S1E and McBreen Enviro UK Collaborate to Resolve Pipe Infiltration at the A30 Mammal Crossing

Written on 26 November, 2024

The project aimed to eliminate groundwater infiltration in a 900mm diameter concrete pipe under the A30 roadway, an essential mammal crossing allowing wildlife to safely cross this busy section of the Chiverton to Carland Cross route in Cornwall.

Background on the A30 Wildlife Crossing Project

The A30 Chiverton to Carland Cross upgrade is part of the Government’s Road Investment Strategy, aimed at improving the route to a dual carriageway standard.

During construction, significant groundwater infiltration was detected in a 900mm diameter concrete pipe serving as one of the mammal crossings. This pipe, surrounded by wildlife-proof fencing to guide animals safely under the busy road, required urgent attention to prevent structural damage and maintain its critical function.

Challenges in Concrete Repair

  • Severe Groundwater Infiltration: Affected 40 segments of the pipe (18 in one section and 22 in another)
  • Wildlife Protection: Required minimal disruption to preserve safe animal passage.
  • Safety Requirements: Demanded a skilled team trained in confined space operations and rescue and recovery.

Effective Solutions with K-Prema Mechanical Seals

S1E was consulted for a reliable repair solution and recommended McBreen Enviro UK for their expertise. The K-Prema Mechanical Seals were chosen for their durability and effectiveness in preventing water ingress.

Implementation Process

  • A team of McBreen Enviro UK specialists, certified in confined space work, installed the seals.
  • The seals were applied strategically to reinforce the 900mm pipe and halt infiltration, ensuring long-term functionality.

Results of the Pipe Infiltration Solution

  • Successful Infiltration Mitigation: The K-Prema Mechanical Seals fully addressed the groundwater issue, sealing the pipe and preventing further water ingress.
  • Timely Project Completion: Achieved within the set timeframe with minimal disruption.
  • Enhanced Infrastructure and Wildlife Conservation: The repaired crossing now supports ongoing wildlife movement and roadway stability.
