Waterproofing Lightwell N1

Details

Delta Registered Installers, Renderseal Ltd were called upon to provide a waterproofing solution to an extremely narrow lightwell to a medical facility in North London.

The scope of the project was to facilitate a solution for a damp, salt and mould covered lightwell wall, which was impacting negatively on staff who thought their office views were unsightly and unhygienic.

After many years of the medical facility seeking to remedy the problem by repainting the wall, continuous maintenance issues due to water staining, salt patches and algae growth lingered. A lightwell (also known as a light well or air shaft) is an architectural feature which allows natural light to enter an interior space of a building and can also promote good ventilation in areas which would otherwise require artificial light or have poor ventilation.

A lightwell can take form as a vertical shaft within the volume of a building that typically penetrates from roof level down to lower levels. Lightwells can be an open space or with a roof making it an enclosed space. Lightwells can be problematic if they are not drained correctly.
