COASTAL CANAL BULKHEAD & SEAWALL MARINE INSPECTIONS.
Protecting waterfront assets across Galveston Bay and coastal canal communities. We evaluate tie-back rod tension, deadman anchor displacement, sheet piling rotation, weep hole filter cloth, and boat lift motors.
Meet Inspector Mack & The Secured Team
Every inspection is led directly by TREC Professional Master Inspectors using calibrated diagnostic gear. We don't just check cosmetic boxes—we map subgrade foundation movement, scan thermal anomalies through solid sheetrock, and scope subterranean lateral lines to defend your earnest money and equity.

Canal Marine Forensics: Tie-Backs, Deadmen & Rotting Whalers
Inspector Mack explores the engineering behind coastal bulkheads and how waterfront buyers avoid $30,000 seawall rebuilds.
"If you see a depression or sinkhole in the grass 10 feet behind a canal bulkhead, that's not settling soil—that means your geotextile filter fabric has torn and your lawn is washing into the canal with every tide."
WHAT WE SPECIFICALLY AUDIT & DELIVER
Our forensic checklist exceeds standard minimum requirements. Every component is rigorously evaluated and cataloged with high-resolution imagery and severity tiers:
Vinyl, Composite & Wood Sheet Pilings
Evaluating sheet piling interlocks, cracking, UV degradation, toe depth penetration, and marine wood borer damage.
Tie-Back Rods & Deadman Concrete Anchors
Checking galvanized tie-back tension nuts, washers, rod corrosion, and soil sinkholes above buried deadman anchors.
Marine Timber Whalers & Top Cap Beams
Inspecting upper and lower pressure-treated whalers, through-bolts, cap boards, and wood decay fungus.
Weep Holes & Geotextile Filter Fabric
Checking weep hole diameter, elevation above normal high tide, and geotextile cloth to ensure hydrostatic pressure release.
Backfill Soil Compaction & Scour Holes
Probing lawn backfill behind the wall for subsurface soil washouts, voids, and canal bottom scour trenches.
Boat Lift Pilings, Cradle Motors & Cables
Auditing treated timber guide pilings, stainless/galvanized lift cables, grooved winding drums, drive belts, and electric motors.
Marine Dock Electrical & GFCI Protection
Testing marine sub-panels, outdoor receptacle GFCI protection, dock lighting, and saltwater corrosion at switches.
Finger Piers, Cleats & Mooring Hardware
Checking wood/composite dock framing, stringer bolts, rub rails, mooring cleats, and boarding ladder attachments.
Texas Gulf Coast Environmental Defect Matrix
Southeast Texas structures face unique environmental stressors that generic national inspection checklists routinely overlook. We specialize in identifying these regional failure modes:
Snapped Galvanized Tie-Back Rods
Corrosion in damp saline soils rusts 3/4-inch steel tie-back rods completely through behind the timber whalers.
Torn Geotextile Fabric Behind Weep Holes
Deteriorated filter cloth allows tidal ebb and flow to vacuum soil from behind the bulkhead into the canal.
Frayed Boat Lift Stainless Hoist Cables
Salt buildup and friction cause individual wire strands (bird-caging) to snap on boat lift winding drums.
Advanced Diagnostic Equipment Suite
Human eyes alone miss hidden electrical hotspots, subterranean pipe collapses, and millimeter-level slab deflections. Every Secured Inspections vehicle is equipped with industrial instrumentation:
5-Foot Stainless Soil Sounding Probe
Detects hidden soil washouts and voids behind the bulkhead sheeting that indicate failing filter cloth.
Precision Laser Alignment Level
Measures horizontal bowing and outward tilt angle along the entire seawall capline.
Waterproof Underwater Endoscopic Camera
Submersible camera inspecting underwater toe depth, lower whalers, and submerged mudline scour.
Marine Circuit & GFCI Tester
Verifies trip calibration on dock sub-panels and boat lift motors in wet marine environments.
Actual Field Finding & Financial Impact
Here is an authentic defect documented in our recent inspections, demonstrating how our forensic reports deliver tangible financial leverage:
3 Snapped Tie-Back Rods & 3-Inch Outward Bulkhead Rotation
Our laser alignment survey revealed a 3.2-inch outward bulge in the center of the 80-foot vinyl bulkhead. Subsurface probing identified two 3-foot-deep sinkholes behind the cap where galvanized tie-back rods had rusted through completely.
Frequently Asked Questions: Bulkhead & Seawall Inspection
Everything you need to know about this inspection scope, scheduling timeline, and Texas legal protections:
Q1What is a bulkhead inspection and why is it essential?▼
A bulkhead (or seawall) is the retaining wall holding your lawn and foundation out of the canal or bay. In coastal Texas, bulkheads endure constant salt-water immersion, boat wakes, and hurricane storm surges. If a bulkhead fails, your yard washes away and your home's foundation is compromised.
Q2How long does a vinyl or wood bulkhead typically last?▼
A quality vinyl sheet-piling bulkhead typically lasts 30 to 50 years, but the galvanized tie-back rods and treated wood whalers holding it usually require maintenance or replacement every 15 to 20 years due to coastal soil corrosion.
Q3Do you inspect boat lifts as part of the marine audit?▼
Yes! We test the boat lift electric motors, drive pulleys, stainless steel hoist cables, winding drums, guide pilings, and GFCI electrical safety disconnects.
Q4What does it mean if there is a sinkhole in the yard near the bulkhead?▼
A sinkhole indicates that the geotextile filter fabric behind the weep holes has torn or separated. With every tidal cycle, water pulls dirt through the weep holes into the canal, creating an empty cavity beneath your lawn that will eventually collapse.
Q5How do you check for outward wall movement?▼
We shoot a precision laser alignment line along the top cap of the bulkhead to measure horizontal deflection (bowing) and use digital inclinometers to measure the vertical angle of rotation.
Q6Can I bundle a bulkhead inspection with my waterfront home purchase?▼
Yes! We provide complete waterfront inspection packages combining your home inspection, WDI termite audit, and marine bulkhead/boat lift evaluation into a single visit.
