One Solution for Every Spill
Align JV Case Study
Why Align JV chose to work with Pro Earth to protect the environment
OBJECTIVES
The Colne Valley Viaduct is arguably the most significant visible engineering feature on the Phase 1 route of HS2.
While delivering this project, Align JV – comprising Bouygues Travaux Publics, Sir Robert McAlpine and Volker Fitzpatrick - is using innovative methods to conserve and protect the environment. The objective is to deliver the HS2 vision - in particular that the viaduct should ‘tread lightly’ across this beautiful landscape.
ENVIRONMENTAL SOLUTION
To offer the maximum, belt-and-braces protection to the River Colne and the Colne Valley lakes during the construction period, Align JV chose a unique environmental protection solution from Pro Earth.
The hybrid absorbent booms attached to a silt curtain - pictured above in grey - contain a natural, sustainable, hydrophobic material that absorbs hydrocarbons and chemicals. Robustly manufactured in the UK, the booms are designed to stay in the water until Spring 2025. This means that as well as offering the ultimate protection for the
environment, they are a cost-effective solution too.
AT A GLANCE
The Project
HS2 contractor, Align JV is constructing the 3.4km-long Colne Valley Viaduct - the UK’s longest railway bridge.
The Challenges
- Environmental and public sensitivity
- Construction access
The Solutions
- Innovative construction methods for temporary and permanent works
One of the advantages of working with Pro Earth has been their collaborative approach.
The design of the booms has evolved, and we are confident we have the very best environment protection solution in place.

BENEFITS
Benefit One
Booms filled with a non-leaching, hydrophobic
material that absorbs hydrocarbons, and chemicals in the
event of a spill breaching the primary containment measures on the jetties
Benefit Two
Booms also mitigate against the effects of potential silt migration
Benefit Three
In choosing the Pro Earth solution, Align JV has fulfilled an important HS2 objective: to give supply chain opportunities to SMEs
Benefit Four
Local manufacture means Align is also supporting UK industry
