Deterioration of the previous concrete cable covers had resulted in water ingress. This was having ramifications with the Station’s fire protection system in the Turbine Hall Cable Tunnels.
To rectify the problem localised joints were filled with a fast setting mortar and the area was cleaned and prepared using a water jetting unit before a concrete was primer was applied. Sikalastic 625 was then applied.
Sikalastic 625 is a single component, cold-applied, moisture-triggered liquid waterproofing membrane that cures to form a seamless, durable and weather resistant waterproofing solution for exposed areas. This coating was selected for the work as it is completely cold applied so there is no requirement for any heat or naked flame. This meant the risk of fire was completely eliminated and work could be safely carried out whilst operations continued.
Visual inspections of the work since completion have confirmed that there is no further ingress despite heavy rainfall over recent weeks.
