M1 Elstree Road Bridge Abutment Repairs
The Project
| Shotcrete Services Ltd were appointed to deliver specialist concrete repairs to the bridge abutments supporting a section of the M1 motorway spanning Elstree Road in Bushey, Hertfordshire.
The scheme formed part of an essential structural maintenance programme designed to extend the operational life of the bridge infrastructure while minimising disruption to one of the region’s busiest transport corridors. Works were completed in carefully planned phases to ensure the structural integrity of the bridge was maintained throughout the programme. The project involved hydro-demolition, concrete breakout, reinforcement treatment, cathodic protection installation, concrete reinstatement and installation of GRP drip angles to improve long-term water management. The project required a highly coordinated delivery strategy due to restricted access, live traffic constraints and environmental controls associated with hydro-demolition operations. |
The Solution
The repair programme was delivered in controlled phases to maintain bridge stability and ensure safe working practices throughout. Where practical, deteriorated concrete was removed using hydro-demolition techniques to provide a clean substrate and minimise damage to surrounding sound concrete and reinforcement. Smaller or restricted areas were broken out manually.
The Outcome
Shotcrete Services Ltd successfully delivered the bridge abutment repair works to programme while overcoming signifi cant access, environmental and logistical
challenges.
The completed repairs restored the structural integrity of the bridge abutments and implemented long-term durability enhancements through cathodic protection
and improved water management systems. The project demonstrated our capability to deliver complex structural repair schemes within constrained live infrastructure environments, making the business a reliable delivery partner for Tier 1 contractors operating across the highways and civil engineering sectors
