The control of moisture
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.

The Control of Moisture
The Control of Moisture
The control of #moisture transfer through #foundations is needed to prevent damage to the interior finish material and #basement contents, and to protect the long-term integrity of the #building structure. The measures that are used to control moisture transfer through foundation walls are also intended to control indoor #humidity levels and contribute to the reduction of soil gas and #radon entry into #basements, thereby contributing to a healthy interior environment.
