Manhole covers PulsePulse is built around an inverted T-flange frame† that improves bedding stability, protects the chamber and prevents the stress concentrations that lead to cracking or early-life failure. Available in both D400 and E600 load classes, it has been validated through one of our most extensive client-led testing programmes, including mortar stress evaluation, impact testing and full-scale field trials beyond the requirements of BS EN 124-2. By maintaining long-term structural integrity and reducing reinstatement frequency, Pulse helps lower whole-life costs and embodied carbon, with verified Environmental Product Declarations supporting clear, measurable sustainability benefits for asset owners. 
Performance verified beyond the standardPulse’s design has been validated beyond the standard. Through a programme of laboratory and full-scale trials, including stress analysis and impact testing, Pulse demonstrated clear performance advantages over traditional welded-frame systems. The results speak for themselves.
Pulse 7-year warrantyWhen installed with either Wrekin UniPak® rapid-set polymer resin bedding mortar, or flowable, CD 534 compliant bedding mortar, the Pulse range is available with a 7-year product warranty*. Due to its unique design and overwhelming success in the local authority and utilities sector, Pulse is the proven choice for durability and longevity for highway ironwork installations.

Strength without compromiseCarriageway ironwork is exposed to relentless punishment from wheel-line loading, braking forces and turning movements. Over time, these forces create fatigue that can damage both the frame and the bedding beneath. Traditional welded large frames struggle under this type of repetitive loading because weld points become natural stress concentrators. Once these points begin to crack or distort, the bedding starts to break down, the cover begins to rock and costly reinstatements quickly follow. Our largest Pulse units (Carriageway 2 and Carriageway 3) eliminate this weakness entirely. Each frame is cast as a single, continuous, non-welded structure, removing the vulnerable joints found in older designs. This gives the frame far greater structural integrity, allowing traffic loads to be transferred more evenly into the bedding mortar and reducing the risk of localised stress that can damage chamber walls or cause the bedding to fail prematurely. These design decisions aren’t theoretical. Independent testing confirmed up to 78% reduction in peak bedding stress when compared with competing welded-frame designs, along with a 13% reduction in overall deflection. Lower stress and reduced movement mean the bedding performs better for longer, maintaining a stable, rock-free installation under repeated trafficking. The result is a more robust, reliable solution that protects the chamber, preserves the bedding and significantly extends service life. By reducing maintenance interventions and the carbon associated with repeat reinstatements, Pulse helps asset owners create safer, more resilient and more sustainable networks. 
Designed for utilitiesTailored to the water, telecoms and energy networksEvery detail of Pulse has been developed with the unique needs of UK utility networks in mind. Designed specifically for telecoms, water and energy chambers, it delivers the strength, stability and reliability these critical networks demand. We work closely with leading network operators, including Openreach, Thames Water, Vodafone, Severn Trent, United Utilities and UK Power Networks. We’ve developed Pulse around real installation practices and performance expectations. By protecting chamber walls and bedding materials from stress and deformation, Pulse maintains network integrity and reduces the likelihood of costly reinstatements. For asset owners and contractors, this means a solution that not only meets specification and compliance standards, but also supports operational efficiency. Pulse reduces whole-life cost, lowers maintenance frequency and provides the long-term resilience that modern infrastructure networks depend on. 
Engineered to protect the chamber and the bedding beneathInverted T-flange frame for balanced, long-term stabilityAt the core of Pulse’s performance is its inverted T-flange frame, a new generation of frame design developed through extensive finite-element analysis, field trials and live-traffic evaluations across UK networks. The profile provides continuous support around the frame edge, reducing deflection and distributing loads evenly around the whole frame into the bedding mortar and chamber structure. This geometry balances stresses across the frame. Preventing the outer edge lifting that can crack bedding mortar and the inner edge drop that can damage chamber walls. Independent testing confirmed up to 78% reduction in peak bedding stress and around 13% less deflection compared with welded-frame designs. †Only available on Carriageway 2 and 3 variants. 
Strength and stability where it’s needed mostI-beam reinforced covers for superior rigidityThe Pulse cover structure features universal beam reinforcement (otherwise known as I-beams). Engineered to deliver exceptional rigidity and stability under repeated wheel loading. This design strengthens the cover without unnecessary weight, helping it resist flexing and seat wear that can develop over time. By controlling deflection, the I-beam structure ensures consistent load transfer between the cover and frame, maintaining a rock-free seating and reducing long-term fatigue. The result is a robust, stable assembly that protects the integrity of the chamber below and extends service life, even in the most demanding carriageway environments. 
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 significant time, effort and money while minimising disruption. * references ending /KUE Pulse gallery
