Seeding & Erosion Control Solutions for UK Projects

The Erosion Risk on Construction Sites

CDTS North & West provides specialist seeding and erosion control solutions that protect your programme, satisfy regulatory requirements and deliver measurable vegetation outcomes across the UK's most demanding construction and restoration sites.

Every construction project with exposed ground faces a version of the same question: what is the fastest, most cost-effective way to establish reliable vegetation that satisfies the specification and protects the programme?

The answer depends on your site conditions, not on a single method. Select the challenge closest to your project below, or use the decision guide further down this page to find the right starting point.

Who This Page Is For

If you already know the seeding method you need, our Services pages explain each technique in detail.

Procurement managers

Evaluating specialist seeding contractors for a framework or scheme appointment. You need evidence of accreditation, relevant experience, and the right equipment for the job. See our compliance and accreditation documentation or jump straight to requesting a quote.

Ecologists and environmental consultants

Specifying habitat creation for BNG, restoration plans, or ecological mitigation. You need a contractor who understands the Statutory Biodiversity Metric, local-provenance seed sourcing, and long-term habitat targets.

Quantity surveyors and commercial managers

Building prelims or value-engineering a vegetation specification. You need realistic cost data. Our hydroseeding pricing guide publishes current per-m² rates, and the comparison table at the bottom of this page shows where the biggest savings sit.

Site managers

With exposed slopes, tight handover dates, or erosion risk building ahead of the next wet season. You need a solution that works first time and does not create a return visit.

Which Solution Fits Your Project?

Not sure where to start? These five questions will point you to the right page.

Are your slopes steeper than 3:1?

Arrow point right.

Standard seeding methods struggle to hold seed on gradients steeper than 3:1 (18 degrees). If your embankments, cuttings or dam faces are steeper than this, start with Steep Slopes and Erosion Control. Bonded Fibre Matrix (BFM) applications extend effective seeding to slopes as steep as 1:1 (45 degrees).

Do you have BNG planning conditions to discharge?

Arrow point right.

f your development requires a Biodiversity Gain Plan under the Environment Act 2021, start with Biodiversity Net Gain Compliance. Wildflower and species-rich seeding delivers measurable habitat units at a fraction of the cost of off-site credits or plug planting.

Is your site a quarry, landfill or brownfield requiring restoration?

Arrow point right.

Hostile substrates, mineral waste and capped landfill all present specific challenges for vegetation establishment. Start with Land Reclamation for proven approaches to restoring these sites to condition.

Are you working on a highway or rail scheme with possession or programme constraints?

Arrow point right.

Embankment vegetation on transport infrastructure requires specialist access, fast coverage and compliance with MCHW or Network Rail specifications. Start with Highway and Rail Embankments.

Do you need SUDS features vegetated for adoption?

Arrow point right.

SUDS ponds, attenuation basins and swales need established vegetation before adopting authorities will sign them off. Start with SUDS Ponds and Flood Management, and note that hydroseeding SUDS slopes typically saves over 85% compared to turfing.

Working on a housing or commercial development?

Arrow point right.

Most developments need a combination of solutions across different zones: erosion control on embankments, amenity grass on public open space, wildflower areas for BNG, and SUDS vegetation. Start with Residential and Commercial Development, or send us your drawings and we will recommend the right approach for each area.

The Cost of Waiting

Proactive vegetation solutions consistently cost a fraction of the alternatives. The longer exposed ground is left untreated, the more expensive the fix becomes.

FAQs

  • How do I know which seeding or erosion control method is right for my site?

    The right method depends on four main factors: slope gradient, programme urgency, erosion risk and the specification requirements for your project. As a general guide, slopes steeper than 3:1 typically require hydroseeding or BFM rather than conventional methods. Sites with BNG planning conditions need specialist wildflower or species-rich seed mixes. Programme-critical schemes benefit from hydroseeding's faster coverage rates. Most projects use a combination of methods across different zones of the site. If you are not sure where to start, send us your drawings and we will recommend the right approach for each area.

  • Can you deliver different seeding methods across different zones of the same project?

    Yes. Most construction projects need more than one vegetation approach. A typical housing development might require BFM on steep SUDS embankments, conventional grass seeding on level public open space, and wildflower hydroseeding in BNG habitat areas. CDTS North & West delivers hydroseeding, conventional seeding, wildflower and BNG seeding, direct tree seeding and brush seed harvesting from a single appointment. This reduces coordination between trades and gives you one point of contact for the entire vegetation scope.

  • How much does specialist seeding cost compared to alternatives like turfing or erosion blankets?

    Amenity grass hydroseeding typically costs £0.30 to £0.85 per m². Wildflower and BNG mixes cost £0.45 to £0.90 per m². By comparison, turfing costs £15 to £25 per m² and erosion control blankets cost £8 to £12 per m² including installation. On a 2,000 m² SUDS pond, hydroseeding saves over £14,000 compared to turfing. On a 5,000 m² embankment, BFM hydroseeding can save £35,000 to £55,000 compared to blankets. See our full pricing guide at cdtshydroseeding.co.uk/hydroseeding-cost for current per-m² rates and worked examples.

  • What accreditations and insurance does CDTS North & West hold?

    CDTS North & West holds CHAS accreditation (membership CHAS-29009949, SSIP Approved Contractor), £5M public liability insurance, £10M employers liability insurance and £350K contractors all risks cover. All documentation is available on request for your tender submissions. Visit our compliance page for full details and downloadable documentation.

  • How quickly can you mobilise to site?

    CDTS North & West operates a fleet of six hydroseeders across the UK, including 6,000L lorry-mounted units for large-scale schemes and towed units from 2,000L to 4,000L for restricted-access sites. We can typically mobilise within a few days depending on current workload and season. A lorry-mounted unit treats 2 to 3 hectares per day on typical slopes, so most projects complete within one to three days of on-site work. 

Not Sure Where Your Project Fits?

Send us your drawings, specification or site photos. We will review them and recommend the right seeding and erosion control approach for each zone of your site. Most projects use a combination of methods, and CDTS North & West delivers them all from a single appointment.
