There are a variety of reasons you want to waterproof your basement. The primary reason, being, of course, you do not want a waterlogged or flooded basement. Throughout the course of this brief article, you will learn of a few of the most common causes why your basement is waterlogged or leaking.
Plugged Drain Tile
Newer homes are usually constructed with a drain tile which wraps around the perimeter of your basement. It's a series of plastic pipes that are wrapped in a cloth "sock." This is then placed atop pea gravel and installed at the foot of the walls of your foundation. Although strong, this system is subject to damage. Tree roots can be particularly damaging to plugged drain tile. Damage to the drain tile can cause water to seep in through the foundation itself, essentially, which can cause water damage.
A top-of-the-wall leak occurs when moisture or rainwater from near the top of your foundation makes its way inside of your basement. This is particularly bad whenever the soil around the top of your foundation slopes towards the top of the foundation itself, essentially causing rainwater to "pour" into your home. Older homes are particularly susceptible to this type of leak due to the fact that the soil around the house tends to settle, over time, which can create rivets in the soil that allow water to run straight down into the foundation itself.
The point where your wall meets your flooring can be a place that is susceptible to leaks if the foundation was not poured entirely well. Even well-constructed foundations can become susceptible to these "joint" leaks. There is an area at the bottom of your foundation called a "keyway" – it is essentially two layers of concrete that allow your building some give. It is structurally effective, but occasionally will become subject to leaking due to the fact that there is a layer of air in between these two layers where air and moisture can become trapped. Joint leaks are quite difficult to fix, especially if they are caused by the presence of keyway.
