Further more function has verified experimentally the importance of mortar Attributes in identifying the peak to which damp will increase in partitions.[forty five] BRE Digest 245 lists several elements which can influence the peak of the rise such as charge of evaporation through the wall, pore dimensions of your masonry, salt content of the components plus the soil, groundwater and diploma of saturation, and utilization of heating within the residence.[fourteen] The outcome of seasonal variations in evaporation level on the height of dampness increase are already comprehensively explained.[50]
Increasing damp can be determined by a attribute "tide mark" about the reduce portion of influenced walls. This tide mark is because of soluble salts (specially nitrates and chlorides) contained inside the groundwater.
