Precast waterproof concrete at Vauxhall Tunnel

The construction of a pedestrian tunnel beneath Vauxhall Bridge, using precast box culverts, required PUDLO as a high performance waterproofing and corrosion-resistant solution in order to meet the aggressive saline soil conditions in the Thames tideway. PUDLO was used in the casting process primarily as a waterproofing agent, but also as additional protection against the corrosive effects of the soil, as described in BRE Digest 363 Concrete and Concrete Products in Aggressive Ground.
