________
PRINCIPLE OF WATERPROOFING
Tightness is defined as the resistance to possible passages of gas or liquid flows.
To check this seal, we check for leaks.
The presence of leaks is characterized by the passage of a gaseous or liquid fluid through a material. This leak is generally due to a material defect in the form of micro-cracks.
A gas or liquid leak is detected by showing the flow of a fluid passing through the wall during the test.
THE CHOICE OF GAS
The choice of gases used in testing will depend on the size and precision of the leaks.
- For fine and precise leaks, we use tracer gases such as Helium or Hydrogen which are gases present in tiny quantities in the air.
- For larger leaks, we use air pressure differential or air under water.
