CDTS provides commercial hydroseeding services across the UK for contractors, developers, local authorities and landowners delivering large-scale seeding, erosion control and land restoration works. We work on highways, rail embankments, housing developments, landfill restoration, SUDS schemes, quarries and difficult slopes where conventional seeding is slower, less practical or harder to establish.
From our Cheshire base, we operate nationally with a fleet of six hydroseeders and experienced site teams. We select and apply seed, mulch, fertiliser and binder mixes to suit the ground conditions, specification and programme, helping vegetation establish quickly while reducing delays, access issues and remedial work.
Hydroseeding (sometimes called hydromulching or hydraulic seeding) combines seed, cellulose or wood-fibre mulch, a binder or tackifier, fertiliser and water inside a hydroseeder tank. The slurry is sprayed onto prepared ground by cannon or hose, where the mulch layer holds seed in place and protects the surface while vegetation establishes. For the method in detail, including germination times, coverage rates and specification guidance, see our guide to what hydroseeding is and how it works.
Hydroseeding is selected on UK construction projects for four reasons that conventional drilling and broadcasting cannot match:
Coverage speed
A single 6,000L tank load treats up to 3,000 m² in one pass. On a typical highway or restoration scheme, this compresses the gap between earthworks completion and seeding, protecting handover dates.
Erosion protection during establishment
The mulch component bonds to the soil surface immediately, reducing runoff velocity and shielding bare ground from rainfall while seed germinates. For higher-risk slopes, Bonded Fibre Matrix (BFM) extends this protection up to 99% C-factor erosion reduction on gradients to 1:1.
Uniform seed distribution
Hydraulic application delivers consistent seed coverage across irregular ground, eliminating the bare patches and uneven establishment associated with broadcast spreading on uneven terrain.
Access to difficult terrain
Slopes too steep for tractor-mounted equipment, remote corners, narrow corridors and active rail or highway environments are all reachable with hose-fed application.
We deliver hydroseeding across the project types where vegetation establishment carries direct programme, compliance or commercial risk.
Bare highway slopes face immediate erosion risk from rainfall and runoff once earthworks finish, often within tightly controlled access windows.
Hydroseeding with BFM protects the surface while vegetation establishes. The 6,000L lorry-mounted unit covers extensive embankments efficiently.
Rail schemes combine steep cuttings, restricted access and defined overnight or weekend possession windows.
The compact 2,500L towed hydroseeder can mobilise into confined access points and apply seed by hose across lineside slopes.
Engineered basin sides need vegetation establishment without allowing rainfall to wash seed or sediment towards the waterline.
Project-specific seed mixes are distributed uniformly, with BFM added where the erosion risk warrants greater surface protection.
Capped domes, quarry benches, spoil heaps and perimeter slopes combine large areas with irregular, access-constrained ground.
Hydroseeding establishes vegetation without trafficking heavy seeding plant across the full treatment area.
Ecologist-specified mixes must be distributed consistently across large or difficult-to-access habitat areas.
Hydroseeding applies specified wildflower mixes uniformly to support Biodiversity Net Gain delivery and Defra Metric target condition scores.
Public open space, attenuation basins, amenity areas and acoustic bunds need reliable establishment for adoption and planning requirements.
Hydroseeding covers large development areas and reaches the steep gradients typical of acoustic earthworks.
Energy works leave exposed ground across remote, upland and rural terrain, including access tracks, borrow pits and laydown areas.
Hydroseeding reaches ground around installed infrastructure where conventional machinery may not fit. Project references include Clyde Wind Farm.
Flood defence and water infrastructure schemes require vegetation reinstatement across engineered slopes with restricted plant access.
Hydroseeding applies seed and mulch uniformly while reducing trafficking on finished earthworks. Project references include Rhyl Sea Defences.
Hydroseeding fails on site when contractors use generic specifications, lack the right tank size for the access constraints, or cannot mobilise to programme. CDTS North & West removes those risks a large, dedicated hydroseeding fleet, project-specific specification, and a 30-year delivery record.
30+ years of UK delivery
Since 1991 we have hydroseeded over 10 million m² on motorways, A-roads, flood alleviation schemes, dams, wind farms, quarries, landfill sites and major housing developments across England, Scotland and Wales.
