Our MD, Warren, went speed dating this week.

Not THAT kind of speed dating, although he did come back to the office with a few numbers!

He went to Design Sessions: Architects & Interior Design, where he spent 10 minutes per architect, had lots of good conversations and made plenty of great matches. It’s exactly what you want from any kind of speed dating! He even ran into some of our current clients. Still going strong, we’re happy to report.

Thanks to everyone who stopped by the Newton Waterproofing booth at the event. Warren had some brilliant chats about getting waterproofing right at the design stage, before it becomes a problem on site.

If you need any waterproofing solutions, give us a ring and we’ll set up a date.

Last week, Richard spent an afternoon at WSP in the UK & Ireland London Chancery office delivering a CPD on Pumping Systems to a small team. We had some really good questions and our newest team member, Emily, was there to capture a bit of the session.

Thank you WSP London for welcoming us and we hope for more opportunities to work together on CPD sessions!

How do you seal submerged sheet piles in a harbour? Our latest case study in Yorkshire had to tackle this exact challenge, taking on a marine sheet pile waterproofing project in Scarborough.

Scarborough Harbour’s West Pier has faced decades of exposure from its harsh marine environment, causing corrosion, movement and distortion of the existing sheet piling.

As part of a structural strengthening programme, new sheet piles were fixed to the existing harbour wall. However, this created over 100 irregular voids between the old and new piling, with gaps ranging from 15–50mm.

Following extensive testing and collaboration between Neom Engineering, LCM Environmental and PM Diving Services, a bespoke polyurethane injection solution was developed using PC Leakinject UNI 6816 E resin from Tradecc.

The resin was injected underwater to seal the voids, joints and interlocks, while also filling the space beneath the sheet piling to create a stable, waterproof base.

Approximately 100 underwater repairs were successfully completed, helping to isolate the steel piling from seawater and oxygen and extending the operational lifespan of the structure.

A great example of collaborative engineering to overcome a complex marine waterproofing challenge!

We'll be keeping our fingers crossed as we head to the National Building & Construction Awards this Friday at the Leonardo Hotels Tower Bridge Hotel.

The Newton Cloud has been shortlisted in two categories:
🏆 Construction Software Award
🏆 Innovation of the Year

The Newton Cloud is our cloud-based pump monitoring system, providing real-time oversight, notifications and alarms for installed basement pumping systems.

Monitored data include pump activity, water levels in the drainage channels, alarm events, battery and inverter health, and live and historical system data.

The system provides early warnings of potential issues and enables remote monitoring, helping contractors and clients maintain greater oversight of their pumping systems. This also reduces the need for unnecessary site visits.

We’re proud to see the development and innovation behind The Newton Cloud recognised at the NBCA and look forward to celebrating with the other finalists this Friday!

Good luck to all the finalists in both categories, including:
> Buildscout
> Bailey Partnership
> GAP Group Careers
> The Guardtech Group

When concrete fails, speed and strength matter.

Rapid-set, high-strength repair mortars, such as HydroCoat 203-RM, are designed to restore structural integrity without slowing your project down.

Without the right solution, water ingress can lead to long-term damage, corrosion, and costly remediation.

What difference does HydroCoat 203-RM make?
✅ High bond strength exceeds tensile strength of concrete
✅ Dense matrix resists 10 bar water pressure
✅ Reliable strength development, even at sub-zero temperatures
✅ Incorporates the latest cement chemistry, fibre and styrene acrylic polymer technology

HydroCoat 203-RM offers exceptional performance as a rapid set mortar, delivering fast setting capabilities and rapid strength gain that makes it ideal for urgent repair work.

As a single component, requiring only the addition of water, the rapid-curing mortar has reliable strength development that is not significantly affected by low temperature use.

Concrete Repair Using Waterproof Mortars...

Concrete repair below ground involves more than simply restoring damaged areas. Where structures are exposed to water ingress, the repair material also needs to work as part of the overall waterproofing strategy.

Waterproof mortars can be used to repair areas of damaged concrete, including:
• Cracks and localised damage
• Voids and honeycombing
• Construction defects
• Damaged edges and corners

When specifying a repair mortar, factors such as water pressure, substrate condition, application area and compatibility with the existing concrete should all be considered.

Good preparation is also essential. Loose or deteriorated concrete and contaminants should be removed to provide a sound substrate and support the long-term performance of the repair.

For below-ground structures, understanding the cause of the defect and source of water ingress is key to selecting the right repair approach.

This prestigious new-build hotel in the South West is utilising HydroBond 403 to provide a durable waterproof barrier for the lifetime of the building.

HydroBond 403 is a high-performance, self-healing, composite sheet membrane with exceptional waterproofing capabilities. Fitted above the raft support or to wall formwork, the locking fleece is encapsulated into newly placed concrete.

The integral bond created with the concrete then prevents lateral water migration from tracking behind the membrane, and ensures long-term durability.

As shown in these photos from Senior Site Manager Dan, the membrane has been pre-applied to the formwork, ready for the concrete pour.
