A QUALITY ABOVE THE REST Unite™ E600 Manhole CoversUnite is available with a 10 year warranty*. Packed full of design features that combine to give Unite the longest life and lowest whole life cost of any E600 access cover available. Designed and manufactured to exceed BS EN 124 and Highways England’s Design Manual for Roads and bridges (DMRB) specification CD 534 v0.2.0. 
Unite E600 manhole covers provide increased strength to the cover and structure, as well as enlarged frame corners that help to dissipate loads. These features work together to ensure Unite E600 has minimal movement in the ground – increasing longevity. The increased flange area provides a bearing pressure under test load of no more than 2.1N/mm2, adding another level of consideration for road environment requirements advised by Highways England. The anti-slide feature helps to prevent movement or sliding within the frame and minimises seat wear, further increasing the life of the product. The Unite range as a whole offers the most mortar-sympathetic frame arrangement available, employing a textured flange, which utilises the mechanical properties of bedding mortar rather than just the adhesive characteristics. The flange edge is deliberately round profiled, eliminating crack induction in surrounding bedding materials. All of this combines to ensure the longest operational life of any UK double triangular chamber top. In fact, 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 within project documentation to reference Unite and Highway product ranges for ironwork installations. These documents provide clear guidance to support specification and product selection during project planning. Incorporating these clauses within specifications helps provide consistency in product selection and installation approach across projects involving ductile iron access covers and frames.
Unite 10 year warrantyWhen installed with either Wrekin UniPak® rapid-set 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 design and overwhelming success in the local authority and utilities sector, Unite is the proven choice for strength and longevity for highway ironwork installations.

> 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. 
Textured flange surfaceFit and forgetUnites flange surface provides a textured finish for bedding mortar to adhere to and the mortar holes allow for interlocking between both sides. This allows Unite to utilise the mechanical properties of bedding mortar, not just its adhesive characteristics. The built in a 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 mortar-sympathetic design features, allow Unite installations to stand the test of time in extreme environments. 
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 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. 
Universal beamA strength above the restOur high rigidity support beams, based on 'Universal Beam' technology, result in lower seat wear, longevity and lighter covers. Developed using 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. 
Only with WrekinRetrofittable antenna optionsUnite* and Highway access covers are the only ranges on the UK market to include provisions for communications equipment, such as antennas, to be installed within the cover. 
The ID bolt provision can be used for antennas, allowing communications equipment, such as water meter monitoring, to be installed within a chamber beneath a cover while providing a strong signal above ground without the need to dig or adjust the surrounding road surface. Saving time, effort and money while minimising disruption. * references ending /KUE Unite™ accessories
