Enviro Kerb System
Envirokerb
The new and improved range of recycled composite kerb drain solutions.
www.pds-plc.com
The Lightweight Envirokerb Range of products conform to Manual Handling Regulations, cutting out the cost of any mechanical handing equipment. Installation time is exceptionally quick on the whole Envirokerb System, as well as reducing the RISK of personal injury.
Lightweight
Each Envirokerb component has been designed to be installed manually. The Bridge drainage weighs as little as 9kg. The standard 305mm depth weighs only 15kg, the 385mm weighs 18.5kg and the 480mm weighs 24kg.
Chemical Resistance
The product is resistant to all forms of effluents found in highway situations such as road-salts, petrol, diesel etc.
Aesthetics
Envirokerb, through a policy of material and process development, has a finish almost identical to a standard concrete kerb. Further large investment in new tooling and production techniques has allowed for improved aesthetics over the original product. We are confident that we now produce a product that cannot be differentiated from concrete- unless you pick it up!!
System components
The Envirokerb system is complemented by a full range of additional components including drop kerbs, centre stones, lightweight gully chamber, rodding access units, radius units and numerous outlet possibilities.
Available in 165mm, 190mm 210mm (Structures) and 305, 385, 480, depths in both HB2 and 45 splay. The Envirokerb Range has been used on motorways, car parks, traffic calming, urban areas, train stations and now on structures and bridges.
Contents
The product has proven to be very strong, and to date we have experienced no breakages. Once in-situ the product has the appearance of concrete and blends exactly with existing kerb-lines. We would have no hesitation in recommending the product.

