French Drains and Their Use

To prevent yard flooding, you’re going to want to take advantage of something called a French drain. These drains are elongated traps for water – like a gutter that’s installed in the ground. These drains are frequently used to prevent yard flooding as well as garage flooding. They can be installed at the bottom of a sloped driveway or yard.

French drains are typically covered in a grate, gravel, or garden rocks. Water will flow past these coverings and collect in the drain. The water is then redirected away from the house, keeping the soil around your home from becoming saturated with water. When surrounding soil is considerably wet, the water will travel to where basement walls or your foundation are and find its way in through small cracks, invisible to the naked eye. This can lead to basement flooding as well as expensive structural damage.

Installing a French Drain

Installing a French drain will involve some invasive digging. A trench will be dug through your yard, where water collection is desired. Once the drain is installed, however, it can be covered up again in a way that hides it from view. Whether you want to use garden gravel or stones to cover the drain is up to you and what you want your yard to look like when it’s finished.

Prevent Yard and Basement Flooding

When your French drain is installed, your yard will no longer flood when it rains. Instead of pooling at the low part of your yard, the water will collect in the drain and flow away from the house. A French drain may have an outlet in a nearby storm drain or ditch. If you live in a rural area, the redirection may just end a short distance away, at a lower level than the house. That way, the water will collect in the ground without causing any structural issues to your home.

With water being moved away from the home, the soil around your basement will remain much dryer. This significantly lowers the chance of your basement taking on moisture or completely flooding. If you’re experiencing basement moisture or flooding issues even after installing a French drain, you may need to consider exterior basement waterproofing or damp proofing.

When looking for solutions to home moisture or flooding problems, you’ll come across two terms often: damp proofing and waterproofing. Contrary to popular assumption, these are two different things! In order to ensure your home’s water problems are solved properly, knowing the difference is vital. So, damp proofing vs. waterproofing – what are their differences?

Damp Proofing

As you might expect, damp proofing is protecting something against dampness. While that may not seem different from waterproofing, the difference lies in the degree of protection.

If you have a basement, regardless of whether the interior is finished, the basement will be surrounded by stone walls. Whether these are cement or stone brick makes little difference. The reason this matters is that stone is not as waterproof – or damp proof – as people think it is. While stone does a good job of keeping water at bay in small quantities, consistent dampness attempting to infiltrate stone walls will, eventually, succeed.

Stone, basement walls are holding the weight of all of the house structure sitting on top of them. After even just a few years, microscopic cracks will form in the walls. These cracks may be too small to see with the naked eye, but moisture doesn’t need to see cracks to find its way inside of them.

This moisture can make its way to the interior of the basement. This will cause mold in finished basement walls or becoming visible moisture on the surface of an unfinished basement wall. Damp proofing seeks to prevent this moisture from getting inside.

Waterproofing

Waterproofing, like damp proofing, is done to keep water from getting into your basement. The difference is in extensivity. Damp proofing keeps moisture from the soil from seeping in. Waterproofing protects your basement walls from excessive groundwater. For example, if your yard slopes toward your home, rain will run down the hill and collect against the walls of your basement. This is what waterproofing seeks to prevent.

If left unchecked, this kind of water buildup against a basement wall can lead to basement flooding. The longer water is allowed to enter cracks in the wall, the more the cracks will widen from erosion. This, in turn, allows more water to enter your basement. It also hurts the integrity of your basement walls. Eventually, you may end up with significant amounts of water coming into your basement when it rains. It may pool along the wall or even advance in intensity until it covers the entire floor, pooling up and flooding the basement.

Which One Is Right for You?

When it comes to damp proofing vs. waterproofing, choosing can be tricky. The question of which method is right for you depends entirely on what kind of problems you’re experiencing.

If the water getting into your home has been getting progressively worse since you moved in, it may be a sign that cracks are widening. If your yard slopes or you live at the bottom of a hill, you should probably invest in exterior basement waterproofing.

However, if you’re simply experiencing moisture on your basement walls, damp proofing may be all that’s necessary. Before investing, you should also confirm the source of your moisture issues.
