Crane Mats Across Global Project Types: How Ground Protection Needs Vary by Sector

Energy infrastructure - and nuclear new-build above all - sits at the demanding end of the spectrum, for a specific combination of reasons. The plant is often exceptionally heavy: reactor components, pressure vessels and structural steel modules push crane classes and outrigger loadings well beyond anything a typical commercial build generates. The sign-off culture is just as heavy - temporary works, ground protection included, go through detailed design scrutiny before anything is accepted for use, and there's little appetite for undocumented assumptions about ground bearing capacity. And the programmes run for years, not months, which means ground protection isn't a short-term convenience but infrastructure that has to perform lift after lift for the life of the works.

We've supplied ALIMATS to Hinkley Point C, the UK's nuclear new-build programme in Somerset - exceptionally heavy plant, high scrutiny and a multi-year programme in one place. It's exactly the combination this category throws at the ground.

Transport infrastructure imposes a different set of constraints again. Rail work in particular happens inside tight, linear corridors - narrow strips of land bounded by live track, existing structures or third-party boundaries - which leaves almost no room to reposition a crane if the first ground assessment turns out to be wrong. Much of it also has to fit around the operational railway: possessions, curfews and engineering windows that compress the available working time into short, tightly scheduled bursts, often overnight or at weekends. Add the public visibility of a major rail scheme and there's very little tolerance for a lift that stalls because the ground protection wasn't ready, or wasn't up to the job.

We've supplied ALIMATS to both HS2 and the works at London Bridge - a new-build high-speed corridor on one hand, construction in and around one of the busiest working stations in the country on the other. Two ends of the same category, and both demanding for the same underlying reason: no slack in the schedule and nowhere to move the crane.

Airports stack another layer of constraint on top of the access and security considerations already common to major infrastructure. Construction happens close to live runways, taxiways and aircraft stands, inside a security environment that goes well beyond a normal site's access control. Terminal operations don't stop for a building programme - passengers, staff and aircraft keep moving throughout - so ground protection has to be reliable enough that a crane position never becomes an unplanned source of delay or disruption to a live airport.

We've delivered ALIMATS to both Heathrow and Gatwick - major hub airports where the build proceeds alongside continuous live operations, and where a ground-protection failure isn't a private inconvenience but a very public one.

Refineries and comparable process plants bring their own distinct constraints. Much of the site sits within classified hazardous areas, which governs what equipment, vehicles and working methods are permitted, and where. Continuity matters just as much - a live process plant often can't simply be shut down to suit construction or maintenance, so temporary works, ground protection included, have to be planned, delivered and installed around a running facility rather than a cleared greenfield. That also puts a premium on fast, responsive supply: a plant that identifies a ground-protection need mid-programme usually needs it solved in hours, not weeks.

We've supplied ALIMATS to Grangemouth Refinery in Scotland - and it's the site behind one of our sharpest delivery examples. An order placed with Ainscough Crane Hire in the early afternoon was on site the following morning, inside an 18-hour turnaround. That's what responsive delivery into a live industrial site actually looks like.

Wind farm developments are a different challenge again - one rooted less in scrutiny or operational continuity and more in geography. These sites are remote by definition: upland, rural, away from established road and utility networks, which means access itself is often the first hurdle before a crane ever gets near a turbine base. Ground conditions are frequently more variable and less predictable than a city site - peat, upland soils and undeveloped ground behave very differently from the made ground and engineered fill of a brownfield build - and there's usually far less existing site infrastructure to fall back on if the first plan doesn't hold. On terrain like that, a mat you can position without heavy plant is a genuine advantage.

We've supplied ALIMATS to major Scottish wind farm developments. It's a useful example precisely because it turns on terrain and access rather than plant weight or regulatory scrutiny - a reminder that the ground-protection problem doesn't scale neatly with how prestigious or technically complex a project happens to look.

Between those major infrastructure categories sits a much broader band of commercial, venue and residential work - and it earns its own heading precisely because of how much it varies in scale while the underlying logic stays put. At the large end, Manchester's Co-op Live Arena is a nationally significant venue build with substantial crane activity on a constrained urban site, and we've supplied ALIMATS there. Google's UK headquarters at King's Cross sits in the same bracket - a major commercial development in a dense, high-value location where getting ground protection right first time matters both for the programme and for the public realm around it.

At the other end of the same category, we've put ALIMATS on a residential build featured on a well-known national homebuilding television series - a single plot rather than a multi-hectare development. The scale is a world apart, but the question is identical to the one facing Co-op Live or a nuclear new-build: what's the actual load going into the ground, and has that ground been properly assessed to carry it. Scale changes the numbers. It doesn't change the question.

Ports, marine terminals and heavy extractive sites generate as much crane mat and ground-protection demand as anything above. Quaysides, laydown areas and processing sites all put heavy plant onto ground that regularly needs engineered protection - for exactly the reasons that run through this whole guide. The load has to be spread, the ground has to be assessed, and the two have to be reconciled before the lift ever happens. The engineering doesn't change at the water's edge or the pit head; only the surroundings do, and the same load spread and load transfer principles that govern a nuclear site govern a quayside just as firmly.

Strip away the sector-specific detail - the sign-off culture of a nuclear site, the possession windows of a rail corridor, the hazardous-area rules of a refinery, the remoteness of a wind farm - and the same question sits beneath every one of them: what is the actual load, what is the actual ground, and has that combination been properly assessed rather than assumed. That's the whole of load spread and ground bearing capacity, which is why we've given each its own companion guide - Load Spread Calculation and Ground Bearing Capacity Explained - rather than repeat them here.

What changes from sector to sector is everything around that core: how much scrutiny the answer has to survive, how tight the site is, how much time there is to get it right, and how visible the consequences of getting it wrong will be. Working out which of those pressures applies to your project is, in practice, at least as useful a starting point as knowing which country it's in.
