ECCLES SECURES AQUADECK™ PROJECT FOR M25/A10 JUNCTION UPGRADE
Eccles provides advanced bridge drainage solutions with over 1,000 AQUADECK™ units installed across nine key locations, supporting critical infrastructure improvements at one of Hertfordshire’s busiest junctions.
Contractors – Grahams
Project – M25 JUNCTION 25
Consultants – Sweco
Product Supplied – Full AQUADECK™ system

The construction works, which began in 2021, included an upgrade of the intersection of the M25 and A10 at Cheshunt to increase traffic capacity.
The project involves widening the 25 roundabout to four lanes, widening the M25 eastbound diverge and providing a segregated left turn for A10 northbound traffic, widening the westbound M25 diverge, and widening the A10 southbound entry to the roundabout.
Up to 6,300 vehicles per hour usually travel through the junction 25 roundabout at peak times, causing congestion and regular delays. The A10 southbound approach into the junction is also a congestion hotspot in Broxbourne, Hertfordshire.
During 2024, Eccles secured the order from Grahams to provide AQUADECK™ Bridge Drainage units to 9 locations across several structures.
Chris Rothery AQUADECK™ Project Director, commented, “We undertook hydraulic design work for Grahams to ensure we proposed the most cost-effective solution for them”
A total of over 1000 AQUADECK™ 350mm wide units were installed, including Expansion Joint fabrications for each structure
