Access tracks & haul roads
Typically the largest single area of disturbance, running for kilometres through moorland. Cut-and-fill construction leaves exposed verges and embankments on steep cross-slopes.
Sector Solution — Energy & Infrastructure
Wind farm reinstatement seeding, delivered across the UK.
Vegetation reinstatement for onshore wind farm developers and EPC contractors. Hydroseeding, erosion control and moorland grass restoration on access tracks, cable trenches, crane pads, borrow pits and construction compounds — working within your CEMP and under ECoW supervision.
The Challenge
Reinstatement is a programme risk, not an afterthought.
Onshore wind farm construction disturbs large areas of sensitive upland terrain. Access tracks, turbine foundations, cable trenches, crane pads and temporary compounds strip vegetation and expose subsoil or peat across sites that may span hundreds of hectares. Reinstating these areas to the standard required by planning conditions, Construction Environmental Management Plans and Ecological Clerk of Works sign-off is a significant programme risk.
Regulatory pressure is increasing. Biodiversity net gain becomes mandatory for Nationally Significant Infrastructure Projects from 2 November 2026, requiring a minimum 10% uplift in biodiversity value secured for at least 30 years. In Scotland, NPF4 Policy 3 imposes peatland compensation requirements, and NatureScot's Good Practice during Wind Farm Construction guidance sets detailed expectations for peat handling, vegetation reinstatement and post-construction monitoring.
Getting reinstatement wrong means failed ECoW inspections, delayed commissioning, planning condition breaches
and, on peat sites, ongoing erosion that undermines the carbon payback case for the entire project.
Site Areas
Where reinstatement is needed on a wind farm site.
Wind farm construction creates a patchwork of disturbed ground across upland landscapes. Each area presents distinct seeding and erosion control challenges — and each is priced, programmed and treated differently.
02 / 06
Cable trenches
Narrow, linear corridors connecting turbines to the substation. Backfilled trenches settle unevenly, and the reinstated surface must match surrounding topography to maintain hydraulic flow.
03 / 06
Crane pads & turbine bases
Large, compacted hardstanding. Decommissioned pads require soil decompaction and careful seedbed preparation; repowering projects need full reinstatement alongside new foundations.
04 / 06
Borrow pits
Excavated on site for aggregate, leaving steep, exposed faces of subsoil or rock — highly vulnerable to erosion and difficult to access with conventional seeding equipment.
05 / 06
Laydown areas & compounds
Large, compacted surfaces used during construction that need breaking up, soil amelioration and reseeding to re-establish vegetation cover after the build phase ends.
06 / 06
Substation compounds
Permanent infrastructure footprints with disturbed perimeters that require reinstatement to match surrounding habitat conditions and satisfy planning obligations.
Our Approach
How CDTS North & West delivers wind farm reinstatement.
Five disciplines, applied consistently from tender through to post-commissioning monitoring.
01
Equipment matched to upland access
Remote upland wind farm sites rarely offer the road access needed for large lorry-mounted equipment across the entire project. We operate a fleet of six hydroseeders ranging from a 6,000-litre Finn lorry-mounted unit to 2,000-litre towed machines. The smaller towed units can be pulled behind site vehicles along access tracks and across rough terrain to reach turbine locations, borrow pits and cable routes that a lorry cannot access.

Throughput

02
Seed mixes specified to your site
Upland wind farm reinstatement typically requires moorland grass, acid grassland or heather-rich mixes reflecting the surrounding plant communities. We work with your ecologist's specification to source and apply the right mix — a bespoke blend of heathers, bilberries and moorland grasses matched to local species, or an NVC-derived community prescription. Hydroseeding delivers uniform seed distribution across large, irregular areas that conventional drill seeding cannot reach.

03
Erosion control on steep & exposed slopes
Borrow pit faces, track cuttings and embankments are often too steep for conventional seeding or erosion control blankets. Bonded Fibre Matrix is applied hydraulically and fills surface voids around rock outcrops and existing vegetation that rolled geotextiles cannot conform to. BFM delivers up to 99% soil-erosion reduction on slopes as steep as 1:1, protecting the seedbed during the critical establishment period.

