South Curl Curl Boardwalk

DM Composites was commissioned to deliver a 50-metre by 3-metre elevated FRP boardwalk along Sydney’s coastline, providing a durable, corrosion-resistant structure with integrated AS-compliant handrails, secure sandstone anchoring, and seamless connection to existing coastal pathways and landscaping.

LOCATION

Menangle Street in Picton has long served as a vital corridor linking residential neighbourhoods with the town centre, schools, and community facilities. Once fragmented by narrow, non-compliant footpaths, the route posed challenges for pedestrians and cyclists alike. As part of the WestInvest community infrastructure program, Wollondilly Shire Council prioritised this stretch for a major upgrade—transforming it into a modern, continuous shared path that improves safety, encourages active transport, and reduces reliance on vehicles.

OUTCOME

DM Composites was engaged to design, supply, and construct a 50-m-long and 3-m-wide elevated FRP boardwalk system. A modern, corrosion-proof structure tailored to withstand the harsh marine exposure of Sydney’s coastline.

CONSTRUCTION CHALLENGES AND SOLUTIONS:

Cliffside Access & Limited Working Area:

With the boardwalk constructed directly above the rock escarpment adjacent to the ocean pool, site access was restricted. Materials and machinery were carefully sequenced to prevent encroachment on the beach below or vegetation above. Lightweight FRP sections allowed for manual handling and smaller lifting equipment compared to steel alternatives. 

Harsh Marine Conditions:

The coastal site experiences constant salt spray and high UV exposure. All FRP elements were designed with fully impregnated pigmentation and resin systems tested for coastal applications, ensuring zero corrosion and colour stability over decades. 

Structural Integration:

DM Composites engineered precision transitions between the concrete approach slabs and the FRP superstructure, maintaining smooth accessibility and continuity in the boardwalk system.
