A composite dock ends the maintenance cycle: no sealing, no staining, no splinters, no gray-out — soap and water, done. Jordan Marine Construction builds composite docks across Lake Conroe, Lake Livingston, and the Houston Gulf Coast, pairing marine-grade driven foundations with MoistureShield decking, the composite rated for ground and water contact.
That rating matters: most composite brands are warranted for above-ground use only, which a dock is not. We standardized on MoistureShield because its solid-core boards are engineered for exactly the exposure a dock lives in — and with 40+ years of construction experience, we build what's under the boards to match.

- 1
Design & Material Selection
We design the dock and help you select the MoistureShield line and color — including the Vision series — for your build.
- 2
Permitting
We coordinate the permit with your waterbody's controlling authority as part of every project.
- 3
Foundation & Framing
Pilings driven to refusal and treated framing at the joist spacing composite spans require.
- 4
Composite Installation
MoistureShield boards installed with the specified fastener systems, gapping, and edge details for a clean permanent surface.
Why MoistureShield Composite
MoistureShield is rated for ground, underground, and underwater contact — unique among mainstream composites and exactly what dock surfaces, steps, and swim platforms demand. The substructure is marine-grade treated timber (2.5 CCA saltwater, .60 freshwater) so the whole assembly ages together.
The Composite Dock Truth: The Board Rating Is Everything
Composite decking earned its reputation on backyard decks — dry, elevated, above-ground service. A dock is none of those things. Boards get splashed daily, run to the waterline at steps and swim platforms, and live over water permanently. Most composite brands are explicitly warranted for above-ground use only, which makes their installation on a dock a warranty-voiding bet. This is why we standardized on MoistureShield: solid-core boards engineered and warranted for ground, underground, and underwater contact — the only rating that actually describes a dock's life.
With 40+ years of construction experience, we've watched materials come and go, and our brand loyalty is earned, not sponsored: MoistureShield's encapsulated core doesn't wick water at cut ends, doesn't swell and delaminate at splash zones, and holds color under the doubled UV load of direct sun plus reflection off the water. The Vision series adds deeper woodgrain realism and enhanced fade resistance for owners who want the premium look.
A composite dock is only as good as its frame. We build the substructure the way we build everything: pilings driven to refusal, environment-treated framing at the tighter joist spacing composite spans require, and stainless or hot-dip galvanized fastener systems per MoistureShield's specification. The 40-year board deserves a 40-year frame.
What Composite Ownership Actually Feels Like
The maintenance delta is the daily reality: no sealing, no staining, no graying, no splinters — rinse it when the pollen falls and you're done. For owners who've kept timber docks, the disappearing chore list is the whole argument; for HOAs and rental properties, it's a budget line deleted. Texture matters on the water too: composite's molded grain keeps wet traction where smooth-worn timber turns slick with algae.
The honest trade-offs: composite costs more per foot than treated timber, runs warmer than wood in direct summer sun (lighter colors mitigate it meaningfully — we steer waterfront clients there), and repairs mean matching a manufactured product rather than grabbing a board from the yard. On docks you'll keep for decades, the total-cost math typically lands in composite's favor; on short-horizon properties, timber may pencil better. We quote both and let the numbers argue.
Composite conversion doesn't require new construction: if your existing frame is sound, our dock re-decking service swaps tired timber for MoistureShield at a fraction of rebuild cost. New builds, meanwhile, are designed composite-first — spacing, fasteners, and details per spec from the first joist.

Composite Dock Construction FAQs
Is a composite dock worth the extra cost?
On a dock you plan to keep, usually yes — the eliminated sealing cycle and board replacement compound over decades. We quote timber and composite side by side so the math is yours to judge.
Why MoistureShield and not Trex or TimberTech?
Water contact. MoistureShield is engineered and warranted for it; most competitors are above-ground-only products. On a dock, that distinction is the whole game.
How long does a composite dock last?
MoistureShield carries multi-decade warranties, and the boards genuinely outlast their warranty terms in service — no rot, no borer damage, no UV breakdown of the surface. The practical lifespan question shifts to the frame, which is why we build the substructure to the same standard.
Does composite decking sag between joists?
Not when framed to spec — composite requires tighter joist spacing than timber, and we frame for it. Sag complaints trace to composite installed over frames spaced for wood, a corner we don't cut.
Can I mix composite decking with a wood frame?
That's the standard assembly: treated structural timber frame (2.5 CCA salt, .60 fresh), composite surface. The frame is protected from sun by the deck above it and engineered for the moisture below it — each material where it excels.
Is composite slippery for swimmers climbing out?
MoistureShield's textured surface grips well wet — typically better than algae-slicked smooth timber. At ladders and swim platforms, board orientation and texture give bare feet reliable purchase.
