Common questions
Why do waterfront structures need reinforcing over time?
Constant exposure to tides, wash and weather gradually weakens retaining walls, ramps and similar structures, and reinforcing them before damage becomes severe helps avoid a full rebuild later.
What causes erosion around marine infrastructure sites?
Wave action, tidal movement and poor drainage all wear away banks and foundations over time, and left unmanaged, this erosion can undermine nearby structures and access points.
How does tidal movement affect infrastructure work near the water?
Work areas can flood or become inaccessible for parts of the day depending on the tide, so we plan projects around these windows to keep the site safe and workable.
