Important Notes

  • • Calculations are estimates and should be verified by a structural engineer
  • • Consider wave action, wind loads, and ice conditions in your area
  • • Flotation should be distributed evenly under the dock
  • • Regular inspection and maintenance of flotation is recommended

About Dock Flotation

EPS vs STYROFOAM™

While often confused, EPS (Expanded Polystyrene) and STYROFOAM™ are different materials with varying densities and buoyancy characteristics.

  • EPS: Lower density, higher buoyancy, more cost-effective
  • STYROFOAM™: Higher density, better structural properties, more durable

Design Considerations

  • • Account for seasonal water level changes
  • • Consider the weight of attached structures (ramps, railings)
  • • Plan for future additions or modifications
  • • Ensure proper attachment methods for flotation
