A bridge deck is a superstructure between two abutment walls that is often supported by central piers where the span extends a significant distance. Bridge decks can be supported by a traditional brick or stone barrel arch construction or pre-tensioned precast concrete units.
Traditional construction techniques involve waterproofing of the decks by spray applied liquid membranes such as Stirling Lloyd Eliminator or sheet membrane systems such as a Wolfin membrane systems.
The above systems are now considered costly and disruptive with elastomer gel injection systems from M C Building Chemicals being considered as a more modern approach to waterproofing of bridge decks as all work is carried out from below the deck with product being injected to form a flexible, continuous membrane without the need to lift track or road surfaces.
Hundreds of structures throughout Europe and in the UK have been waterproofed with the MC Building Chemicals elastomer gel injection system with great success.
