As part of its Masterplan 2040 project, which will see a significant volume of renovation and expansion work take place over the next two decades, Dublin Port Company (DPC) identified the need to create a new loading yard and terminal at Dublin Port.
Effective surface water management is essential for the smooth running of a port as excess surface water can represent a significant health and safety hazard. A robust, reliable and sealed drainage solution was required that would stand up to the rigours of modern cargo handling, while protecting the environment and preventing the contamination of natural water resources.
Given the sheer size and weight of both the cranes and commercial vehicles used for the loading and unloading of cargo, a number of the existing surface water management channels throughout the port had begun to show signs of fatigue under the intense loading demand placed on gratings.
Eoghan Liston, Business Development Manager, ACO Ireland said: “Existing channels installed throughout the port were failing to cope with the point-loading demands placed on the gratings. In particular, problems were arising when the wheels of cranes were turning 90 to 180° on the gratings themselves, as this placed a huge amount of pressure on the material and DPC was keen to avoid any future channel draining quality issues.”
ACO Ireland, a division of ACO Water Management UK provided a full monocast solution for the project using ACO RoadDrain. This is manufactured from Vienite®, ACO’s high strength recycled polymer concrete.
Manufactured to Load Class F 900 – the highest classification available – the RoadDrain range is not only strong enough to handle the extreme point-loading demands posed by day-to-day activity at the port, but offers a high intake area thanks to 15mm slots to deliver maximum hydraulic performance. ACO RoadDrain is also easily accessible for maintenance.
An on-site ‘wet test’ was set up to show that the completed system could meet the mandated levels of water tightness. ACO RoadDrain has a dedicated sealant groove which was sealed with products from the company Sika Bond.
ACO’s National Technical Consultant Keith Oldham was integral to this process and oversaw all on-site testing with the contractors. Sika Bond was quickly able to provide the necessary bonding and sealing materials – which are mandatory under Ireland’s comprehensive Environmental Protection Agency (EPA) regulations. The mock installation was then set up at the port and left to cure for 24 hours, before ACO undertook a full wet test with representatives from Dublin Port, the consultant engineers and contractors all on site, to review the outcome.
Dublin Port then placed a significant order of RoadDrain channel to be used for the project.
“Not only was the client very pleased with the quality of the product, but also the support from the ACO team. The product management and design services have been imperative, as has the support in defining the application challenges and supplying in-depth hydraulic analysis.” Eoghan Liston, Business Development Manager, ACO Ireland.
