Groundwater Intrusion

Groundwater Intrusion

Thanks to advances in construction and building codes, groundwater intrusion flooding isn’t usually a problem for most homeowners.  This is because builders know how to create a constant flow from the roof of a building, out the gutters and away from the foundation.  Homes and other buildings sit on the highest part of a graded slope, ensuring water runs away from the structure, not towards it.

However, extreme weather events can still cause flooding and groundwater intrusion is possible through seepage into basement or crawlspaces and leaking through thresholds at exterior doorways.  If you have experienced groundwater intrusion into your home or office due to recent heavy rains, there are a few things to consider.

Swales can help channel water away from the foundation during heavy rains or wet seasons.

The first and most important step is to check if surface water is draining at the foundation or next to the basement.  Your insurance company can help by sending someone to assess the situation, but the more you understand, the more you will be able to make the right decisions to restore your property after a flooding event.

Second, check to see if gutters are overflowing or not channeling water properly during rain storms.  Malfunctioning gutters can cause water to seep along the walls of the structure, draining it near the foundation or basement.  When gutters overflow, water can intrude higher up in the structure as well.

Evaluate downspout distance and slope if you can.  As you’re watching how water drains, see if the downspouts are hindered at all from sending water away from the structure.  Ideally, water should be discharged about 10 feet away from the foundation or basement wall.  If water is pooling at a downspout or just not channeling far enough away, consider using extenders, available at most hardware stores.  If you’re concerned about appearance, there are ways to create drainage along the ground such as a faux river bed using decorative rocks, or a rain barrel in lieu of the downspout.

Here’s a great video from Today’s Homeowner with some helpful tips on keeping your foundation as dry as possible.
