A common question people have when finishing a basement is.
Plastic lining basement walls and floor.
Air gap membranes a modern vapour proof barrier lining it is a dimpled plastic sheet fixed onto brick stone block or render with plastic plugs to form an air gap cavity.
Water vapor in the warmer air of your home begins to condense on the colder surface of the glass of water.
Think of a glass of ice water.
Waterproofing a basement with dirt walls and floors is very similar without the jackhammering.
Thats exactly how i was taught 20 years ago and still use that exact method hasnt failed ever.
Tape a one foot by one foot square of plastic sheeting plastic kitchen wrap will do to the concrete wall in your basement with duct tape and leave it in place for 24 hours.
Plastic will keep moisture from moving through the wall.
We ll still install a drain and sump pump along the perimeter.
However we also very strongly recommend installing a plastic vapor barrier on the walls and floors as moisture can easily pass through the dirt and create a humid space.
Then remove the tape.
Our crawl space wall liners are translucent and are designed to wrap easily around the length of the interior walls of your crawl space as well as around the piers.
If you place plastic it will trap the moisture in the wall cavity and you will have some serious issues.
If the ground is uneven smooth it with a tamper or a 2 by 4.
We also offer liner staples and christmas tree fasteners to help you attach your floor liners securely to your wall liner at the piers or to bora foam insulated boards.
Not a vapour barrier so damp and salts from the unventilated cavity can eventually reach the inner wall decorations.
As we mentioned earlier the basement is naturally humid because of its location below grade.
