At a glance
A waterfront installation combines several exposures. Water uptake, wet grip, fastening durability and the supporting structure must be assessed together.
Key points
- Exposure: Splash, pooling or immersion.
- Assembly: Fixings, supports and drainage.
- Operation: Wet grip and maintenance access.
The technical principle #
Intermittent splash, standing water and permanent immersion are different service conditions. Wetting can affect mass, dimensions and material response, while retained water can interact with freezing. A laboratory immersion result does not automatically approve every marine use or describe the complete installed assembly.
What to specify and verify #
Define the location of boards relative to water, expected access, maintenance and any exceptional loads. Obtain relevant product evidence and a suitable fixing specification for the exposure. Consider safe cleaning access, replaceable components and how water escapes around joints and supports.
Application and common mistakes #
Do not describe a board as universally marine-grade without a defined scope. Green Plank's published Nordic coastal references are useful starting points for project questions, not blanket approvals. Ask for the exact product, installation date, maintenance record and current condition of a comparable site.
Discuss your project with Green Plank #

Common questions
Does a coastal reference approve permanent immersion?
No. The reference conditions and the proposed application must be compared explicitly.