When launching our new product range in 2003 it became apparent that designers and clients require confirmation of the longevity and quality of the Envirokerb range. It was therefore imperative that PDS PLC made large investments in all required standards, Quality Assurance and Accreditation.
Due to success in Ireland where we are the market leader in the supply of Combined Kerb Drainage, and with a clear objective to supply markets in mainland Europe it was essential that any Accreditation we obtained was recognised in Europe and not just the UK. We therefore chose to CE mark all our product ranges.
Further Benefits - On the A1073 Spalding to Eye contract, the complete range of Envirokerb Units was delivered to site on 20 Artic loads - it was estimated that Traditional Concrete products would have required 80 Artic loads to deliver the same meterage.
This calculation can be carried out for your project.
This was done with the guidance of the Highways Agency and in partnership with Lloyds Register Quality Assurance. We are now very proud to hold the following certification:
EN1433 CERTIFICATION TO D400KN - EN1433 is a European Harmonised standard with an attestation level of 3. This defines how to test products and where to source NOTIFIED BODIES to oversee all tests. Tests covered in EN1433 include LOAD TEST (D400KN), WEATHERING TEST (R+) and also watertight test (an essential requirement of EN1433). ISO9001 Quality Assurance for the Design, Manufacture and Distribution of Combined Kerb and Line drainage. The above allow us to issue a Declaration of Conformity and to CE Mark our product range- Under European legislation this is the only Mark relevant under a Harmonised Standard - No other Mark SHOULD BE SPECIFIED as this can undermine the CE mark and lead to confusion. ENVIROKERB is fully compliant with all revisions of the HIGHWAYS AGENCY Interim Advice Note IAN117/08 and clause 516 of the Specification for Highways Works. PRODUCT ACCEPTANCE - PDS have supplied and are supplying the largest contracts in the UK and Ireland. This includes Highway Agency, National Roads Authority and Department of Environment contracts. Contracts in Germany, Italy, Slovakia, Spain, Switzerland and more recently South Africa. A comprehensive list is available to download on our website. Envirokerb is type tested in accordance with 89/106/EEC attestation systems 3. Management system of production location(s) are assessed to the requirements of ISO 9001:2000 and additional product focused audit trails and samples are carried out, to the intent of 89/106/EEC attestation system 1.
Environmental Benefits
We are often asked about our GREEN CREDENTIALS. Initially we felt that any research or figures produced would be very subjective dependant on which organisation was chosen to carry out the tests. Then we were approached by ENVIROLINK NORTHWEST (A public sector organisation) who suggested that a new standard PAS2050 (Publicly Available Standard) would offer clarity to any research.
PDS use recycled materials that would otherwise be destined for landfill within the UK & China. If sent to landfill the material we use, for example, to manufacture our Envirokerb range, would take between carbon footprint. In the UK it is estimated that we have only 7 years of landfill left! Existing Combined Kerb Drainage systems manufactured in traditional materials rely heavily on natural resources. There are additional logistical concerns on the transportation of these materials through the smaller countryside communities in the UK. These products are heavy, brittle, difficult to recycle, and carry installation. We are happy to supply clients with carbon calculations and carbon costs for haulage on projects using our materials.
750-1000 years to degrade. PDS can help your company decrease its a number of on-site safety issues associated with their handling and
PAS2050 - the assessment of the lifecycle greenhouse gas emissions of goods and services was developed in response to an industry desire for a consistent method of quantifying CARBON FOOTPRINT cost. PDS PLC successfully completed a lifecycle study as defined by PAS2050 and are proud to be able to claim that our products really are GREEN!.
Environmental Considerations
Concrete / Polymer concrete products
ll raw materials are newly quarried A using large machinery. roducts include cement or resins which are all P manufactured for the process. Products are moved around production facility, and around site using forklifts - less on a pallet than Envirokerb. AULAGE - this is one of the major considerations - There is 26 H tonnes of raw material, or finished product on an articulated lorry. The meterage of product is much less than our lightweight product. We would be happy to carry out haulage calculations for your client. ost concrete products will be installed by machinery due to M excessive weight - this is a high carbon cost.
Envirokerb
The UK sourced raw material was originally manufactured for other products. There is therefore no extra carbon cost for our products. Kerbs are manufactured using heat and moulding. This would be our biggest carbon factor. roducts are moved around production facility and around site using P forklifts - but due to light weight we have more units per pallet. HAULAGE - we can now carry 1320 units per load (660mts), compared to 320 (160mts of Concrete kerb drains). This is the largest factor for consideration.
The full Envirokerb range is installed manually. Therefore the carbon cost is greatly reduced over concrete type products. Other considerations when using the Envirokerb may include the carbon cost of dumping the waste on landfill sites and its degradation over a 1000 year period. The other consideration would be the incineration of this plastic waste if it was not recycled into a new product.
www.pds-plc.com
The Envirokerb offers the perfect solution. At 15kg it is lightweight enough for manual installation. Of all the projects we have carried out so far we have not had a single breakage or chipping to kerbs and the product has proven to be stronger in all aspects than the traditional concrete kerbs.
Birmingham City Council Highways Dept
Lightweight - the lightest product on the market by up to 70% allowing easy installation. Durable - high impact resistant greater than traditional materials. Manufactured from recycled materials. Available in both 305mm, 385mm and 480mm depths in 45 SPLAY and HB2 profile. For use on motorways, trunk roads, car parks and most other urban areas. Conforms to EN1433 linear drainage systems D400KN loading. Full Quality Assurance.
Installation Guide
Envirokerb is manufactured to comply with the D400kn loading requirement of EN1433, an integral part of this standard is the installation detail used and the concrete surround/haunch.
1) Risk assessment should be carried out. 2) Excavate through to line and level. 3) Lay out units prior to installation to ensure all rodding access units and outlets are positioned correctly. 4) Start at outfall and work away, finished line and level should be pre-determined. 5) Sealant is to be applied to unit not yet laid then butt together keep joints clean of concrete bedding material. 6) Rear haunch - concrete should be a minimum st4 concrete with a 50mm slump to ensure the correct density. 7) PDS PLC suggest a very simple shutter system will reduce the amount of concrete used and will enable concrete density. 8) Asphalt can be laid to the bottom of outlets for a 125mm kerb-face, or to the watermark for 75mm/100mm kerb face. 9) Units should be cleaned prior to hand over. 10) Please use our inspection and test plan I.T.P. To ensure installation is correct as specified by the manufacturer. This can be included in your quality assurance manual. 11) Designers - to ensure your installation is correct please contact our technical department to request installation video/i.T.P.
t is imperative that the rear haunch is at the correct height, using a concrete with I the correct strength and slump. Standard concrete kerb laying material should NOT be used. If you are in any doubt please call the technical Dept. of PDS PLC. PDS PLC have launched an interactive installation guide- this can be viewed on the web, or on a smartphone. Please contact sales or visit www.pds-plc.com.
If asphalt pavement is present at rear of units the concrete can be adjusted accordingly, the concrete haunch can be lower. Any block paving adjacent to the kerbs should be restrained from movement on an epoxy or polymer modified mortar.

