Open balustrade – fixings through a waterproofing membrane

Cause

A high risk detail known to result in leaks 

Repair

  • remove screws, fill holes with sealant as an interim measure if it is not leaking. Consider redesigning the balustrade at the first major maintenance of the deck 
  • where it is suspected that the building may be leaking and there is a risk of damage, engage a building surveyor to report on the building and advise on repair options