Soil preparation & ameliorants
Compacted crane pads, laydown areas and borrow pit floors present hostile conditions for seed establishment. We carry out seedbed preparation using power harrows, rotovators and stone buriers to decompact soils and create a suitable tilth before seeding. On acidic peat substrates, lime and fertiliser applications follow the project ecologist's specification, with rates and restrictions adhered to precisely.

Working within your CEMP
We operate as part of your site management team, working within the CEMP and under ECoW supervision. Reinstatement is programmed to align with construction phasing, so areas are seeded as they become available rather than left exposed until the end of the build. This reduces cumulative erosion risk and supports compliance with planning conditions that require progressive reinstatement.

Why CDTS North & West
Chosen for reinstatement on the UK's largest upland sites.
01
Fleet built for remote upland sites
Six hydroseeders from 2,000 to 6,000 litres mean the right machine reaches the right part of your site — from a lorry-mounted unit treating kilometres of track margins to a towed unit pulled to a borrow pit on a single-track access road. Full fleet detail on the specialist equipment page.
02
Proven at wind farm scale
Over 1,000,000 m² hydroseeded on a single wind farm project (Clyde), with further completions on sites in Scotland, Wales and southern England. This is not a contractor learning on your site.
03
UK-wide coverage from a national base
Despite the name, CDTS North & West operates across the UK. Our wind farm project list spans South Lanarkshire to Kent, with BESS projects alongside reinstatement work.
04
Moorland & upland seed-mix expertise
Experience sourcing and applying bespoke upland mixes including heathers, bilberries and moorland grasses, working to ecologist specifications and NVC-derived prescriptions — not off-the-shelf amenity blends.
05
BFM erosion control for hostile slopes
Borrow pit faces and track cuttings need more than grass seed. We apply Bonded Fibre Matrix hydraulically to slopes as steep as 1:1, providing immediate erosion protection that rolled blankets cannot achieve on irregular upland surfaces.
06
Aligned to your CEMP & ECoW
We programme reinstatement to align with construction phasing — progressive seeding as areas become available, not end-of-build scramble. Reduces cumulative erosion risk and supports planning-condition compliance.

Common Questions
Questions from wind farm developers & EPC contractors.
Answers drawn from 20+ years of UK hydroseeding projects. Anything we haven't covered? Send it through with your enquiry.
Access tracks and haul roads, cable trenches, crane pads, turbine bases, borrow pits, laydown areas, temporary construction compounds and substation compounds all require vegetation reinstatement following construction. Each presents different challenges in terms of slope, substrate and access. We have equipment suited to all of these.
Yes. Standard hydroseeding
works on moderate slopes, and for steeper gradients up to 1:1 (45°) we apply Bonded Fibre Matrix
hydraulically. BFM fills surface voids around rock and existing vegetation that erosion control blankets cannot conform to, delivering up to 99% soil-erosion reduction.
Seed mixes are specified by the project ecologist to match the surrounding plant communities. Typical specifications include moorland grass, acid grassland and heather-rich mixes. We have experience applying bespoke blends of heathers, bilberries and moorland grasses, as well as NVC-derived community prescriptions. More on ecological seeding.
Visible germination typically occurs within 7–14 days under optimal UK growing conditions, though timelines depend on altitude, season, weather and substrate. The mulch matrix applied during hydroseeding protects the seedbed from erosion and moisture loss during the establishment period — particularly important on exposed upland sites.
Yes — as standard. We operate within the project's Construction Environmental Management Plan and under Ecological Clerk of Works supervision. Reinstatement is programmed to align with construction phasing for progressive site recovery.
BNG becomes mandatory for Nationally Significant Infrastructure Projects from 2 November 2026, requiring a minimum 10% biodiversity uplift secured for 30 years. Reinstatement seeding is distinct from BNG habitat creation, but the two must be coordinated within the project's biodiversity gain plan. We deliver both reinstatement seeding
and BNG-compliant wildflower and habitat seeding.
Our fleet includes towed hydroseeders from 2,000 to 3,500 litres that can be pulled behind site vehicles along access tracks and across rough terrain. For areas with road access, the 6,000-litre lorry-mounted hydroseeder treats 2–3 hectares per day. Full fleet on the specialist equipment
page.
No. Despite the name, we operate UK-wide. Wind farm project experience spans from South Lanarkshire and the Isle of Arran in Scotland, through North Wales, to Romney Marsh in Kent. Request a quote for any UK location via the quote page.
