Dock & Pier Builders in Greater Houston & Lake Conroe

Why a Professionally Engineered Dock Outlasts a Handyman Build

The difference between a dock that lasts thirty years and one that racks, sags, or loses pilings in a decade is almost never the decking you can see — it is the foundation and framing you cannot. Piles that are pushed or jetted instead of driven to refusal work loose as lake levels cycle. Framing sized for a backyard deck flexes under wave and boat-impact loads it was never designed for. Fasteners rated for dry land corrode at the waterline within a few seasons. We engineer every dock for its actual site: water depth, bottom composition, seasonal level swing, prevailing wind fetch, and the boat traffic it will absorb.

Because Jordan Marine Construction runs its own barge-mounted and land-based pile-driving equipment, we control the single most important variable in dock construction — pile embedment — rather than subcontracting it out. Every piling is driven to refusal, verified for alignment, and only then framed. That is also why we can stand behind structures on high-traffic water like Lake Conroe, where weekend chop and wake loads punish under-built docks.

Materials matter just as much in Texas waters. Freshwater lakes like Conroe and Livingston call for .60 CCA-treated timber; brackish and saltwater exposure on Galveston Bay and the Gulf Coast requires 2.5 CCA treatment to resist marine borers that will eat unprotected wood from the inside out. Using the wrong retention level is one of the most common — and most expensive — mistakes we see in docks built by non-marine contractors.

Dock Types We Build: Fixed-Pile, Floating, and Hybrid Systems

Fixed-pile docks are the workhorse of Texas lakes: pilings driven to refusal, treated structural framing, and radius-edge decking that stays put through storms and level swings. They are the right call for stable-depth shorelines, boat houses, lifts, and any structure that needs to carry real load. Most of our Lake Conroe and Lake Livingston work is fixed-pile.

Floating docks ride on encapsulated flotation and adapt automatically to water-level changes, which makes them well suited to reservoirs with large drawdowns, deep water where piles are impractical, or marina-style layouts. We also build hybrids — a fixed pier to a floating section — that give you stable shore access plus a low-freeboard swim and board platform at the water.

Beyond the platform itself, we integrate the full waterfront system in one build: boat lifts and PWC lifts, covered slips and boat houses, swim ladders, benches, fish-cleaning stations, lighting, and dock-to-bulkhead transitions. Designing these together — rather than bolting them on later — is what keeps load paths correct and the finished structure looking like one piece instead of an accumulation of add-ons.

Permitting a Dock in Greater Houston: SJRA, City of Houston, TRA & USACE

Every major waterbody in our region has a controlling authority, and building without the right permit can mean stop-work orders, fines, or forced removal. On Lake Conroe, docks and other over-water structures are permitted through the San Jacinto River Authority (SJRA), which reviews setbacks, dimensions, and encroachment onto the lake. On Lake Houston, the City of Houston governs pier permits. Lake Livingston structures go through the Trinity River Authority (TRA), and coastal work on Galveston Bay and the Gulf involves the U.S. Army Corps of Engineers Galveston District and the Texas General Land Office.

We handle this process for our clients start to finish — drawings, applications, and coordination with the authority — because we do it every month and know what each reviewer expects to see. It is one of the practical advantages of hiring a marine contractor who builds on these specific waters rather than a general contractor learning the process on your project.

Built for Texas Conditions: Heat, Hurricanes, and Fluctuating Lakes

Gulf Coast weather is the ultimate stress test for waterfront structures. Hurricane and tropical-storm events push surge, debris, and sustained wave action against everything at the waterline; the 100-degree Texas summer cycles decking through brutal expansion and UV exposure; and reservoir levels rise and fall with drought and flood-control releases. We design for all of it — pile embedment sized for storm loads, hot-dip galvanized and stainless hardware, framing connections that resist uplift, and deck heights set with real water-level history in mind.

That local knowledge shows up in small decisions that pay off for decades: how high to set a deck on a Conroe cove that sees two-foot seasonal swings, when a floating section makes more sense than fixed framing, how to orient a slip so the prevailing southeast wind doesn't work a moored boat against the structure. It is the kind of judgment that only comes from building — and repairing — hundreds of structures on the same waters.

Engineering Best Practices That Actually Make a Dock Last

A dock is only as good as the pilings you can't see and the hardware holding it together. The single biggest predictor of a dock's lifespan is pile embedment — which is why we drive every piling to refusal with a barge- or land-mounted hammer rather than jetting or pushing it to an arbitrary depth. On Lake Houston the City's building code sets a floor for this (private-pier piles at least 4 inches in diameter, embedded a minimum of 30 inches into firm soil), but firm-soil refusal on a wind-fetch cove often calls for far deeper embedment than the minimum, and that judgment is where engineering earns its keep.

Hardware is the second thing that separates a thirty-year dock from a ten-year one. We through-bolt structural connections with hot-dip galvanized bolts, washers, and nuts — and specify stainless where brackish water demands it — instead of relying on nails or coated screws that bleed rust within a few seasons. Framing is sized and braced for real loads: Houston's code calls for a minimum 50 psf live floor load on private piers and 100 psf on commercial, with diagonal 2×4 pressure-treated X-bracing on the bents, and we build to those numbers or better with hurricane-rated connections that resist uplift.

Materials are matched to the water, not to whatever is on the truck. Freshwater lakes like Conroe and Livingston call for .60 CCA-treated structural timber; brackish and saltwater exposure on Galveston Bay requires 2.5 CCA to resist the marine borers that hollow out unprotected wood from the inside. Decking can be treated southern yellow pine or a composite like MoistureShield for a splinter-free, low-maintenance sun deck — but the framing underneath is always environment-correct treated timber. Getting the retention level wrong is one of the most expensive mistakes we see on docks built by non-marine contractors.

Dock Power, Lighting, and Shock Safety: Built to NEC Article 555

Electricity and water are the most dangerous combination on any dock, and wiring is the detail budget builders skip. Electric shock drowning (ESD) — where stray current in the water paralyzes a swimmer — is a real and preventable hazard, and the National Electrical Code addresses it directly in Article 555, which governs marinas, boatyards, and docking facilities. Dock receptacles must be GFCI-protected, metal parts bonded, and equipment grounding carried correctly so a fault trips the breaker instead of energizing the water.

When we build a dock with lighting, receptacles, a boat lift, or shore power, that wiring is installed to NEC Article 555 practice: ground-fault protection, proper bonding and grounding, weather- and corrosion-rated fittings, and clear labeling. It is not an upsell — it is the difference between a dock that is safe to swim near and one that is a hidden liability. If your existing dock has ungrounded outlets or a lift wired without GFCI protection, that is worth correcting before anyone is in the water around it.

Lighting is both a safety and a livability feature. Piling-cap, deck-perimeter, and step lighting keep the structure visible and usable after dark, and the City of Houston code even requires amber warning reflectors on Lake Houston piers — 3-inch minimum lenses, no more than 8 feet apart, set 18 inches above spillway elevation — so the dock is visible to boaters at night. We integrate the electrical, lighting, and reflector requirements into the build instead of bolting them on afterward.
