- Conforms to EN1433 linear drainage systems D400KN loading
PDS - Reputation built through innovation
Combined Kerb Drainage System
Whilst the Envirokerb drainage product range has proven to be a great success as the lightest, yet strongest unit on the market, it has always been the policy of Pipeline and Drainage Systems to continually improve their product ranges.
We have now been able to develop a method of manufacturing the Envirokerb that improves strength to an even greater level, reduces weight over the existing units, but also has the added benefit of dramatically improving the aesthetic finish of the product. Our production time has also improved leading to greater material output as we look to increase our market share.
The full range of units is to be introduced from January 2008 to be completed within 3 months. This will include 305, 385 and 480 depths in both Half battered and Splay profile.
Features and benefits
Lightweight
Each Envirokerb component has been designed to be under the 25kg one-man lift. The standard 305mm depth weighs only 15kgs, the 385mm weighs 18.5kg and the 480mm weighs 22kg.
Strong and Robust
The material used in manufacture is exceptionally strong and complies with BSEN1433 Group 3 kerb side installations load class D400kn.
Impact Resistant - PRODUCT GUARANTEED!
The product has the added advantage over traditional materials in being almost unbreakable from on-site handling and installation. The units are impact resistant, and do not suffer breakages when left exposed prior to pavement and road completion. In fact, PDS PLC Guarantee the product against breakage - please call for details.
One-piece
Standard kerbs are supplied in 500mm long (drop kerbs and centre stones are 457.5mm long) one-piece units. This eliminates the secondary operation of jointing two components, as required with some existing systems that are vulnerable to on-site breakage if left exposed.
Positive Interlock is available
The units are supplied plain ended as a standard which is "butt" jointed, but they are also available with a positive interlock between each module with the use of preformed male/female joints providing a method of installing to line and level. A watertight seal is achieved by applying Envirokerb sealing compound to the interface in both instances.
Asphalt Adhesion
It is common practice to pre-pitch the face of Kerbs to form a seal with the asphalt construction. Envirokerb allows for self-adhesion with hot poured asphalt offering both time and cost savings in installation.
Aesthetics
Envirokerb through a policy of material and process development has a finish almost identical to a standard concrete kerb. AESTHETICS HAVE RECENTLY IMPROVED DUE TO NEW MANUFACTURING TECHNIQUES.
Chemical Resistance
The product is resistant to all forms of effluents found in highway situations such as road-salts, petrol, diesel etc.
Quality Assurance
The system is fully compliant with BSEN1433 (Drainage channels for vehicular and pedestrian areas). PDS have also been issued with an ISO9001 certificate for the design, manufacture and distribution of specialist Kerb Drainage Systems. The Envirokerb range and PDS PLC are now compliant to ISO14001.
Improved hydraulic performance
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, and so designed to restrict the ingress of large debris.
System components
The Envirokerb system is complemented by a full range of additional components including drop kerbs, numerous centre stones, lightweight gully chamber, rodding access units, radius units and numerous outlet possibilities.
Environmental benefits
Envirokerb is made entirely from 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 750-1000 years to degrade. It is widely acknowledged that the construction industry has a major impact on the earth’s already dwindling resources. PDS use recycled materials PDS can help your company decrease its carbon footprint. In the UK it is estimated that we have only 7-10 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 a number of on-site safety issues associated with their handling and installation.
PDS are the first manufacturer to take the initiative in addressing these concerns by developing the Envirokerb Combined Drainage Kerb System. Envirokerb offers the client a number of environmental benefits.
Firstly the product is not reliant on natural resources and aggregates; secondly we utilise a composite of waste materials that would otherwise be destined for landfill sites; and finally, the product can again be recycled in the unlikely event it is no longer required.
Envirokerb is lightweight, non-brittle, strong and robust offering distinct advantages for on-site handling and installation.
