Highway & Rail Embankment Stabilisation
SEEDING SPECIALISTS
Rapid vegetation establishment on steep earthworks: reducing erosion risk, protecting assets, and supporting compliant project close-out across the UK.
Newly constructed highway cuttings and rail embankments face immediate erosion risk that can delay handover, trigger environmental fines, and create safety hazards. Without rapid stabilisation, rainfall washes exposed topsoil into drainage systems and watercourses, threatening project programmes and regulatory compliance.
CDTS delivers fast, compliant embankment stabilisation for highways authorities, rail infrastructure contractors, and Tier 1 civil engineers across the UK. Our hydroseeding and Bonded Fibre Matrix (BFM) methods establish protective vegetation on steep slopes within possession windows and tight construction schedules, reducing erosion by 99% from day one.
Where Embankment Stabilisation Is Required
Embankments and cuttings appear throughout highway and rail projects, often with steep gradients and restricted access that complicate vegetation establishment. Typical applications include:
New highway construction
BFM and hydroseeding deliver rapid cover on exposed embankments up to 2:1 gradient.
Rail corridor works
Our range of hydroseeder's provides precise application in access-restricted locations without disrupting rail operations.
Widening and improvement schemes
Hydroseeding establishes protective vegetation quickly, often achieving germination within 7 days during growing season.
Security and noise bunds
We hydroseed motorway bunds, counter-terrorism barriers, and acoustic embankments to meet both functional and landscape requirements.
Our Recommended Methods
We establish native woodland on embankments by sowing tree and shrub seeds directly onto prepared ground. Seedlings develop stronger root systems than planted saplings, anchoring slopes against erosion and subsidence over time. This method is particularly effective on steep embankments where planting crews face safety constraints, and provides ecological value alongside structural reinforcement.
Direct tree seeding for long-term stabilisation
For moderate slopes and verges, we hydroseed using reinforced mulch slurries tailored to gradient and exposure. This method covers large linear sites efficiently, delivering uniform seed distribution and faster germination than broadcast seeding on engineered slopes. The hydraulic mulch layer protects seed from erosion and bird predation while retaining moisture to accelerate establishment. Typical germination occurs within 7 to 14 days during growing season.
Standard hydroseeding for general embankments
Bonded Fibre Matrix is a spray-applied erosion blanket that bonds to soil on contact, providing immediate protection on slopes up to 2:1 gradient. We apply BFM when standard hydroseeding won't hold on steep embankments, achieving up to 99% erosion reduction from the point of application. Our 6000L lorry-mounted hydroseeder applies BFM significantly faster than manual blanket installation.

Why Highway and Rail Contractors Choose CDTS
We have stabilised embankments and cuttings on the West Coast Main Line, A483 highway schemes, and motorway widening projects across the North West and North Wales. Our fleet and experience match the scale and safety requirements of major infrastructure projects.
Our team understands possession planning, traffic management constraints, and the programme pressures that make rapid stabilisation critical. We mobilise to site quickly, complete works within agreed windows, and deliver measurable erosion reduction that protects your environmental compliance and project handover.
Projects are completed by CHAS and Constructionline Gold accredited teams, with full insurance and environmental policies available for tender submissions.
