CANARY WHARF

Project Summary

MPS Concrete Solutions was engaged to resolve persistent water ingress issues at a high-end residential property in Canary Wharf, London. The structure, located below ground level, had ongoing leaks that posed a risk to both the building's fabric and internal finishes. Our client required a fast, non-invasive waterproofing system that would restore integrity without major disruption to the surrounding environment.

Construction of a bridge connecting London's Montgomery Street and Wood Wharf was a tricky project, so close to the Jubilee Line exclusion zone. MPS was on hand to keep things watertight.

The Challenge

This job called for a number of techniques working in perfect harmony to secure the abutments of this bascule bridge. Iron cylinders set into the riverbed supported pre-cast concrete boxes housing the mechanics, but water quickly found its way between the concrete and cylinders.

Waterproofing a structure partially submerged in the Thames called for close attention to health and safety, not to mention the right tools and expertise.

The MPS Solution

We installed a hydrophilic resin injection system to combat active water ingress through the basement slab and wall joints. The resin expands on contact with moisture, effectively sealing the paths of ingress and forming a permanent waterproof barrier. Using specialist injection equipment, our operatives delivered the system with pinpoint accuracy — all carried out from the interior, avoiding excavation or external disruption. The project was completed on time and with minimal disturbance to the building's occupants.

Injecting fast-setting hydrophilic resin, we secured the beams supporting both pits. Then we took care of the concrete joints and secured any cracks which had begun to form.

Not only were other teams relying on us to work quickly to keep the project on schedule, water was initially coming in so fast that our team started out working in tandem with the pumps to get the job done in record time.

The project was a resounding success. In fact, it won the Construction News Specialist Award for Project of the Year.
