Beware of Groundwater Seeping Into Your Basement!

Spring is right around the corner, and while that might mean warmer weather, it could also mean water in your basement if your landscape isn’t properly graded. In fact, even if your grading is good and you’ve got proper roof drainage in place, you could still find yourself with basement flooding. If the culprit isn’t runoff, it’s groundwater.

Why Does Groundwater Seep Into Basements?

Groundwater is always present, but usually it’s absorbed by the soil. When the soil becomes saturated, you may see standing water on the surface—and even when this disappears, there is still liable to be a degree of saturation just below the surface. It’s this water that needs a place to go, and the first place it’s going to try and migrate to is your home’s basement. Inevitably, this is going to cause water damage in Montana.

How does it get in?

Even basements that have waterproofing measures in place are subject to ground water seepage. Many homeowners who have taken the time to specifically waterproof their foundations become frustrated when the air gets damp and small pools of water form. How does this happen? And why does this happen?

It has to do with excess groundwater content and water pressure. Heavy rainfalls in October tend to create high levels of groundwater saturation. Water is denser than air, and therefore, water will seek to infiltrate a space occupied by air. Because pockets of air in the soil have already been saturated by excess water, that water is further pushed around until it’s able to occupy a space. This is where your basement comes in.

Your basement is a huge space filled with air! Sure, there are barriers in the form of walls and waterproofing measures… but at some level these are going to be porous. When the water pressure in the soil reaches a certain level, it will actually force water through the porous material into the open airspace.

How To Stop Groundwater Damage

The best way to prevent water damage in Montana is to waterproof your basement. Essentially, this means shrinking and closing the pores that allow water to seep through. This is effective in keeping most water out of your basement—even when water pressure in the soil rises. If pressure becomes high enough, it may bypass the waterproofing in the form of condensation or humid air, but it should be enough to prevent full-on water pooling.

If your basement isn’t waterproofed, there are measures that can be taken to protect this space. First, keep everything off of the floor in case of pooling or standing water. Second, have a dehumidifier handy—this will suck moisture content right out of the air. Finally, identify problem areas and try to mitigate water seepage wherever possible—via simple waterproofing.

It’s important to remember that spring is the peak season for basement flooding. It’s a time when water saturation, water pressure and ground temperature all come together to form the perfect catalyst for flooding. Stay ahead of the season and start considering your basement today. You might just be able to prevent heavy water damage in Montana.
