RECYCLED AGGREGRATE
Edburton’s recycled aggregates can be used for the construction of paths, roads and car parks either as a base or as a finished surface.
Edburton is now one of the primary high quality secondary aggregates suppliers in Sussex. All our recycled aggregates are produced in line with WRAP Protocols and The Specification for Highway Works.
Crushing and screening on site ensures we maintain our cost effectiveness, whilst limiting the impact our contracts have on the environment – largely recycling inert waste material that would otherwise be diverted to landfill.
Edburton’s recycled aggregates can be used for the construction of paths, roads and car parks either as a base or as a finished surface.
It has approval for use by all local authorities for whom Edburton carry out works and is available for sale to both private and commercial customers.

CASE STUDIES
SHELTER HALL, BRIGHTON
Client: BHCC
Contract value: £2,067,913
Edburton Contractors Ltd (ECL) acted as Principal Contractor in providing structural support to the main A259 at its junction with West Street and the Victorian seafront building known as Shelter Hall. Once the structural support works were completed ECL demolished the old building leaving the site safe and ready for development.
The environment was particularly challenging due to existing retail use of nearby arches, proximity to the i360 Observation tower, foot traffic along the beach walkway & road traffic / pedestrians on the A259 above.

Shelter Hall, Brighton, Phase 1 of 3
Client: BHCC
Client Contact: Leon Bellis, BHCC Project Manager
Contract Start: March 2017
Contract Completion: November 2017
Value: £2,067,913
Description of Contract & Scope
The project successfully delivered the enabling of the existing structure and surrounding landscape. This was vital for securing of the next tranche of funding in Phase 2 of the development, which was to be construction of the new Shelter Hall. This finally culminated in it’s completion with Phase 3 at the end of 2021 – all of which Edburton were the principal contractor for.
The environment was particularly challenging due to existing retail use of nearby arches, proximity to the i360 Observation tower, foot traffic along the beach walkway & road traffic / pedestrians on the A259 above.
Delivery Principles
ECL were engaged on a negotiated fee basis through its then Term Highways Maintenance Contract amended to suit the following disciplines:
- Design responsibility for Temporary Works
- Contract specific insurance to protect Clients’ risk
- Contiguously piled temporary retaining wall
- Screw piles and raking shores for permanent works pending construction of the new building
- Demolition of the old Shelter Hall Structure.
A dedicated design team was established prior to commencement including:
- Clients Representative – Leon Bellis
- Structural Engineers – HOP
- CAT 3 Structural Engineers – Tony Gee & Partners
- Contractors Team – Edburton
Regular meetings were held stating in January 2017 (see attached Q11.4 Diagram 01 for example) to ensure that strict control was maintained:
- Designers Risk Assessments and subsequent Contractors RAMS
- Surety of maintaining the integrity of the existing Highway Asset (A259)
- Public liaison
- Cost monitoring
- Future development of the new Shelter Hall building
Risk Management and Scheme Challenges
Through Early Contractor Input and holding regular progress / design meetings the following design methodology was jointly agreed and undertaken:
- Installation of a contiguously piled retaining wall with 600mm diameter piles up to 20.0m deep plus an RC capping beam. This was particularly challenging due to a 3.0t weight limit over a large footprint of the site
- Temporary RC bases within the original building supported on mechanical screw piles to be used for temporary propping prior to demolition
- Permanent RC retaining walls within the original building prior to demolition to be used as temporary works during demolition
- Installation of RMD Kiwkform raking shores
- Robotic and traditional demolition
Emergency Work Planning
Due to the nature of the environment and the proximity to the sea we had to react within 24hours to adverse weather warnings to protect against beach erosion which threatened to undermine the site compound which included all welfare, contractors and client offices, parking and storage.
Through ECL owning and operating its own haulage fleet, including a 42.0 GVW low loader along with a large fleet of 3.5t – 25.0t 360 excavators it was able to provide labour and plant at very short notice to replenish shingle
Innovation
Due to the 3.0t weight limit imposed on the Shelter Hall roof we had a very limited footprint within which to operate. Through early engagement with piling specialists Van Elle to select a compact but high performing piling rig, use of the lower prom for craneage and the storage of reinforcement we were able to keep all pedestrian and vehicular routes open as well as having zero effect on neighbouring business premises.
