A QUALITY ABOVE THE REST Unite™ manhole coversUsing the very latest tools and software, the Unite range of manhole covers have been engineered for an extremely long life which in some instances has exceeded 20 years. Key to Unite’s longevity is minimising seat wear between covers and frames. The range has the stiffest cover structure in its class and on top of this, seating which is less vulnerable to any movement caused by covers flexing. We're so confident in Unite's performance, it's available with a 10 year warranty*. 
Create an installation that lastsSpecification clausesDownload and use our specification clauses in your future projects to ensure third-party installers use high-quality products. These documents provide clear, precise guidance for specifying our Unite and Highway product ranges, ensuring the best materials are always used in projects. By incorporating these clauses, you can significantly reduce the likelihood of product failure, extend the lifespan of ironwork installations, and minimise costly road closures and disruptions. 
> 1,500 Annual Average Daily Traffic (AADT)?With the introduction of CD 534 there were several key changes. This includes the requirement for E600 manhole covers to be installed in place of D400 covers where the Annual Average Daily Traffic (AADT) of light goods vehicles travelled on a road is greater than 1,500 in each direction. As a "rule of thumb", most A roads will have an annual average daily traffic number over 1,500 light goods vehicles. Full traffic data can be found for many locations around the UK on the Government website. 
Unite 10 year warrantyWhen installed with either our Unipak polymer resin bedding mortar, or Instarmac Envirobed® CD534 flowable bedding mortar, the Unite range is available with a 10-year product warranty*. Due to its unique design and overwhelming success in the local authority and utilities sector, Unite is the proven choice for durability and longevity for highway ironwork installations.

Universal beamA strength above the restUnite's high rigidity support beams, based on 'Universal Beam' otherwise known as I-beam technology, result in lower seat wear, improved longevity and lighter covers. Developed using advanced computer modelling and testing, this technology, incorporated in bridge and building construction, offers maximum strength and stiffness, dissipating the effects of forces exerted from high volumes of traffic. It also ensures that wear of cover seating is minimised (where the cover meets the frame), which is a common cause of failure in many rival covers. This all combines to provide the longest service life possible for the whole structure. 
Bedding material interlockMortar ‘gripper’ systemUnites flange surface provides a textured finish for bedding mortar to adhere to and the holes allow for interlocking between both sides. This will enable Unite to utilise the mechanical properties of bedding mortar, not just its adhesive characteristics. The bevelled frame edge as standard, prevents sharp edges from cutting into and breaking mortar away over time, as vibrations from traffic are transferred into the foundation. These unique, mortar-sympathetic, and advanced design features, allow Unite installations to stand the test of time in extreme environments. 
Large cover seating areaIncrease your asset lifeCover seating wear has been attributed as a major reason for failed manhole covers, which can lead to rocking, unwanted noise and eventually, failure. To further increase the lifespan of our Unite range, we have included a larger cover seating area. This increases the resistance to general wear by providing a large interface between covers and frames. In addition, we seat our covers as high up the frame as possible. This minimises frame movement, which otherwise would be transferred through the frame to the flange and bedding mortar, causing premature failures.
Potholes: More than a surface issuePOTHOLES - MORE THAN A SURFACE ISSUEHelping to find solutions to the UK's pothole problemPotholes across the UK’s road and highway network are a real problem. But did you know ironwork specification and selection can affect and even increase the likelihood of a pothole forming? Our new report explores;
How much can I save?Ironwork replacement typically takes around 3 hours*. Studies show the 2,000 users per hour of A-roads are delayed by an average of 4 minutes in roadworks**. This loss of earnings and productivity equates to over £3,000 per hour. The saving to society of not having a 3-hour long unnecessary manhole replacement is at least £9,000 and cuts the associated noise, dust and waste.

Flood and odour controlRetrofittable sealing platesUnite manhole covers are fully compatible with our range of No Leak and Low Leak sealing plates, thanks to the built-in internal accessory receiver. This internal skirt provides a sealing face to mate with different specifications of seal plate, depending on the application requirements (only available on products with reference ending in "/KUE"). This simple solution provides easy, effective and retrofittable flood and odour control to access chambers. It does not need to be specified at point of order, unlike nearly all flood and odour plate alternatives. Achieves compliance to Class 3 leak tightness performance in accordance with Table 1 of Section 2 within WIS 4-26-01 when fitted with no leak (/NL) sealing plate. 
A quality above the restUnite gully grates also availableOur premium Unite range also includes D400 gully grates. Unite gully grates offer a new way of thinking, with cutting edge design and are packed full of proven features. This package combines deliver a super long-life with the lowest whole-life cost of any D400 gully grate available today.
