A quality above the rest Unite™ D400 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 D400 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. 
Over the course of 40 years we have a deep understanding of pavement and highway ironwork performance. Using the very latest tools and software, the Unite range of manhole covers have been engineered for extremely long life. 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 cover flexing which may take place. We're so confident in Unite's performance, it's available with a 10 year warranty. Unite has been made to work sympathetically with bedding mortars, reducing stresses on the frame foundation, which has been identified by WRC as a major cause of manhole cover failure. 
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.

Mortar ‘gripper’ systemEffectively interlocked with bedding materialUnites 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 built-in 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. 
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. 
Locking bolt provisionProvide controlled accessOur Unite range can improve site security and provide security from theft and malicious damage or unauthorised access, with the addition of a factory-fitted locking bolt. In order to provide controlled access, Unite access covers can be supplied with factory-fitted screw fasteners. A specifically formed recess is provided for this purpose. 
Built to respond to flood riskSealAble compatibleSurface water entering foul-only networks is a hidden but significant issue. Even shallow ponding over a standard manhole cover can introduce flows large enough to overwhelm pumping stations and increase unnecessary treatment. 
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