Outcome – Budget, Schedule and Quality
The project successfully delivered the ability for the next phase of the development which was to be construction of the new Shelter Hall.
The project demonstrated ECL’s ability to achieve BHCC’s key outcomes for this Highways Services Contract as follows:
- BHCC Key Outcomes: Project Achievements
- Environmental: Worked to correct beach erosion. Demolition waste removed for recycling.
- Cost management: Cost control undertaken closely with the Client
- Customer satisfaction: Successful completion facilitated the next phase of building works
- Quality assurance: Innovative techniques introduced to solve problems
- Safety: Pedestrians and motorists safely segregated from the works. All works planned and executed to ensure ongoing structural integrity
- Social value: No disruption to adjacent businesses. Prom remained open for pedestrians
- Schedule management: Works undertaken to planned programme
- Well planned Permits: Works undertaken under BHCC Permit
EGRETS WAY – LEWIS
Client: South Downs National Park
Contract value: £100,000
Date: 2019-2020
Description of works:
The project was undertaken along a shared usage path between Railway Lane and Ham Lane in Lewes in East Sussex, which forms part of the Egrets Way. These paths form a continuous traffic free route for walkers, cyclists and wheelchair users alongside the River Ouse. The path enhancements were undertaken on an existing footpath throughout, some of which had a narrow self-binding gravel surfaced path which needed to be widened, and the rest was an unsurfaced grass track.
A new width of 2.5m was to be achieved along the route wherever practicable in an approved limestone dust self-binding gravel surface to match the existing sections of Egrets Way. The path ran through a local nature reserve and open fields, as well as passing under the live railway line, the track under the bridge that allowed for this also required works which meant height restrictions and hand dig elements had to be contended with.
The open fields form part of a flood plain and special consideration had to be made for building up soft spots where required using a pre agreed 6F5 recycled aggregate. Finally, where the presence of trees required it, a cellular no dig solution was used to build up the path accordingly.
Method of operations:
The team scraped off all areas by hand or mechanically and prepared for a surface of 20mm x 2.5m Limestone Dust (6mm – 0mm) and a 150mm x 2.8m MOT Type 1 granular fill subbase – this was laid across a formation of 2.8m width and contained a Geotextile of 100 g/m2 strength laid between formation and the Type 1 granular fill. Allowance was made for a predetermined crossfall or altered to allow for a camber as topography dictated.
Tree lined narrow points along the path.
The team prepared the formation to receive 100mm cellular build up for a no dig solution. These were to be filled with Type 1 MOT and topped with 20mm x 2.5m Limestone Dust (6mm – 0mm).
Fencing, gates, and farm track remedial works. As the path ventured through two landowner’s properties, we were charged with replacing 4 no. gates, two were five bar galvanised and two were oak pedestrian ones with self-closing systems. As well as this we were required to construct around 20 meters of three rail soft wood post and rail fencing and an oak timber cattle crush with external kraal. These all required special consideration due to the surrounding wet land and specific farmer requirements.
Management of Risks and Interaction with the public:
As the path remained open for pedestrians wherever possible and often even when it wasn’t, the team had to allow for constant interaction with the public. Risks were mitigated for this by using the appropriate full or half height barriers, clear and new signage at multiple interaction points and only undertaking banked dumper movements of aggregate and muck away and always having banksmen at either end of the excavator.
Edburton Contractors prides itself on being a considerate contractor to the local community and the surrounding environment, so any deliveries were made outside of usual rush hours so as to minimise traffic disruption and engines had to be turned off as soon as the vehicle was stationary.
The team met regularly with Eco Consultants, SDNPA and Lewes Town Council as well as community volunteers to ensure they were adhering to the strict environmental considerations required as well as with the local landowners for any livestock movements.
Due to the proximity of wetlands and woodland banks we were constantly monitoring for any wildlife activity or associated evidence to ensure we stayed alert of potential interaction even after all surveys had been signed off as clear to proceed with the works.
