Are waterproof defects common?
Waterproofing of wet areas is one of the most common building defects reported! This is due in part to the wide variety of quality found among builders. The most common cause of waterproof failure is poor installation.
What do you check?
Waterproofing systems should resist:
- Differential movement
- Exposure to cleaning materials and alkalis from cement mortar
- Accommodate expected movement along substrate movement joints
It may not be the first report you think of when building or buying a new home but it is an area with many possible issues and defects. Let Fred Graham help you to avoid costly defects.
