The first 100% composite lightweight combined kerb bridge drainage system.
- Strong & Lightweight Non-Metallic
- Precision Manufacturing
- High quality finish & appearance
- Manual installation
- Colour coding options - RAL colour option to compliment bridge construction (supplied as standard in concrete grey)
- Half Battered & 45 Degree Splayed
- New Anti-Slip Top Surface - additional pedestrian safety
- Wide Range of Widths & Depths Available
- Fully Compliant to BS EN1433
- Surface and Sub-surface Drainage Capability
- Significant weight savings to structure
- Non rusting - (no oxidization like metallic units). "Glass finish" invert for high hydraulic flows, reduction in silting and associated weed growth that causes system blockages, therefore less unscheduled maintenance
Pipeline & Drainage Systems PLC continues its policy of continual product development
Already market leaders in the design, manufacture and supply of bridge drainage systems, we are now introducing Envirodeck – A lightweight high quality composite combined deck drainage system, which maintains all the benefits of the continuous combined kerb bridge drainage concept, but also addresses system component quality, aesthetics and Health & Safety issues for the end user.
Combined Kerb Drainage System
Combined kerb drainage units are now widely used and specified on bridge decks whether they are new build or part of a refurbishment scheme.
Drainage is an essential requirement on all bridges. Deck mounted systems provide continuous surface & sub surface drainage and easily accessible maintenance.
Existing systems are traditionally metallic, which are heavy, raising Health & Safety issues for the installers. Metallic units place additional weight on the structure.
In addition, metallic units are prone to oxidization that can spoil the appearance of a structure, particularly as the systems are a highly visible element of the completed project. This results in on-going expensive maintenance. In addition the standard black coating (standard in all metallic systems) provides no de-markation between the carriageway and the kerb line.
Features and benefits
Health & Safety
Unit weights are reduced by over 50% to comply with the new manual handling guidelines and save precious dead weight on both new and refurbishment structures.
Anti-slip surface
A new anti-slip pattern is incorporated to comply with anticipated new legislation. The top surface has a "low tendency to slip" reading – impossible to achieve with metallic units and a health & safety benefit on bridges with pedestrian access where units may be subjected to pedestrian traffic. With growing concerns over the slip resistance of Manhole Covers many manufacturers have investigated how a “low tendency to slip” reading can be achieved.
Aesthetics
Envirodeck is a composite unit and will not oxidize or corrode unlike metallic units. Supplied as standard in concrete grey to match kerb lines and provide demarkation. They can also be manufactured in any RAL/BS colour to complement the bridge design and surroundings.
Hydraulics
The composite material produces a smooth high quality channel invert. This creates improved co-efficiencies, reduces drag gives higher flows and increases velocity to improve the self-cleansing ability of the system. This "glass like" invert prevents weed growth and silting - saving costs in unscheduled maintenance.
Chemical Resistance
Envirodeck is fully resistant to all types of chemicals in petrol, diesel and oil etc. Another benefit is that Envirodeck is not affected by UV.
Impact Resistance
Envirodeck is highly resistant to side impact. While EN1433 has no side impact test requirements, it is the main cause of failure in many kerbside type installations.
Unit Quality
Envirodeck is a precision made product, Unit finish, tolerances and aesthetics far exceed that of metallic systems. Smooth edges make the unit user friendly to handle.
Quality Assurance
PDS have full ISO9001 Accreditation (Management Systems), In addition and essential for full compliance to the EN1433 standard, our manufacturing facilities have full ISO 9000 series Accreditation and Quality Assurance.
EN1433
Envirodeck is fully compliant to the EN1433 specification (kerbside installations - Group 3 C250 min loading capacity) Envirodeck units are tested to the higher Group D400 loading class.
