Groundwater not only rises through capillaries in walls it can also rise up in concrete floors. Capillary penetration of fluid from the ground up through concrete or masonry is known as rising damp and is governed by the shape and porosity of the construction materials through which this evaporation limited capillary penetration takes place.

Rising damp is widely misdiagnosed in existing buildings based on the incorrect interpretation of visual evidence and the readings of moisture meters. Mix the cement based mortar with water to make a slurry and use a plastic heavy duty injection gun to inject this into.
