Our Four Core Seeding Methods
CDTS North & West delivers proven vegetation establishment solutions for construction, infrastructure, and restoration projects using four specialist methods:
Hydroseeding – Rapid coverage for slopes and large-scale areas, ideal for tight timescales
Conventional Seeding – Cost-effective establishment on accessible ground with standard equipment
Wildflower & BNG Seeding – Species-rich habitats designed to meet Biodiversity Net Gain and planning obligations
Direct Tree Seeding – Establishing native woodland from seed on hostile substrates where conventional tree planting would fail
Every method is supported by specialist equipment, 30+ years of site experience, and full industry accreditations.

Where CDTS Delivers FOR TEAMS
Typical Applications
CDTS North & West provides hydroseeding and erosion control across infrastructure, development, restoration, and public sector projects where rapid vegetation establishment protects programmes and ensures compliance. We work on schemes ranging from major highway embankments and railway possessions to housing POS packages, quarry restoration, and local authority amenity projects. Our equipment and methods are selected to match site constraints—from 6000L lorry-mounted units on open motorway works to compact 2500L hydroseeders for restricted access and sensitive locations.
Highway and Motorway Embankments
Highway slopes face immediate erosion risk from rainfall and runoff, threatening programme handover and triggering environmental compliance issues. CDTS North & West hydroseeding with BFM provides rapid stabilisation within 24 hours of application, protecting bare earthworks before vegetation establishes. Our 6000L lorry-mounted units cover extensive embankments efficiently, meeting Highways England specifications for germination rates and minimising lane closure requirements. Evidence: 99% erosion reduction on 2:1 slopes, with full vegetation cover achieved within 6-8 weeks on major schemes.
Railway Cuttings and Lineside Vegetation
Railway projects operate under strict possession windows where delays cost thousands per hour and track protection is non-negotiable. CDTS North & West mobilises compact 2500L towed hydroseeders for restricted railway access, completing large-scale seeding within tight possession timeframes. Our teams work to Network Rail safety standards with full RISQS awareness, delivering rapid slope stabilisation that prevents soil migration onto track infrastructure. We've completed multiple schemes within overnight and weekend possessions, protecting programme-critical handover dates.
Utility Corridors and Pipeline Routes
Pipeline and utility schemes require rapid reinstatement across kilometres of varied terrain, often with environmental permit conditions and agricultural landowner agreements. CDTS North & West provides mobile hydroseeding capacity to follow construction phases, reinstating topsoil with appropriate grass or wildflower mixes within days of final grading. Our equipment handles restricted access corridors and transitions seamlessly between agricultural land, road verges, and sensitive habitats. This protects clients from extended reinstatement periods and helps satisfy regulator and landowner sign-off requirements.
SUDS Attenuation Ponds and Swales
SUDS features combine steep engineered slopes with environmental compliance requirements—a combination that creates erosion risk and potential pollution incidents. CDTS North & West applies specialist grass mixes designed for wet conditions and periodic inundation, with BFM erosion control on steep pond sides (often 1:3 or steeper). Our hydroseeding prevents sediment washout during establishment, protecting water quality and satisfying Environment Agency discharge consent conditions. This ensures SUDS assets function correctly from practical completion and meet building control sign-off requirements.
Wildflower Meadows for BNG Compliance
The mandatory 10% Biodiversity Net Gain requirement means planning permission now depends on verifiable habitat creation, with ecologist sign-off required before discharge of conditions. CDTS North & West delivers proven wildflower establishment using local-provenance seed mixes tailored to site soil conditions and BNG metric requirements. We manage the critical establishment phase—soil fertility reduction, weed control, and appropriate sowing technique—that determines whether habitats achieve target condition scores. Our track record includes multiple schemes where BNG sign-off was achieved on first ecological assessment, protecting developer programme and avoiding costly remediation.
Acoustic Bunds and Boundary Screening
Acoustic bunds present steep sides (typically 1:2 to 1:3) requiring immediate erosion protection and rapid visual screening for neighbouring properties and highways. CDTS North & West hydroseeding with bonded mulch provides instant stabilisation and fast germination, transforming bare engineered soil into green slopes within weeks. This addresses both technical risk (preventing gullying and sediment runoff) and commercial pressure (improving visual impact for sales and planning compliance). Our methods work on the challenging gradients typical of acoustic earthworks where conventional seeding often fails.
Landfill final capping and restoration phases
Landfill operators must satisfy Environment Agency permit conditions for final capping, with vegetation establishment critical for controlling infiltration and preventing leachate generation. CDTS North & West hydroseeding protects cap integrity—our method requires no heavy machinery trafficking that could damage liner systems or compromise engineered layers. We establish robust grass cover that reduces rainfall infiltration by up to 40% compared to bare soil, satisfying EA surrender conditions. This enables permit closure and ends the ongoing monitoring and financial liability of unclosed sites.

Featured Projects
Proven Delivery Across Sectors
Caernarfon Bypass
Completed: 2024
Location: Caernarfon
Sector: Highways
Client: Tilhill
One of our largest single schemes in North Wales. Hydroseeding across 60+ hectares of new road embankments, cuttings and verges on the Caernarfon bypass. The scale of the project required our 6000L lorry-mounted hydroseeder to maintain programme, with seed mixes specified to suit the local conditions and ecological requirements of the surrounding landscape.
Clyde Windfarm — Large-scale wind farm hydroseeding
Client: Blackwells
Sector: Energy/Wind Farm
Location: South Lanarkshire
Year: Multiple Phases
Hydroseeding across 60 hectares at the Clyde Windfarm complex in South Lanarkshire — one of the largest onshore wind farms in the UK. Wind farm construction strips vast areas of vegetation across exposed upland terrain, and rapid re-vegetation is essential to control erosion, stabilise access tracks and borrow pits, and meet planning reinstatement conditions. CDTS has delivered multiple phases of hydroseeding across the Clyde Windfarm North and South sites, applying seed and mulch hydraulically to areas that are inaccessible to conventional seeding equipment. The scale of this project — 60 hectares of hydroseeding on a single site — demonstrates our capacity to deliver programmes that match the demands of major energy infrastructure.
Cheshire Green - Infrastructure and landscape planting
Client: Jones Bros Civil
Sector: Infrastructure
Location: Cheshire
Year: Ongoing
Hydroseeding and conventional seeding across 10,000m² plus the planting of 6,000 trees and shrubs at a major new infrastructure and employment site in Cheshire. A very wet site demanded careful timing and equipment selection to avoid ground damage while maintaining programme. All seeding and planting is establishing well despite the challenging ground conditions.
Tarrington Wetlands — Wetland habitat creation
Client: Bentleys
Sector: Wetland Restoration
Location: Herefordshire
Year: 2024
Hydroseeding, conventional seeding and wetland plug planting across approximately 2 hectares at Tarrington in Herefordshire, including the installation of 15,000 wetland plug plants. Wetland creation projects require specialist knowledge of hydrology, species selection and establishment techniques, particularly where the aim is to create functioning wetland habitat rather than simply covering ground with vegetation. CDTS combined hydraulic and conventional seeding methods with hand-planted wetland plugs to establish a diverse, multi-layered habitat. This project demonstrates our ability to deliver integrated ecological outcomes where the specification goes beyond standard grass seeding.
