PROJECT SUMMARY: Structural Waterproofing
SDG are proud to be a supplier of structural waterproofing and concrete protection systems to London’s new Silvertown Tunnel. The Silvertown Tunnel will be a new 1.4-kilometre twin-lane road tunnel under the River Thames, linking North Greenwich and Silvertown.
The £2 billion infrastructure project will feature a dedicated lane for buses, coaches, and HGV’s, allowing for a significant increase in public transport capacity across the Thames.
THE CHALLENGE
With any piece of critical infrastructure, a significant life span is a key design element. As governments continually work to build tomorrow’s world, manufacturers such as Master Builders Solutions do their best to harness technological material advantages to prolong the life of these structures.
With the potential for indefinite exposure to challenging ground conditions, the selection of the right structural waterproofing solution and concrete protection system is critical.
