The Repair of London’s Putney Bridge Made Easier – and Faster - by Metaset and the Eliminator

Bridges play a central role in any major city and region, especially when it comes to such a busy area as London.

However, the fact is that there are many bridges that need repair and refurbishment around the world and these bridges can definitely benefit from innovative solutions in order to get the upgrade they desperately need.

In India, for instance, a new production system’s hollow core slabs and panels are being used in the creation of bridges, with an additional system that is not only mobile, but is also capable of feeding itself.

But here on our own shores, we have also made use of improvements and innovations in bridge repair, beginning with southwest London’s busy Putney Bridge. The Putney Bridge repair and refurbishment project was estimated at around £1.5 million, and it made use of some of the most advanced waterproofing materials developed by Stirling Lloyd Polychem.

 

More about the repairs on Putney Bridge

Putney Bridge, as you may already know, is a Grade II bridge crossing the mighty Thames River that also has the distinction of being a listed monument. The problem with Putney Bridge is that it has suffered from extreme penetration of water which has resulted in a very poor pavement and road surface. When those involved in the project removed the existing asphalt surface of the bridge, it was found that the current waterproofing system (which was made from polyurethane) had already delaminated and de-bonded from the bridge’s substrate, resulting in leaking and an even poorer construction.

A waterproofing solution for this extensive damage was then proposed by Stirling Lloyd Polychem: the use of Metaset concrete, which is a fast-cure material used for the repair of damaged or destroyed areas and substrate. In addition to the Metaset concrete, the firm also recommended the use of its own Eliminator product and system, which provides more seamless waterproofing for the bridge’s deck.  

 

More on Metaset and the Eliminator

The Metaset concrete from Stirling Lloyd Polychem is known for being a multi-purpose product and material that is also extremely strong and durable. But what makes it even more remarkable is the fact that it can cure very quickly – in as little as two hours – even with very cold or very hot temperatures. The concrete has also been designed to accept any type of load in a matter of two to four hours.

Meanwhile, the Eliminator is a product which can easily be distinguished as well. It is actually a membrane for additional waterproofing that is comprised of a cold liquid which can be sprayed onto a bridge’s deck.

The Putney Bridge project was undertaken by several contractors, one of which was FM Conway, who was the main contractor for the existing waterproofing and surfacing work. Another contractor, Metrail, worked alongside FM Conway to undertake the bridge repairs and spray the waterproofing material.

 

As we all know, Putney Bridge is a major thoroughfare and access route across the Thames, so it was imperative that the project be finished as soon as possible. Regular commuters and even tourists go across the bridge every single day, so the use of Metaset and the Eliminator made a big difference. Thanks to these innovations, the disruption to motorists and other commuters was minimal. The final result is an improved bridge that can be thoroughly enjoyed by Londoners and visitors alike.
