Flashback Friday – Tottenham Hale Underground Station.

12 months ago, Team Cemplas installed Sika 1 waterproof render and screed to the retaining walls and floors.

The waterproof render was applied to provide a secondary waterproof barrier onto, in-situ, reinforced watertight concrete. The movement joints incorporated a non-biodegradable Sikadur Combiflex hypalon strip to the movement joints to the new concrete fire exit staircase.