Vetted, accredited, insured
CHAS accredited (SSIP Approved Contractor, membership CHAS-29009949). Public liability £5 million, employers liability £10 million, contractors all risks £350,000 (AXA). Full RAMS and method statements supplied for every project.
Technical specification, not generic spraying
We review drawings, slopes, ground conditions and access before every project, then specify slurry composition, application rates and erosion control measures to suit the site. Where conditions warrant, we apply Bonded Fibre Matrix (BFM) or Engineered Fibre Matrix (EFM) for engineered erosion protection. Read our BFM guide.
Six-strong specialist hydroseeder fleet
We operate six hydroseeders, scaled to match site access and area:
6,000L Finn lorry-mounted hydroseeder for major highway, rail and restoration schemes 4,000L Finn trailer-mounted hydroseeder for mid-scale infrastructure works 3,500L, 3,000L, 2,500L and 2,000L twin-axle towed hydroseeders for restricted access, sensitive habitats and confined corners.
Multiple units can be deployed simultaneously on large schemes to compress programme timelines. View the full specialist fleet.
To see this process in action on a live highway scheme, view our A487 Machynlleth Bridge case study.
01
We review drawings, slopes, soil type and access constraints, then agree seed mixes, mulch rates and application areas with your team. Site surveys are available across the UK.
02
We confirm that soil quality, compaction and surface condition meet the specification. Where required, we deliver power harrowing, stone burying, rotovation or direct drilling using our seedbed preparation fleet.
03
Inside the hydroseeder tank we combine water, binder, mulch and seed to specified rates, agitating continuously to maintain a consistent slurry.
04
The slurry is sprayed by cannon or hose with overlapping passes, delivering uniform coverage at the correct application rate across the full treatment area.
SEEDING SPECIALISTS
Hydroseeding is priced per square metre: amenity grass typically £0.30 to £0.85 per m², wildflower and BNG mixes £0.45 to £0.90 per m², with BFM and EFM erosion control priced on application. Rates depend on seed specification, mulch type, slope gradient, ground preparation, access and total area.

Seeding Specialists
CDTS North & West operates from Alport Farm in Cheshire and delivers hydroseeding nationally. We regularly work across the North West, North Wales, the Midlands, Yorkshire and Scotland, with capacity to mobilise multiple teams simultaneously on large schemes anywhere in the UK. Recent projects include sites in Manchester, Liverpool, Chester, Wrexham, Stoke-on-Trent, Birmingham, Lincolnshire, Herefordshire, North Yorkshire and South Lanarkshire.
Visible germination typically occurs within 7 to 14 days under optimal UK growing conditions. Full vegetation cover takes 6 to 8 weeks depending on season, soil temperature and species mix. Hydroseeding does not make grass germinate faster than conventional seeding; its advantages are coverage speed, erosion protection, uniformity and access.
A 6,000L lorry-mounted hydroseeder typically treats 2,000 to 3,000 m² per tank load and covers 2 to 3 hectares per day on standard sites. Smaller 2,500L towed units cover 1 to 1.5 hectares per day but reach restricted areas larger machines cannot. With six hydroseeders, CDTS North & West can deploy multiple units in parallel on large schemes.
Standard amenity hydroseeding is effective on slopes up to 3:1 (around 18°). Bonded Fibre Matrix (BFM) extends this to 1:1 (45°), making hydroseeding suitable for near-vertical cut faces, dam embankments and quarry benches where other methods are impractical or cost-prohibitive.
Yes. Hydroseeding provides effective erosion control by bonding a protective mulch layer to the soil surface immediately after application. For standard slopes up to 3:1 the mulch alone delivers meaningful protection during establishment. For steeper slopes we apply BFM, which acts as a spray-applied erosion blanket delivering up to 99% C-factor erosion reduction. See our steep slopes and erosion control service and erosion control methods guide.
Yes. Hydroseeding suits wildflower establishment and Biodiversity Net Gain delivery, allowing precise application of specified mixes including locally sourced or low-germination species across large or difficult-access areas. We work from client-supplied ecological specifications or can advise on appropriate mixes for habitat targets and Defra Metric requirements. See our wildflower and BNG seeding service and the guide to achieving 10% Biodiversity Net Gain.
CDTS North & West operates UK-wide from its Cheshire base, with six hydroseeding units and capacity to mobilise multiple teams simultaneously. We regularly deliver hydroseeding across England, Scotland and Wales for highway, rail, utilities, restoration and development projects.
