The best waterproofing system on paper still has to be practical to install on the structure.

That becomes particularly important on existing rail bridges, where access can influence how the work is approached.

The location of the water ingress, the areas of the structure that can be reached and the way the waterproofing system needs to be installed all have to be considered before deciding on the methodology.

TSM delivers specialist waterproofing across bridge and rail infrastructure, with different systems available depending on the structure and the problem being addressed.

We are also continuing to develop our rail waterproofing capability through further system-specific training.

Because on an existing bridge, specifying how to stop the water is only part of the job.
You also need a practical way to get the system where it needs to go.

A brilliant evening at Vintners’ Hall in London, where James Jannetta and Rory Dawson CSSW joined Delta Membrane Systems Ltd for their Innovation Evening.

With so many people from across the waterproofing industry in the room, it was a great opportunity to catch up with familiar faces and meet others working in the sector.

Thank you to everyone at Delta for the invitation and hospitality. James and Rory thoroughly enjoyed being part of it!

“Can you get someone to site tomorrow?”

It is a call we receive fairly regularly when significant water ingress appears on a live project.

By that point, the problem can be affecting far more than the structure itself. Other works may be unable to continue, with teams waiting for the water to be brought under control before they can progress.

That puts a very different pressure on the repair.

TSM’s resin injection teams can mobilise at short notice to investigate the water ingress, establish the route it is taking and carry out the remediation needed to get the area back under control.

We’ve had projects where the call comes in one day and the team is on site the next.

In those situations, every day spent waiting for a specialist response can become another day lost elsewhere on the project. This is why we always have the materials available and we ensure we can be flexible to support a clients delivery.

A look at TSM in action.

From specialist structural repairs to leak sealing and working on complex infrastructure projects, our teams are out on site every day delivering the work that keeps existing structures in service.

Here's a glimpse of what that looks like on the ground.

Being a specialist contractor doesn't mean specialising in one thing.

TSM works across concrete repair, structural waterproofing and a range of specialist maintenance disciplines, often across very different infrastructure environments.

What connects that work isn't a single product or service.

It is the type of problem we are brought in to solve.

Our teams are usually working with existing structures where something has deteriorated, failed or needs protecting, and where the solution requires knowledge that sits outside general construction.

That could mean understanding why water is moving through a structure, dealing with deterioration within reinforced concrete or installing a specialist system with very particular performance requirements.

As TSM has grown, we've added different areas of expertise around that core purpose.
So when we describe ourselves as a specialist contractor, we're not describing one specialism.

We're describing the work.

Wastewater structures are not only exposed to chemicals. In some areas, they also have to withstand constant physical wear.

Flowing wastewater can carry grit, solids and debris through assets such as screening channels, wet wells and inlet chambers.

Over time, that movement can wear away vulnerable surfaces and reduce the protection provided to the structure beneath.

That is why abrasion-resistance can be an important part of the specification for recycled water infrastructure.

TSM delivers repair and protective systems for these environments, including abrasion-resistant coatings where the operating conditions demand them.

In wastewater assets, the material has to cope with more than what is in the water.
It also has to cope with what the water is carrying.

Within manholes, chambers and other wastewater assets, hydrogen sulphide (H₂S) can be generated as part of the process.

In moist, oxygenated areas above the wastewater level, bacteria can convert H₂S into sulphuric acid. Over time, this attacks cement-based materials, the result can be progressive surface loss and softening of the concrete, exposing the aggregate and, in more advanced cases, the reinforcement beneath.

TSM installs specialist H₂S-resistant lining systems to protect wastewater structures against this type of chemical attack.

Applied to repaired or existing concrete, the lining creates a protective barrier between the substrate and the aggressive environment within the asset, helping prevent further deterioration and extend its service life.

With wastewater assets, understanding what is causing the deterioration is just as important as repairing the damage.

Two fantastic additions to our Clean Water team 👏

Please join us in welcoming Jamie Hislop and Jay Stewart to Total Specialist Maintenance, both joining our rapidly growing Clean Water division.

Jamie joins us as Framework Manager, taking a leading role in the continued development and delivery of our clean water frameworks, while Jay joins as Works Manager, overseeing the safe and successful delivery of our projects on site.

Both Jamie and Jay bring with them significant experience within the water industry, a wealth of technical and operational knowledge, and an excellent understanding of delivering works across major clean water frameworks.

These are two really important appointments for TSM and another big step in strengthening the team as our presence within the water sector continues to grow.

We’ve worked incredibly hard to build our Clean Water division, and attracting people of Jamie and Jay’s calibre and experience says a lot about where the business is heading.

We’re absolutely delighted to have them both on board and really looking forward to seeing what they bring to the next stage of our growth.
Welcome to TSM, Jamie & Jay! 🧡🖤

A deteriorated culvert does not always need to be excavated and replaced.

Depending on its condition, the existing structure may be suitable for targeted repair and waterproofing, extending its service life without the disruption associated with full replacement.

TSM carries out specialist repairs to existing culvert structures, including concrete repairs, crack and leak sealing, resin injection and waterproofing.

The approach will depend on the cause and extent of the deterioration, whether that's water ingress, cracking, defective joints or deterioration of the concrete itself.

Where access and excavation can be difficult, repairing and protecting the existing structure can provide a much more practical solution.

For buried infrastructure, understanding what can be retained and repaired should always come before assuming it needs to be replaced.

A stronger repair material does not automatically make for a better masonry repair.

Older brickwork and masonry structures can behave very differently from modern construction, particularly in the way they accommodate moisture and movement.

Introducing a material that is harder or less permeable than the original can change that behaviour.

Rather than improving the repair, it can transfer stress or trap moisture within the surrounding masonry.

This is why material compatibility is such an important consideration when repairing older structures.

TSM carries out specialist brickwork and masonry repairs across heritage and infrastructure assets, including the use of lime mortars and matched replacement brickwork where required.

With masonry, the strongest material is not necessarily the right one.
The right material is the one that works with the structure already there.