The designs carried by PDS PLC include the option of schematic schedules and CAD drawings incorporating the preferred product. This can be from a simple layout diagram up to a very complicated computer generated layout.
CPD Seminars
PDS are pleased to offer presentations to all Engineering/Civil Contractors and also to end clients/Authorities. This philosophy of working closely with the design engineers ensures that all our new developments and benefits are understood. It also enables PDS to obtain valuable feed-back on your requirements, and assists us in our policy of Continuous Product Development (CPD).
PDS PLC also has the facility to produce Interactive dvd Presentations.
Other products
PDS PLC are now a major manufacturer and supplier of a number of products for the Civil Engineering Industry. These include ENVIROCHANNEL Surface water drainage channels, ENVIRODECK Combined kerb drainage for Bridges and areas of shallow depth, ITKERB a Combined kerb drainage and cable duct system. Please see our website www.pds-plc.com for further information.

Due to the composite material used in the manufacture of Envirokerb giving excellent co-efficiency values, the hydraulic performance is improved over traditional materials. We have also incorporated three surface water inlet points offering a higher waterway area, designed to restrict the ingress of large debris.
PDS PLC has always offered a full design service for both bridges and roads.
PDS PLC are pleased (and in fact prefer) to carry out all Hydraulic designs on behalf of both the Designer and the Contractor. This service is free of charge on the Envirokerb road and bridge drainage range Systems. We feel that this ensures the contract incorporates the most cost-effective and hydraulically efficient depth/width drainage unit. It is a mistake to incorporate units that are over sized in your design as they may be ineffective at obtaining a self-cleansing velocity. Establishing the correct size of unit enables products that offer cost savings over large, heavy drainage units to be installed. In our experience, a large number of contracts are designed using ineffective sizes that struggle to drain the required areas, due to the velocity of run-off being too low. A quick reference chart is shown for both Splay and Half Battered units.
Intermediate size
PDS have a unique 385mm deep unit within the Envirokerb range. It was noted that there was a large Hydraulic gap between the 305mm and 480mm sizes. The 385mm offers a wider range and yet still weighs in at only 18kg - alternative products have no other option than to offer larger/heavier sizes.
Technical help
PDS PLC have great experience in designing Kerb Drainage Systems, especially ascertaining the most effective sizes required to efficiently drain your scheme. We therefore request your details/drawings are forwarded to our design department for a full Hydraulic review - This is a free of charge service!

Case Studies
PDS have successfully supplied some of the largest highway contracts in the UK and Ireland in the last 5 years. This includes Highway Agency, National Road Authority and Department of Environment contracts. A comprehensive list is available to download on our website.
We initially contacted the contractor HMCJV on the largest road project in Northern Ireland to discuss Bridge Drainage. At a meeting with Martin ONeill (Project Manager) we also took the opportunity to offer our Envirokerb Recycled Kerb Drainage for Roads. Due to the nature of the contract and the very close spacing of the Gully Gratings we found that in certain areas the Lightweight Kerb Drainage offered a cost benefit over the traditional kerb and gully method of construction. PDS were invited to meet with the designers, Arup to investigate the potential across the whole scheme. Eventually over 6500 mts of Envirokerb and Hydrodeck Bridge Drainage were supplied to HMCJV. M1 West Link, Belfast Client Contractor Consultant Roads Service HMCJV ARUP
...the installation rates on this job compared to other products is far superior; its a one part system instead of the usual two part system. Its also a lot less weight being plastic, the rate you could lay at is twice as much if not more than traditional concrete systems.... Birse Civils - Video Case Study.
This will be the second largest project carried out by this Birse CL site team following on from the Sunderland Radial route.
The site agent, Andy Moore has reported that due to the speed of lay, but mainly due to the lack of breakage the Envirokerb was his chosen product on the Darlington Eastern Transport corridor. The 100% guarantee against breakage has saved Birse up to 15% in new purchases but also the saving over re-laying when units are broken by site traffic.

