Foundation wall waterproofing is an important step when the walls are being installed -- I work in construction and remodeling, and I can't tell you how many homes I've seen suffer from shoddy foundation wall waterproofing. Since the article doesn’t mention that, I’ll explain a little bit. Like the article states, concrete is the most common material used in making foundation walls.
It’s great for this because it’s sturdy and can bear loads easily. It creates a robust foundation for any house. However, it’s porous and absorbs moisture from the ground. It can also absorb moisture from the surrounding air if the house is built in a really humid area. Over time, the concrete’s collection and release of water can erode away the soil underneath the house’s foundation. That can cause major problems and expensive structural damage.
The best way to prevent this type of catastrophe is to treat the concrete foundation walls with a waterproof coating. Coatings are easy to apply. Simply spread a thick coat onto the foundation wall, let dry, and then continue with your construction project. It’s a small step that can help prevent huge problems down the line.
