They don’t come often, maybe once or twice a year, but you’ve likely experienced one of these storms with heavy rain that comes down fast. But for those who don’t know how to prepare their home for a storm such as these, it can lead to trouble in their basement when that water starts finding a way inside.

Exterior Basement Waterproofing

Maybe you’ve noticed some water seeping out from along the edges of your basement. Or maybe you’ve seen firsthand what happens when a sump pump fails during a bad storm and a basement gets flooded.
For most homes, it’s easy enough to manage a typical rainy season. But every so often a heavy three- or even six-inch rainstorm comes along. These rare but powerful storms can place a heavy burden on waterproofing systems and home foundations.
With massive amounts of rain coming down, your local water table is sure to rise and put your waterproofing system to the test. No two waterproofing systems are equal. Armed with the proper information though.

Interior Basement Waterproofing

During construction, exterior waterproofing is placed down to protect the foundation from groundwater intrusion. This usually comes in the form of round, corrugated drainage channels. A waterproofing or damp-proofing panel or membrane may be placed on the foundation wall as well.
The idea is that as water seeps down into the soil, water enters the corrugated drainage channels before being led to a dry well. But what exterior waterproofing systems don’t account for is the water table.
This is especially important during a storm because of the great amounts of rain that tend to come with it. If the water table rises to the exterior drainage channels, the dry well is likely to be saturated and there will be nowhere for water in the drainage channels to go. This will lead to hydrostatic pressure building up against the foundation and eventually groundwater intrusion.

Interior

To redirect water while also relieving your foundation of hydrostatic pressure, a different solution is required. This comes in the form of interior basement waterproofing.
Due to being installed around the basement perimeter and beneath the floor slab, an interior basement waterproofing system can address the rising water table. This is because of how the drainage channels are placed to catch the water and redirect it to a sump pump. The sump pump then pushes that water out through a discharge pipe and away from your home.
The end result is less water sitting against your foundation, which means less hydrostatic pressure and less groundwater intrusion. But there isn’t an one-for-all solution in interior basement waterproofing, especially when you want to prepare it for a storm. As mentioned earlier, you will want to make sure you have the right waterproofing products in place to ensure that your basement waterproofing system performs as intended.
Let’s explore what the winning factors are in a storm-worthy basement waterproofing system.
