Starting a full basement renovation in March in Edmonton, Alberta means snow and cold (it hit -40 degrees Celsius last week!) So to address the issue of moisture entering the basement through the concrete walls, we had to work from the inside first and leave the exterior drainage upgrades for later in the spring.

Applying waterproof foundation coating to the interior of the bare concrete walls will keep out moisture and prevent mould. We used a brush to apply the foundation coating rather than a spray application to minimize the amount of foundation coating becoming airborne.