Increasingly PDS PLC are supplying contracts with various products from our range. The Leeds Inner Ring Road is another project that shows why this benefits both the contractor, client and of course the supplier.
This project has removed traditional concrete kerb drains and replaced them with our Envirokerb lightweight Road Drainage and was also one of the first schemes to utilise the Envirodeck Bridge Drainage System. The contractor, Alfred McAlpine saw the benefit of using lightweight, non-metallic and strong drainage systems rather than using heavy, brittle and large concrete drainage products. Envirokerb gave them the added benefit of increasing the amount of 100% recycled products used on the scheme. The savings by value engineering the design has proven to be very worthwhile for Alfred McAlpine who have now purchased these products on numerous other schemes. Leeds Inner Ring Road Client Contractor Consultant Leeds City Council McAlpine (Carillion 2008) Mouchel
Alfred McAlpine take the Health & Safety and their environmental responsibilities very seriously.
PDS PLC have built up a number of close relationships with large contractors who use our Design department to Value Engineer schemes to obtain the most cost effective and beneficial solution to their surface water problems.
One of these contractors is CARILLION (Formerly known as Alfred McAlpine) who have recently incorporated our products on some Award Winning schemes. The Envirokerb Recycled Kerb Drainage has been re-designed into Leeds Inner Ring Road, M60 Manchester Widening, A30 Bodmin Scheme, the A1 Scotch Corner contract, the A12 Witham Bypass and the on-going M4 Widening at Cardiff. The Leeds Inner Ring Road also incorporates the Envirodeck Bridge Drainage system. Both parties have benefitted greatly from these arrangements by improving on design, saving on installation time, improving Environmental impact and of course a cost saving has to be made to make it a worthwhile partnership.
We enjoy a partnership arrangement with these contractors and they allow us to offer our Unique products to their clients.

The product is available as 150mm, 220mm and 310mm wide with various depths depending on the Kerb Profile required (75mm, 100mm or 125mm splay or HB). PDS PLC are the World leaders in Bridge Drainage, supplying over 90% of Structures in the UK and Ireland. Our reputation for quality of product and service has led to orders in Spain, Switzerland, Italy, Abu Dhabi, Singapore, Germany and recently the Czech Republic. It was always our ambition to increase our range of lightweight, Environmentally friendly products and as our International business grows this becomes much more important.
Three additions to Envirokerb Range. Manufactured as a high strength one-piece monolithic unit. Ideal for areas where construction depths are limited i.e concrete slabs, Bridges, roads built as a slab or structure, underpasses and above culverts. 3 widths dependant on Hydraulic run-off. Allows continuity of Envirokerb drainage from carriageways to structures. Sub-surface drainage facility to help drain asphalt matrix. Fully compliant to EN1433 D400KN for Kerb Drainage Systems. Lightweight for installation advantages (19kg for heaviest product). Non-Metallic and therefore non-oxidising.

The NEW Envirokerb Bridge Drainage unit has been manufactured to supersede Heavy Ductile Units. There are a number of factors we need to establish to very quickly ascertain the width and depth required.
Depth is dependent on the kerb profile and upstand this will either be 75mm, 100mm or 125mm with the road construction depth determining the final full depth (see installation page 24). Width is based solely on the Hydraulic flows anticipated in conjunction with the longitudinal gradient on the deck. This is very easy for PDS to determine from a plan layout drawing showing road levels and a cross-section, then using our in house flow calculator we can size the units (chart alongside for quick reference) allowing us to offer the most Hydraulically (and cost) effective width. Please call our Technical department as we are more than happy to carry out calculations as part of our free of charge design service.
All calculations are based on the Mannings Equation which offers the most effective formula for low gradients.
Design Service
Our free design service offers huge benefits! The designs carried by PDS PLC include the option of schematic schedules and CAD drawings incorporating the preferred product. This can be from a simple layout diagram up to a very complicated computer generated layout. PDS PLC also has the facility to produce INTERACTIVE DVD PRESENTATIONS. We design bespoke solutions to contract-specific problems.

