Elevated Pile-Grid System™

(Deep-Foundation Grid for Coastal, Hurricane & Flood-Prone Regions)

The Elevated Pile-Grid System™ is WAN-NSO’s premier deep-foundation solution engineered specifically for sites exposed to storm surges, high winds, saltwater corrosion, and unstable coastal or marine soils.
It elevates modular structures above hazard levels while maintaining long-term structural stability in extreme climates.

This system is deployed across coastal zones, hurricane corridors, river basins, marine sites, and regions facing significant soil erosion or flood risk.

TECHNICAL STRENGTHS

1. Marine-grade Steel Piles with Nano-Ceramic Coating

Traditional galvanized steel corrodes rapidly in coastal regions. WAN-NSO’s nano-ceramic coating offers:

Structural Protection Benefits
  • chemical resistance to saltwater
  • zero-to-minimal oxidation in high-humidity zones
  • improved abrasion resistance from sand & salt spray
  • durability comparable to marine & offshore oil platform standards
Expected Lifespan

70–100 years, depending on tidal exposure and maintenance schedules.

2. Deep Anchoring Profiles (15–25 ft)

Depth varies depending on:

  • soil density (sand, sediment, clay, rock)
  • tidal motion
  • storm surge potential
  • expected wind uplift loads
  • seismic activity
Engineering Benefits
  • prevents sinking/tilting during floods
  • resists overturning in hurricane winds
  • remains stable even if surface soil washes away
  • mitigates liquefaction in seismic zones

The piles act as vertical anchors, ensuring the structure remains fixed under extreme environmental loads.

3. Hurricane Tie-Down System (Rated for 175 mph Winds)

This is WAN-NSO’s high-performance anti-uplift assembly, including:

  • post-tensioned steel rods
  • high-strength anchor plates
  • reinforced bearing nodes
  • distributed load brackets
Performance Characteristics
  • counters negative pressure during hurricanes
  • keeps modules locked to the grid frame
  • prevents lateral movement during storm gusts
  • reduces risk of twisting or shifting during impact events

Designed to comply with:

  • FEMA guidelines
  • ASCE 7 wind-load standards
  • ICC coastal construction codes

4. Diagonal Cross-Bracing (X or K Configuration)

Bracing prevents catastrophic failure during sideways loading events.

What it Protects Against
  • storm-induced oscillation
  • lateral shear forces from waves or wind
  • vibration from coastal winds
  • structural racking in stacked modular units
Engineering Effect

Cross-bracing transforms the pile grid into a rigid, unified structural frame, dramatically boosting lateral stability.
