Ecocoast was awarded a contract to refurbish over 70 marine piles at Al Hamra Marina in Ras Al Khaimah, the UAE. Management decided to do a marina-wide renovation, including pile refurbishment, after taking it back from the operator.

The marine piles were towards the end of their lifespan – extremely rusted – because of the wave conditions in the marina. Rather than replacing all piles, management at Al Hamra Real Estate Development decided to extend the lifespan of the piles by contracting Ecocoast to install UHMW-PE sleeves, a more innovative and sustainable option.

The works involved pile cleaning, blasting and coating, including supply and installation of UHMW-PE pile sleeves, pile top covers and GRP pile caps.


Marine pile refurbishment offers unique challenges, as piles are exposed to water, dry-wet cycles that follow tides. It was important not to damage any vessels while sandblasting and working on the lower parts of the piles at low tide. Complex logistics were involved to manage traffic inside the marina.

Not causing any pollution was another key factor for the client, both water and noise pollution. When using marine pile sleeves that prolong the lifespan of piles, the focus goes to seeking ways to repair and protect rather than replace, being a much more sustainable solution. The marine piles were also vacuum blasted in order to minimize disruption to the surroundings. Vacuum blasting is not only eco-friendly, but also provides a lower noise level than standard blasting.


Ecocoast has successfully installed the pile sleeves to help restore the marina back to its world class status. The sleeves offer a nice aesthetic appearance, giving the piles a high gloss surface. The project was conducted with the lowest environmental impact and noise pollution possible, as per the client’s request.
