Materials Conservation

By far the biggest emitter of carbon emissions during bulk earthworks is the transport and disposal of materials off-site and importing of new materials to replace them. The more material we can retain and re-use on-site the less the carbon footprint will be.

Novel Ways of Re-using Site-won Excavated Wastes

We have an Environment Agency licence to establish mobile treatment facilities can devise novel ways of re-using site-won excavated wastes to deliver overall project objectives.

Concrete, hardcore and other solid inert wastes can be crushed and screened on-site to generate various grades of recycled aggregates that can be re-used during the development phases of projects. Asphalt wastes generated from planning road, car park and pavement surfaces can be used as feedstock for new asphalt material.

There may be a number of end-uses for excavated wastes (earth) to deliver the overall project objectives. It will need to be tested chemically (for contaminants) and geo-technically (for moisture content and particle size) to check if it is suitable. Site-won earth can be re-used on site for general fill purposes, to create noise bunds, visual screening or other landscaping features.

We also specialise in the in-situ remediation of contaminated land. Processing and reusing the land on-site can reduce or even eliminate the need for virgin sources and drastically reduce te cost and CO2 emission involved in transporting new materials to-site.

Testimonials

KKB performed safely, reliably and collaboratively during this project. Their management team were well organised, pragmatic, and diligent to work with and both we and our representatives on site are very satisfied with the services they have provided us

Owen Tucker, Project Development Director, Drax

KKB accomplished this development with no little skill and professionalism. Their innovative ideas for re-using waste material delivered substantial cost savings as well as contributing to the sustainability of the project

Lucky Gill, Managing Director, Gill Aggregates

The Kingsnorth project was challenging with several revisions to scope due to changes in ground conditions, the potential for UXO, abnormally inclement weather and ultimately the onset of the Covid 19 pandemic. Throughout KKB remained professional in their response to these changes, worked flexibly with us and other contractors and completed the work within the agreed timescales and to the expected quality. We would be happy to engage KKB for similar work in the future

David Ball, Development Director, Drax

We were very impressed with KKB’s performance and can-do attitude in delivering a series of complex packages of enabling works for our new Tilbury facility. Their management team adopted a consultative approach throughout to transform our concepts into reality. The two-year project was completed on-programme, to-specification and without any major issues. The standard of workmanship was also to a very high quality

Steven Wallis, Area Operations Manager, Tarmac

KKB successfully delivered these works earlier than programmed, through being proactive and continuously driving the project forwards. Their staff communicated well and ensured that the project team were aware of progress and any issues which arose were swiftly dealt with in a very practical way

Gareth Lane, Project Manager, Mott McDonald

Excellent disaster response within the hour from KKB Group who mobilised people, plant and equipment in a professional and safe manner. Nothing but praise for all KKB staff from the start to the finish of the job allowing the M20 to reopen within 24 hours

Asa Presneill, Director, Delta Ltd

KKB’s knowledge of remediation and partnering approach made them a valuable member of project team. They were able to apply significant resources in terms of manpower and equipment which allowed us to deliver the enabling phase on-budget and ahead of programme

Keith English, Contracts Director, John F Hunt

KKB’s experience of crushing, screening and site logistics has enabled us to efficiently extract and process minerals into high-quality secondary aggregates. Their ability to recycle inert wastes into specific sizes enables our plant to generate highways-grade CBM and enhance projects’ overall sustainability

Kelven Nicholls, Quarry Manager, Tarmac

KKB have a continual positive attitude and collaborative project team that are a credit to the company

Liam Disbury , Site Agent, Sisk

KKB’s commitment and professionalism has been exceptional. The reaction from handover has been amazing. You should all be very proud of yourselves and each other, an amazing achievement and rightly recognised by Highways England. I would also like to thank your families for supporting you all whilst working silly hours at short notice on a bank holiday weekend. The M20 is probably one of the most important routes in this country, hence at times like this you are some of the most important people in the country. Well done all.

Clive Leadbetter, MD of A One +

This site was deemed to be difficult and challenging to remediate. The entire team at KKB were brilliant and always had the expertise and resources to resolve any problems. I am delighted at the end results. In my opinion, the job couldn’t have gone any better

Bekki Eddy, Your Content Goes Here

We are very impressed with the professional approach of KKB to the management of all aspects of the earthworks and remediation for this project and look forward to working with the team again

Steve Horton, Area Manager (South) John Sisk

Tarmac and KKB have a true partnership, KKB provide Asphalt processing and recycle construction and demolition waste for Tarmac at 25 sites across the South. This provides flexibility for Tarmac and a consistent work load for KKB. Through collaboration KKB minimises transport costs whilst Tarmac ensure a quality product is available at all sites on demand. KKB provide advice and support and deliver innovative low cost solutions on request. I am extremely happy with how the relationship has developed it is working well for both parties.

Kevin Short, Continuous Improvement Manager, Tarmac

KKB Remediation carried out the works at Crawley Works for us. They were selected from a list of 4 tendering contractors as being the best bid and best price. They completed works in 23 weeks. Their price was around £2.7m including novated fees of our engineer. The works involved the introduction of the highways to the site and lengths of private road with relevant infrastructure. They were complete to time and cost parameters and to a good standard. Based on our experience of working with KKB Remediation we would have no problem recommending them for similar work opportunities

James Mawson, Exton Estates

Hanson Aggregates have been using KKB Plant for 20 years and we have always found their attention to detail, safe systems of working and professionalism ahead of the competition

Steve Chidgey, Hanson Aggregates

We were really impressed with all aspects of KKB’s performance on this load and haul project. Excellent communications with their Project Manager and Site Supervisor ensured the works were well organised while the experience and expertise of their site operatives helped deliver the project safely, on-time and to-specification

Lewis Coxon, CEMEX

We were impressed with the professionalism and attention to detail that KKB were able to bring to this project. Their experience and ability to liaise with our project team as well as outside agencies helped to streamline a complex and challenging enabling phase.
