GUIDE
Why marine construction specialists are building better patios — and how the method works.
For over 17 years, Waterfront Unlimited has built elevated docks, boathouses, and waterfront platforms on the Guadalupe River lake system. Every one of those structures uses the same construction method: steel pipe pilings driven into the ground, structural steel beams welded across the pilings, and reinforced concrete poured on top.
These structures survive river floods. They handle decades of wave action, UV exposure, freeze-thaw cycles, and constant moisture. They don’t rot, warp, fade, or burn. They last.
The realization behind Wulfhe Outdoor Living was straightforward: if this construction method can survive on water, it performs even better on dry land. Inland properties don’t have wave action, fluctuating water levels, or marine corrosion. A dock-grade structure built on solid ground will outlast virtually anything else in residential construction.
That’s what we now offer to Hill Country homeowners — the same steel, the same concrete, the same crew, the same construction standards. The only difference is the address.
Every elevated concrete deck we build follows the same sequence used for waterfront docks. Here’s the process, step by step.
5.5-inch steel pipe pilings are set into the ground at the spacing required by the project. On a waterfront dock, these pilings go into the lake bed or riverbank. On your property, they go into soil or rock. The method is identical.
Pilings can be set at different depths depending on terrain. This is what makes the system ideal for hillside and sloped lots — each piling reaches whatever depth it needs to reach, and the platform above comes out level regardless of what the ground looks like underneath.
Once the pilings are set, structural steel beams (C-channel steel in 3-inch, 4-inch, and 12-inch sizes) are welded to the pilings. This creates the skeleton of the deck — the framework that will support the concrete slab above.
The steel framework determines the shape, size, and elevation of the finished deck. Multi-level designs, L-shaped layouts, and wraparound configurations are all possible because the framework is custom-fabricated for each project.
Reinforcing steel (rebar) is placed across the framework in a grid pattern. Concrete is then poured over the rebar and steel framework and finished to the homeowner’s chosen surface treatment.
The concrete slab cures into a monolithic surface — a single, continuous platform with no seams, no boards, no gaps, and no joints to collect debris. It’s a fundamentally different product than a deck made of individual boards fastened to a frame.
The concrete surface can be finished in multiple ways: stamped patterns that mimic stone or tile, acid stain for rich color variation, exposed aggregate for a textured natural look, smooth trowel for a modern finish, or standard broom finish for maximum traction.
Steel or cable railings are installed as needed. Integrated LED lighting (surface-mount or under-rail), built-in planters, seating walls, and ADA-compliant ramp access can all be incorporated into the structure.
The comparison between a dock-grade concrete deck and traditional decking materials isn’t close. Here’s why.
A pressure-treated wood deck in the Texas Hill Country lasts 10–15 years before it needs major repair or replacement. Composite decking (Trex, TimberTech, Fiberon) lasts 20–25 years under ideal conditions. A steel-and-concrete deck lasts 30–50 years with zero maintenance. The concrete doesn’t rot, the steel doesn’t warp, and the pilings don’t shift.
This is not a minor consideration in the Hill Country. Wood decks are combustible. Composite decking melts and can ignite. Steel and concrete are completely non-combustible — they cannot catch fire from embers, radiant heat, or direct flame contact. During wildfire events, your deck material is either fuel or it isn’t. Concrete isn’t.
Wood decks require annual staining or sealing, periodic board replacement, and ongoing inspection for rot, termite damage, and structural deterioration. Composite decks need less maintenance but still require cleaning and can experience mold growth, fading, and thermal expansion issues. Concrete decks require none of this. No staining. No sealing. No board replacement. No rot. No termites. Nothing.
A concrete slab on steel pilings can support virtually any load. Hot tubs, outdoor kitchens with stone countertops, large gatherings — the structure doesn’t care. Wood and composite decks have load limits determined by joist spacing and fastener capacity. Concrete doesn’t have this constraint.
Steel pipe pilings can be set into any terrain — flat, sloped, rocky, or uneven. Pilings go to different depths as needed, and the platform above comes out level. This makes the system ideal for Hill Country properties where slopes, limestone outcroppings, and significant grade changes are the norm rather than the exception.
Elevated concrete decks start at $60 per square foot installed in the Texas Hill Country. For comparison, mid-range composite decking from Trex or TimberTech runs $50–$75 per square foot installed in the same area. Wood decking runs $25–$45 per square foot but requires $8,000–$15,000 in maintenance over 20 years.
The upfront cost of a concrete deck is comparable to composite. The 20-year total cost of ownership is significantly lower because maintenance cost is zero. For a homeowner planning to stay in their property long-term, it’s the most cost-effective option available.

Dock-grade concrete decks are not for everyone. They’re for property owners who:
We want to be clear about what we don’t do. We are not a flatwork concrete company. We don’t pour driveways, sidewalks, or slabs on grade. We are not a general contractor. We don’t build fences, pergolas, or patio covers.
We do two things: elevated concrete decks on steel pipe pilings, and gravity-stacked limestone retaining walls. Both are built using marine construction methods proven over 17 years on the Guadalupe River. That specialization is what makes the quality possible.
