When Water Enters the Timber Stud Frame of the External Wall, It Compromises Structural Performance
Answers to the Questions Raised in the Video Above:
The wall in this video is an external wall.
The significant water damage to the timber frame was caused by poor site conditions.
There was inadequate sloping around the property.
The concrete paving level was also too high, covering almost half of the weep holes.
As a result? Over time, water entered the wall frame…
Now, HOW can we prevent this from happening?
As a Structural Engineer, it’s critical to include proper detailing in your drawings.
This includes specifying ground slope away from the property and maintaining enough clearance between the bottom of the weep holes and the finished surface level.
As a Site Supervisor, it’s crucial to ensure these details are currently implemented on site.
That means checking concrete paving levels, verifying surface drainage, and ensuring the work matches the design intent and specifications.
And as a Tradesperson, it's essential to follow those instructions accurately.
Cutting corners, even slightly, can lead to major structural and maintenance issues later on.
Each role plays a part in preventing water ingress.
And when we all take responsibility, we protect the structure, and the people living in it.