Case Studies
Initially launched to supply the large infrastructure programme in Ireland, the Envirokerb Bridge drainage very quickly became the first choice for bridge builders and engineers. With 3 widths we can now supply the majority of structures with this product range.
Build Phase - Envirokerb is lightweight for Installation, impact resistant from on-going site traffic and has long term durability ensuring the product will still look like new 2 years later at the opening ceremony! The Games Phase - Through the games the product will drain the structures as required. The durability will be evident throughout with no rusting, chipping or spalling. Legacy Phase - The 2012 Olympics has to deal with the legacy left for future generations. Therefore roads and bridges are either left for the benefit of the local community, or they are demolished and the material disposed of. Envirokerb Bridge Drainage is manufactured from material that takes up to 1000 years to degrade so longevity is not a problem. And any returned products can be recycled into raw material for other products manufactured by PDS PLC.

A 30 million bypass, delivered by Morgan Est on Transport for Scotlands behalf, involved the design and construction of a 3.5 mile road.
The NEW Shallow Envirokerb range was chosen to be incorporated onto the bridges on the A68 Dalkeith Bypass so that it could link directly with the Envirokerb Road Drainage System already installed on carriageways leading up to the structures. To the motorist the Bridge and Road units are indistinguishable. All are non-rust, lightweight, through-coloured, great impact resistance and with the appearance of Concrete they complement the surrounding area.

The development of ENVIROKERB Bridge Drainage was a direct result of the Irish road building Programme.
Whilst a number of Motorways were built, the existing smaller side roads needed to maintain their course. These roads are usually narrow, and Bridges are short. The Hydraulic Flows were low promoting PDS to produce a smaller, lighter and more cost-effective unit. The M3 project has built 65 new bridges with the majority using ENVIROKERB BRIDGE drainage. All designs were carried out by PDS PLC who became part of the Design team on the M3. Over 2000mts of bridge drainage has so far been supplied to this contract.

We used them on the A64 Hopgrove roundabout in York which is acknowledged internally, by client, consultant and by third parties to be a very successful and well presented projectIn summary I would happily use the product again.

The present Bonar Bridge was designed by Crouch and Hogg, built by William Tawse Ltd, and opened in 1973.
This bowstring girder bridge (built 1973) measures 339ft (103.4m) in overall length, replaces an 1893 bridge built by Sir William Arrol & Co Ltd, Glasgow. As part of a refurbishment scheme to this graceful structure in Invernesshire PDS PLC supplied over 500mts of Envirokerb Bridge Drainage installed to both kerblines and at only 10Kg each manual handling risks were drastically reduced for the installers. Being recycled composite and with an appearance almost identical to concrete the grey kerb line is retained and there are no on-going coating maintenance issues.

Installation Guide
ENVIROKERB BRIDGE drainage will normally be installed on a concrete deck or slab - This acts as your base. If you are to install on soft ground or compacted stone please see installation details for standard ENVIROKERB. The units will be bedded on ENVIROKERB BRIDGE bedding mortar or similar.
1) Layout units prior to installation to ensure all rodding units, outlets and expansion joint assemblies are positioned correctly. 2) We suggest that expansion joint assemblies are installed first as these cannot be cut to length. 3) Mix Envirokerb Bridge Bedding mortar as described on the bag, or on the product details available from the sales office. 4) DO NOT mix too much mortar as it is quick setting. Please experiment with the material first. Do not alter the mix ratio. 5) Install to line and level. It is advisable to find deck/structure high point and use this to determine the levels. Therefore reducing thickness of bedding mortar. 6) Sealant must be applied to unit yet to be laid and then butt together keeping joints clear of concrete bedding material. 7) Units can be cut with a power saw with either masonry or carbon blade. A mask, goggles and ear defenders should be worn. Cutting is much quicker than stone or metal units. 8) Units must be cleaned prior to handover.
The product has proven to be very strong, and to date we have experienced no breakages. Once in-situ the product has the appearance of concrete and blends exactly with existing kerb lines. We would have no hesitation in recommending the product.
