Has a Clyde flood knocked your jetty about, or have the piles just gone soft and the decking let go? We replace piles, re-deck, rebuild bracing and refloat pontoons that ride low, from Batemans Bay upriver to Nelligen. Say what has happened and where on the river the jetty sits.

This estuarine environment is particularly aggressive on timber structures — the mixing of fresh and salt water creates ideal conditions for both marine borers in the lower zone and fungal rot in the splash zone above.
Upstream from the bridge at Nelligen, the river narrows and current increases, scouring around pile bases during flood events. Downstream around Catalina and the town wharf precinct, tidal flow and boat wash are the primary stressors. Surf Beach, Malua Bay and Long Beach properties face open ocean exposure with salt spray accelerating above-water timber degradation.
Repair work around Batemans Bay needs to account for these varied conditions — heavier pile embedment in the scour-prone upper river, borer-resistant species in the tidal zone, and UV-stabilised coatings for ocean-exposed decking.
Replace borer-damaged or flood-undermined piles with H6-treated hardwood rated for the Clyde River's estuarine conditions. Cost per pile depends on length, timber species and how deep it needs to be driven.
Re-deck with durable hardwood, replace corroded fixings with 316 stainless and rebuild cross-bracing compromised by flood debris or age.
Re-float sinking pontoons, replace failed floatation modules and service mooring pile connections. Essential maintenance for Clyde River berths.
Full structural survey with pile sounding, scour assessment and decking condition report. Includes photo documentation and prioritised repair plan. Cost depends on structure size and access.
The Clyde River is prone to significant flood events that scour pile bases and deposit debris against jetty structures. After a flood, send us the details.
The NSW Government classes the Clyde as a barrier river with an open entrance. Its estuary covers 17.5 square kilometres but drains a catchment of 1,722.9 square kilometres, so floodwater from the whole catchment passes through it on the way out to Batemans Bay. For erosion-prone banks upstream of Nelligen, the Batemans Bay and Clyde River Estuary Processes Study, quoted in NSW Maritime's 2009 Clyde Estuary Safe Boating Plan, says floods and natural meander are far more significant causes of bank erosion than boat wash. On the upper river, the bank at the landing and the bed around the piles are worth checking along with the timber.
The tidal range does not shrink on the way up to Nelligen. Manly Hydraulics Laboratory's April 2023 tidal planes analysis gives a mean tidal range of 0.915 m at Princess Jetty in Batemans Bay and 1.024 m at Nelligen. That puts close to a metre of pile in and out of the water with each tide, and work at the waterline has to be timed around it.
What surrounds the jetty matters as well. NSW DPIRD's mapping puts the tidal Clyde inside Batemans Marine Park, mostly in the Batemans Bay Habitat Protection Zone, with sanctuary zones at Pelican Inlet, Waterfall Creek and the Buckenbowra River. Its estuarine mapping shows Zostera seagrass and extensive mangrove in the estuary but no Posidonia australis, which is mapped only in the bay itself. If your jetty is near a sanctuary zone, seagrass or mangroves, say so when you enquire.
Enquiries are welcome from jetty and pontoon owners on the tidal Clyde River from Batemans Bay upriver to Nelligen, and from around the bay and the Eurobodalla coast at Catalina, Sunshine Bay, Long Beach, Surf Beach, Malua Bay, Lilli Pilli, Broulee, Mossy Point and Tomakin. Say where your jetty is and whether it can be reached from land or only by water.
