Common questions
What materials are used to build pontoons and jetties?
Timber, steel and composite decking are all common choices, often used together across one structure, with the right combination depending on exposure to saltwater, expected loads and how the structure will be used.
Why is groundwork important before building a marine structure?
Soft or uneven ground along the foreshore can undermine a structure if we do not prepare it properly first, and compaction and stable foundations help the finished build handle tides and everyday use.
How does tidal movement affect the construction of a new structure?
Work areas can flood or become inaccessible at different points in the tide cycle, so we stage construction around these windows to keep the build progressing safely.
