Question 2

What are the pros and cons of liquid applied systems?

Answer 2

Pros:
* Seamless
* Installed to full profile
* Works well with intricate shapes

Cons:
* Substrate needs to be clean/dry (weather dependent).
* Cannot be applied over previous systems
* Requires high quality workmanship
* Subject to building stress

Question 3

What are the pros and cons of bonded membranes?

Answer 3

Pros:
* Seamless
* Installed to full profile
* Can increase capacity

Cons:
* Substrate needs to be clean/dry (weather dependent)

* Complex outlets (syphonics) ignored

Question 4

What are the pros and cons of a fold out system?

Answer 4

Pros:
* Components (outlets, corners etc) are factory formed
* The membrane can be extended

* Sole boards need to be installed to remove height of bolts, reducing gutter capacity
* Design limited
* Weather dependent install

Question 5

Answer 5

Pros:
* Seamless
* Installed to full profile
* Can increase capacity
* Components (outlets, corners etc) are factory formed
* Less prep work required
* Less weather dependent

Cons:
* Thermal movement considerations required.
* Building movement and lining movement may cause ponding.
