Condensation and Vapour Pressure
So last time we talked about condensation and relative humidity, how this is expressed as a proportion of how much moisture air can hold at a given temperature, and how 'dew point' temperature, is the exact temperature where vapour condenses back into a liquid (100% RH).

Today let's think about vapour pressure. This is actual quantity of moisture in the air.
Simplistically therefore, high vapour pressure = wet air, low vapour pressure = dry air.
The thing to understand about differential vapour pressures, is that they will seek to equalise.
What does this mean? Example:
Two sealed rooms with a wall and door separating them. One has a shower in it which has been running and it's steamy/humid, i.e. high vapour pressure. The other room has a dehumidifier running and it's very dry / low vapour pressure.
When the door is opened between the rooms, what happens? Does each level of vapour stay exactly the same in each room?
No.
We provide a single point of responsibility protecting all stakeholders.
We take full accountability for the waterproofing process, serving as a single point of responsibility to ensure seamless coordination and execution. This approach protects all stakeholders by minimising risk, eliminating communication gaps, and ensuring the highest standards of quality and reliability throughout the project.
