Hydroseeding
SEEDING SPECIALISTS
Specialist hydroseeding for highways, rail, housing, quarries and land reclamation: designed for erosion control, BNG compliance and programme certainty
For more than 30 years we’ve delivered large-scale hydroseeding across the UK, from new bypasses and embankments to dams, landfills and business parks. Our fleet of six hydroseeders, including a 6,000L lorry-mounted unit and 2,500L towed machine, lets us cover everything from flat batters to steep, restricted access slopes efficiently and safely.
What Hydroseeding Delivers On Site
Hydroseeding establishes dense, uniform vegetation faster than broadcast seeding or manual methods, typically delivering 95% cover within 6–8 weeks. The sprayed mulch locks seed to the soil surface, shields against rainfall and wind, and maintains moisture through germination. Preventing the seed wash away common with conventional methods on slopes.
Programme Protection
Hydroseeding covers large areas quickly. A single 6000L tank load treats approximately 2,000-3,000m² in one pass. For projects with tight handover dates, this speed reduces the gap between earthworks completion and vegetation establishment.
Erosion Control
The mulch component bonds to the soil surface, reducing runoff velocity and protecting seed until root systems develop. For high-risk slopes, we apply Bonded Fibre Matrix (BFM), a spray-applied erosion blanket that delivers immediate protection without manual installation.
Cost Predictability
Hydroseeding is priced per square metre with minimal variation. Unlike erosion blankets, there are no installation labour variables. Coverage rates are consistent and measurable, making budget forecasting straightforward.
Where Hydroseeding Fits On Your Project
Hydroseeding is the default vegetation method for sites where speed, scale, or difficult terrain make conventional seeding or turfing impractical. It's the proven solution when you need to vegetate several hectares in days rather than weeks, when slopes are too steep for safe manual seeding, or when ground conditions won't support turfing equipment.
Whether you're managing highway slopes that require rapid erosion protection, restoring extractive sites with challenging substrates, or delivering SUDS infrastructure that must meet adoption standards, hydroseeding reduces programme risk and provides consistent results across varied ground conditions.
The method is particularly effective on linear infrastructure schemes, large-scale land restoration projects, and sites with restricted access where mobilising multiple seeding teams would be inefficient or create additional H&S risk.
Highway & rail embankments
Steep slopes (up to 45°) where conventional seeding or turfing is impractical or unsafe
SUDS ponds and basins
Rapid grass establishment on pond sides and bases to prevent erosion and meet adoption standards
Landfill restoration
Cost-effective vegetation of capped landfill domes and perimeter slopes
Quarry reclamation
Large-scale revegetation of benches, spoil heaps and quarry floors
Housing and commercial POS
Fast establishment for SUDS, attenuation basins and public open space to support adoption and sales progression.
Why Choose CDTS for Your Project?
Hydroseeding fails when contractors lack the right equipment, use generic specifications, or can't deliver to programme. CDTS removes these risks with a specialist fleet, site-specific technical planning, and 30 years of proven delivery across the UK's construction sector.
10 million m² seeded
Our team has delivered hydroseeding across motorways, A-roads, flood alleviation schemes, dams, wind farms, quarries and major housing developments for over 3 decades
30+ years experience
CDTS North & West holds CHAS accreditation and carries £5 million public liability and £10 million employers liability insurance. Full RAMS provided for every project.
6 hydroseeders
We operate six hydroseeders, from a 6,000L truck-mounted unit for major contracts to 2,500L towed machines for restricted access. That means we can treat large areas quickly while still reaching difficult slopes, batters and remote corners of the site.
How Our Hydroseeding Process Works
01
Site appraisal & specification
We review drawings, slopes, soil type and access, then agree seed mixes, mulch rates and application areas with your team.
02
Ground preparation
We check that soil quality, compaction and surface condition meet the specification, and can provide conventional cultivation where needed.
03
Mixing the slurry
In the hydroseeder tank we combine water, binder, mulch and seed to the specified rates, agitating continuously for a consistent slurry.
04
Application
The slurry is sprayed evenly by canon or hose, with overlapping passes to achieve uniform coverage and correct application rates.
