop slack and binding problems, and eventually fail at the points of highest stress — usually the cable terminations or pulley attachments.
We rig cradle lift systems from scratch and rebuild existing rigging that's showing wear. A cradle that's pulling unevenly, lifting with a tilt, or making noise at the winch under load has a rigging problem that gets worse with use. Addressing it early is a straightforward job. Addressing it after a cable failure with a boat in the cradle is a different conversation entirely.
Heavy-Duty Fender & Bumper Installation
Fenders and bumpers protect the dock from boat contact — the constant, low-energy impacts of docking, the harder contact in choppy conditions, and the lateral pressure of a boat sitting against a cleat in wind or current. Done right, a good fender system protects both the dock framing and the boat hull. Done wrong, it protects neither.
Heavy-duty marine fenders on the Grand Strand need to be rated for UV exposure and salt immersion without degrading over a two-to-three year service period. Low-grade foam or rubber products that look fine in a catalog frequently crack, compress permanently, and fall apart within a year or two in direct coastal sun. We use commercial-grade fender and bumper products throughout.
Installation placement matters as much as the hardware itself. Fenders need to be positioned where the boat actually makes contact — which varies by vessel type, dock configuration, and whether the boat is approaching the slip bow-in or stern-in. We walk through your vessel and your typical docking approach to position bumper hardware where it will actually be effective.
Fender pile wraps, corner guards, and slip entry bumpers are all part of our standard finishing scope on new dock construction. For existing docks where the fender system is worn out or was never adequate, this is a fast, straightforward upgrade that makes a real difference in daily use.
Integrated Marine Lighting Installation
Dock lighting serves two functions: it makes the dock safe and usable after dark, and on a well-designed waterfront property, it looks genuinely impressive. Both matter to our clients.
Marine lighting installations on the Grand Strand are almost always LED-based at this point. The combination of energy efficiency, longevity, and resistance to vibration and moisture makes LED the clear choice for an outdoor environment with constant salt air exposure. We use marine-rated fixtures throughout — not standard outdoor lighting that happens to be mounted near water.
A complete marine lighting system typically includes pathway lighting along the dock surface for foot traffic safety, underwater dock lights that illuminate the water column below the platform, and piling or post-mounted uplights for the overall dock structure. Some clients add lighting under a covered slip ceiling, integrated rope lighting along railings, and coordinated controls that let the whole system run on a timer or a single switch.
The electrical work on a marine lighting installation runs back to a properly rated panel with GFCI protection throughout. All wiring, conduit, and connection points are sealed for moisture exposure. OCRM doesn't govern the electrical components of a permitted dock directly, but the National Electrical Code requirements for boat dock wiring are specific — we build to those standards on every install.
Underwater dock lights in particular transform the look of a waterfront property at night. If you've seen them on a neighbor's dock and wondered what they cost to add, it's usually a more accessible upgrade than people expect.
What the Build Process Looks Like
We don't do ballpark quotes over the phone for dock construction. The site conditions, tidal data, permitting requirements, and your specific design needs all affect the project scope in ways that a general estimate doesn't capture.
Here's how a typical project moves from first contact to finished dock.
Site Assessment
We come to your property, walk the waterfront, and document water depth, tidal range, bottom substrate, existing structures, and setback conditions. This takes an hour or two and gives us everything we need to design accurately and permit correctly.
Design & Permit Application
We develop the structural design and submit the OCRM permit application on your behalf. DHEC permit review typically runs eight to sixteen weeks depending on project type and current workload. We submit complete documentation to avoid back-and-forth delays.
Permitting follow-through
We track your permit status and respond directly to any reviewer requests for additional information. You don't need to manage that process.
Construction
Once the permit is in hand, we schedule your build. Pile driving, framing, decking, mechanical systems, and electrical all run in sequence with our in-house crew.
Final Walk-Through
We go over every element of the finished structure with you, explain how the mechanical and electrical components operate, and confirm everything is built to spec before we call the project complete.

Frequently Asked Questions
How long does it take to get a dock permit in South Carolina?
OCRM permit review typically runs eight to sixteen weeks from the date of a complete application submission. Projects involving marsh impacts, navigable water crossings, or larger commercial structures may take longer. We submit thorough documentation upfront to minimize the chance of delays from reviewer requests for additional information.
Do I need a permit to build a dock in Myrtle Beach or Murrells Inlet?
Yes. Any structure built over coastal waters in South Carolina requires authorization from OCRM under the jurisdiction of DHEC. Depending on your site, you may need a Navigable Waters permit, a CAMA permit, or both. We manage the full permitting process for every project we build.
What's the difference between a cantilevered dock and a standard tidal dock?
A standard tidal dock sits on vertical pilings driven through the water and into the bottom substrate. A cantilevered dock extends over the water without pilings under the main platform — the load transfers back to a foundation piling behind the structure. Cantilevered designs are better suited for areas with navigational restrictions, significant tidal range, or situations where a clean open underside is preferred.
How do I know if a hydraulic lift or cradle lift is right for my boat?
Boat size and weight are the primary factors. Hydraulic lifts are better suited for larger, heavier vessels — typically anything over 3,500 to 4,000 pounds or longer than 24 feet. Cradle lifts handle smaller boats and personal watercraft well and are also the practical choice in shallow-water locations where a hydraulic system won't have the clearance it needs. We size every lift to the specific vessel rather than a general capacity range.
Can a covered boat slip be added to an existing dock?
Yes, in most cases. The key condition is whether the existing piling system is adequate to carry the added lateral wind load from the roof structure. We assess the current piling capacity before recommending an addition. If supplemental pilings are needed, we include that in the scope.
What decking material is best for a dock in coastal South Carolina?
Composite decking is the most practical long-term choice for most homeowners. It handles the salt, humidity, and UV exposure that accelerates the degradation of pressure-treated pine, and it doesn't require the sealing and staining schedule that hardwood options like Ipe demand. Ipe is an excellent material if you want the natural wood aesthetic and are willing to maintain it — it outlasts standard wood by a wide margin but does require periodic treatment to stay in top condition.
What is marine piling encapsulation and do I need it?
Piling encapsulation involves wrapping existing pilings in a protective fiberglass or polymer shell that seals the wood against marine borer activity, salt exposure, and freeze-thaw cycling. It's not always necessary on new construction where treated pilings are freshly driven, but it's a strong investment on older pilings that are beginning to show surface degradation. It significantly extends piling life without requiring full pile replacement.
How is a floating dock different from a fixed tidal dock?
A fixed tidal dock sits at a set elevation relative to mean high water — it doesn't move as the tide changes. A floating dock rides the tide and stays at or near the water's surface at all times. Floating docks are better for frequent boarding and exiting, personal watercraft use, and locations with large tidal swings where a fixed platform would be impractically high at low tide. The right choice depends on your site conditions and how you use the dock.
Do you handle marine lighting electrical work, or do we need to hire a separate electrician?
We handle the complete marine lighting installation including all wiring, conduit, junction connections, and GFCI panel integration. Marine electrical work requires specific knowledge of NEC boat dock wiring standards — it's not the same as standard residential outdoor lighting. We build to those standards on every install.
What maintenance does a dock typically need after it's built?
The maintenance schedule depends on your materials. Composite decking requires very little — occasional washing and hardware inspection. Ipe hardwood needs periodic oiling to maintain its surface and prevent checking. Mechanical systems like boat lifts and cradle rigging should be inspected annually for cable wear, pulley condition, and hardware corrosion. Piling caps and fender hardware are worth checking after any significant storm event. We can walk you through a site-specific maintenance checklist when we do your final walk-through.
