Waterproofing Solutions for Exterior Walls
Exterior walls are constantly exposed to moisture from rain, snow, and humidity. While some moisture is acceptable, excessive moisture can lead to serious problems such as mold, mildew, and structural damage. There are several ways to address exterior wall moisture issues like installing a proper drainage system, repairing cracks and gaps, and applying a waterproofing coating or membrane.
How Much Moisture is Acceptable in Walls?
The ideal moisture content for exterior walls is below 15%. If the moisture content exceeds 20%, it is considered excessive and can cause damage. You can measure the moisture content of your walls using a moisture meter.
