The control of moisture
There are four sources of #moisture associated with #foundations:
(1) surface water,
(2) soil moisture,
(3) groundwater, and
(4) construction materials moisture.
Surface #water from #rain and #snow-melt is controlled through the use of #eavestroughing and #grading.
Soil moisture, in the form of water or water #vapour, is controlled by #dampproofing materials and #drainage.
Where the #groundwater table is high enough to cause hydrostatic pressure against the foundation, it is controlled by #waterproofing combined with a structural design capable of resisting water pressures.
Construction moisture, principally water in concrete, is best controlled by allowing adequate #curing and drying time before enclosing.
