VAPOR RETARDER. A vapor-resistant material, membrane or covering such as foil, plastic sheeting or insulation facing having a permeance rating of 1 perm (5.7 ´ 10-11 kg/Pa × s × m2) or less, when tested in accordance with the dessicant method using Procedure A of ASTM E 96. Vapor retarders limit the amount of moisture vapor that passes through a material or wall assembly
Vapor barrier is commonly used in the basement on the outside of the wall to keep the ground moisture out of the wall materials. If the wall is existing, and earth is against the outside of the wall, it is not uncommon to apply a retarder to the inside of the wall prior to adding insulation or finish materials.
In cold areas vapor barrier is applied to the wall on the WARM SIDE IN WINTER over the insulation to keep moisture from getting to the insulation and condensing as the air gets colder on the outside of the wall. The building codes actually require this application in most areas.
Hope this helps!

The best insulation to use is spray foam, although it is an expensive option. Another option that is less expensive is 1" rigid foam board. Both of these options eliminate the need for tar paper or a vapour barrier as they are self-sealing applications. Avoid using batt insulation w/vapor barrier in basement applications as condensation may occur which will encourage mould growth.

What is basement waterproofing?
Basement waterproofing refers to the process of making a basement or cellar water-resistant. It involves various techniques and methods that are used to prevent water from penetrating into the basement and causing damage to the foundation and walls of the building. Some of the common methods of basement waterproofing include installing a sump pump, sealing cracks and gaps in the walls and floor, installing drainage systems, and applying waterproof coatings or membranes. These methods are designed to redirect or prevent the entry of water into the basement and protect the structure from water damage. Basement waterproofing is important because water damage can lead to structural problems, mold growth, and other health hazards. By preventing water from entering the basement, homeowners can ensure that their property remains safe and secure.

Why is a cool basement often damp in the summer?
In a basement, the earth itself (and sometimes bedrock or large boulders) prevent extreme temperature extremes from occurring. In the summer, the basement would then be relatively cool compared to the outside temperature. Also in summer where people have basements, it gets humid as well as warm. When this humidity gets into the basement, some of the moisture in the air condenses out onto cool surfaces. This results in a general dampness in a basement. And, this dampness can become a kind of mustiness, since many basements have poor ventilation to circulate fresh air through them.
