The watertightness describes the ability of a building construction or a seal (z. B. a compriband ), the rain water in rain to resist.
If a construction (e.g. a facade ) is additionally exposed to the wind , a back pressure builds up in front of this construction , which depends on the wind speed. This dynamic pressure also drives the rainwater through the seal, so that a driving rain resistance is given with a pressure in Pascal (Pa). A driving rain tightness of 600 Pa means, for example, that the rainwater does not penetrate through a joint seal even under a pressure difference of 600 Pa .
The watertightness is defined in EN 12208. This standard replaces the DIN standard DIN 18055.
