Marley supplied softwood decking for a striking and complex decked pontoon at Heron Quays in Canary Wharf. This pontoon had three key specification challenges: slip resistance, durability and aesthetics.
The finished project needed to have a high aesthetic appeal as the pontoon was visible from the high buildings surrounding the site. A finish similar to the look of a hardwood was required, but at a lower cost. As the deck was for a pontoon in the Thames, durability and resistance to salt water was important, as was the need for elevated performance in a high slip risk area.
Marley Antislip Plus® timber decking was selected. This range has been designed to replicate the look of a hardwood. It is often chosen for its visual appeal, finished with a brown stain to achieve a soft brown natural look.
The product is pressure-treated with preservatives to the relevant use class. It resists weathering longer than other decking but will eventually, as with all timber decking, turn to a soft silver grey.
Antislip Plus® decking is manufactured from slow-grown Northern European softwood. The deck boards were treated to ‘Use Class 4’ to cope with the demands of the challenging salt water location.
Anti-Slip® inserts were used to give a superior non-slip finish exceeding the HSE requirements for ‘extremely low slip risk’ requirement for BS7976.
There were also technical challenges in the installation. Specialist contactor Chestnut Products Ltd was presented with a report on the varying level of the concrete substrate from which the deck frame would be installed. To ensure the finished deck was perfectly level, a laser level was used for the duration of the project, while the different frame sections were cut and shimmed for a perfect finish.
Also, the pontoon edge required a pedestrian guardrail that required complex cutting and fixing. An eye-catching finish was created by installing the deck boards with directional changes on the diagonals, which also added to the intricacy of the installation.
Mark Tyrrell of Chestnut says “We’re really proud of this job; it took 8 men 4 weeks as it was such a complex job. We used 22,200 screws and installed 4564 linear metres of deck boards on the pontoon which ended up perfectly level.”
Chris Wellbelove from Blakedown Landscapes also comments: “We chose Marley Eternit timber decking for the quality. It’s a trusted, durable product that could meet the projects requirements. Chestnut Products we had used before and we were confident they would deliver the project to the highest standard.”
