Rotary kilns are large, complex assets — and inspecting them thoroughly via rope access and/or scaffold is a challenge most operators know well.

Sutro Group was recently on site at Cemex UK, deploying the HausBots HB3 climbing crawler robot to carry out ultrasonic thickness testing on a rotary kiln. The robot climbed the vertical surface of the asset directly, collecting wall thickness data without the need for scaffolding or elevated access platforms, reducing shutdown time and eliminating working at height.

It's a good example of what robotic inspection makes possible — getting decision-grade data from assets that would previously have required significantly more time, cost, and disruption to access.

If you have assets where access is the barrier to proper inspection, reach out to our team to discuss how we can reduce your downtime and disruption to operations.

Water infrastructure in the UK is ageing. Around 60% of water mains were built before 1981 — and the inspection methods used to manage them need to keep pace with what that infrastructure actually demands.

At Sutro Group, we work directly alongside water utility teams to detect the failure modes that standard visual surveys miss: corrosion beneath pipe supports, structural deterioration inside confined tanks, and wall loss in in-service pipework. UAV, rope access, advanced NDT, and underwater robotics — deployed as a single coordinated programme, not separate contracts.

If your inspection programme relies on visual surveys alone, there's a good chance the most critical threats are going undetected.

The HSE's recent findings on RPE failures are a timely reminder that having the right equipment available is not the same as having the right controls in place.

At Sutro Group, respiratory protection is one part of a broader approach to working safely in hazardous environments. Our teams regularly work in confined spaces, at height, and in environments with exposure risks — including our current deployment at Vale, carrying out inspection work on a Volat kiln.

ISO 45001 accreditation underpins our approach — but accreditation alone doesn't keep people safe. It's the daily discipline of correct PPE selection, fit-testing, maintenance, and consistent use that does. Every time, without exception.

If you're reviewing your inspection contractor's health and safety standards, we'd welcome the conversation.

We're pleased to confirm that Sutro Group has successfully upheld three SGS ISO certifications:

✅ ISO 9001 — Quality management systems ensuring consistent service delivery

✅ ISO 14001 — Environmental management and sustainable operations

✅ ISO 45001 — Occupational health and safety management systems

They're the assurance that every inspection we deliver — whether rope access, UAV, NDT, or robotic — meets a consistent standard of quality, safety, and environmental responsibility.

In sectors where the consequences of getting it wrong are significant, that assurance matters.

Thank you to our teams for their consistent and unwavering dedication to our values in achieving this.

Inspecting water infrastructure means getting to places most teams can't.

Submerged tank walls that haven't been seen since commissioning. Confined underground networks where standard UAV technology simply won't operate. Elevated structures that would otherwise mean scaffolding, cost, and delay.

Sutro Group provides integrated inspection services for water utilities across the UK. Our capability covers the full range of access and assessment challenges — IRATA-certified rope access, UAV inspection including the Elios 3 for GPS-denied confined spaces, advanced NDT for subsurface corrosion detection and mapping, and underwater robotics for in-service tank inspection without dewatering.

If you're looking to get ahead of hidden deterioration rather than respond to failure, contact our team today:

Working in industrial inspection means health and safety isn't just a policy — it's a daily operational reality.

The sectors we work in carry genuine risk. Height, confined spaces, hazardous atmospheres, and complex plant environments are standard features of the job. Managing that risk well is what allows our clients to maintain their assets and our people to go home safely.

That means pre-task planning done properly, a team culture where raising a concern is normal, and using technology to remove people from harm wherever it's practical to do so.

Safety procedures exist for good reason. At Sutro, they're embedded into how we work — not a checklist, but second nature.

Sutro Group is supporting No Falls Week 2026 — a campaign by the No Falls Foundation to reduce workplace falls from height across the UK.

Here's why it matters to us.

In Great Britain in 2024/25 alone: 35 people lost their lives in falls from height. Up to 44,000 were injured. Over the last decade, falls from height have cost Great Britain more than £764 million and 416,000 lost working days.

Falls from height remain the single biggest cause of workplace fatalities in the UK. Behind every one of those numbers is a person, a family, and a team.

At Sutro Group, working at height is part of our daily reality — on water treatment sites, industrial plant, power infrastructure, and more. It's why IRATA-certified rope access, rigorous pre-task planning, and a team culture built around raising concerns aren't optional extras. They're the baseline.

If you work at height — or procure services from those who do — this week is a good moment to ask whether the right standards are in place.

A question we get asked fairly regularly is: should we be using drones or rope access for this inspection?

The honest answer is that it depends on the asset, the data you need, and what you're planning to do with it. Neither is universally better.

🚁 Drones are faster for wide-area visual survey, are excellent for elevated or difficult-to-reach structures, and remove personnel from hazardous areas. Where you need high-resolution visual data across a large structure in a short window, UAV is usually the right call.

🧗‍♂️ Rope access comes into its own where you need hands-on intervention — NDT techniques that require direct surface contact, repairs, or detailed inspection of specific weld locations. It's also the right choice in GPS-denied or electromagnetically challenging environments where drone operation becomes unreliable.

In practice, many of our projects use both.

The Elios 3 provides the initial survey and access intelligence; rope access technicians follow up on the areas that require closer attention.

Our UAV and rope access teams work together as a single integrated operation. That's not common in this industry, and it's one of the things that makes a genuine difference to how efficiently a project gets done.

Have a project where you're unsure which approach fits? Get in touch and we'll work out the best solution for your inspection.

Corrosion under pipe supports (CUPS) is one of the most severe — and most consistently underinspected — threats to pipeline integrity across industrial facilities.

The problem is straightforward: where a pipe rests on a support, moisture becomes trapped. Over time, corrosion develops in the contact zone, hidden from routine visual inspection. By the time it's visible externally, corrosion can already be significant.

Standard inspection methods often miss it entirely. Detecting CUPS accurately requires either lifting the pipe — costly and disruptive — or using inspection technology capable of assessing wall thickness without physical access to the contact area.

At Sutro Group, we work with HOMC (Higher-Order Mode Cluster) technology to detect CUPS without removing the pipe from its supports. It's non-invasive, accurate, and deployable across a wide range of pipe diameters and support configurations.

If hidden corrosion in your pipework is a concern — or if you're not sure whether it could be — we're happy to discuss your assets.

Rope access gets used as a catch-all term, but there's a significant difference between having operatives who can abseil and having a fully IRATA-certified team.

IRATA certification means every technician has been independently assessed to a recognised international standard — not just trained in-house. It covers technical rope work, rescue procedures, and safe working at height across the full range of industrial environments.

For clients in oil and gas, power generation, and water utilities, that distinction matters. It affects your liability, your insurers, and ultimately whether the job is done safely and compliantly.
At Sutro Group, all our rope access operations are IRATA-certified. It's the baseline we work to, not a selling point we wheel out.

If you're procuring rope access services and want to understand what you should be asking suppliers, feel free to get in touch.
