Introduction

The water absorption coefficient w is used for measuring at which rate a building material absorbs water:

W = amount of water [kg/m²], t = time in [h]

The water absorption coefficient indicates, how many kg of water per hour one square meter of material absorbs through capillary action.


The water absorption coefficient is used to measure the rate of moisture absorption of building materials.

Most common is the following classification of the water absorption coefficient (in kg/(m2*h0.5))[1][2]:

Please double check!!!*water absorbent (w > 2)

  • water inhibiting (w < 2)
  • water repellent (w < 0.5)
  • waterproof (w < 0.001)
