Dos of basement waterproofing

1)   Find out the source of water/leaks

Look for damp areas and streaks of water around the window corners, ground, cracks, pipes, and other areas where you suspect water can come in from the outside. Since concrete is porous, you can easily find streaks on the walls. If the whole wall is wet, then you should do a test.

Properly dry a part of the wall and attach a small aluminum foil to the wall; after a day, detach the foil and feel the inside of the foil; if it is wet, then water is coming from the outside. But if it is dry, then the source of this dampness is from the inside. So take measures accordingly so that it doesn’t keep making your basement feel damp and humid. Apply a layer of waterproof paint which is a type of sealant. It covers all the small areas and prevents them from seeping inside.

2)   Make sure the gutters are maintained and clean.

Clogged gutters are a disaster. For instance, if your rain gutter gets clogged and then dumps all the water against your home’s foundation, then it can cause a problem for your basement. This is why it is important to maintain your gutters and keep them free from leaves, dirt, and debris so that water makes its way into the drainage system and not your house.

3)   Use hydraulic cement to fill up the cracks

Cracks can also be found near the bottom of the walls in your basement. The construction procedure leaves weak spots in the foundation joints. The cracks can develop during the settling and shifting of the foundation. This can be prevented by using hydraulic cement, which is the cement that expands and sets easily and rapidly. So all the cracks and holes can be easily filled with it.

4)   Take measures to ensure water stays away from the basement

You can also keep water away from the basement by keeping the foundation flower beds and bushes away. Also, it is best if your yard can be away from the foundation. Repair downspouts and drainage system so that water is directed away from the house. Waterproofing can also be applied to the outside of the basement wall, and an exterior drain system can also be made. So it is best to hire an affordable basement waterproofing company and consult with them.

Don’ts of basement waterproofing

1)   Avoid DIY sealants

There are many options in the market when it comes to sealants and waterproofing methods. But not every option can be good for your basement because your basement problem is unique. It is important to consult with professionals to find the right solutions to the problem.

2)   Never apply your sealant over painted walls

It is advisable that you remove the previous paint layer of your wall before applying the sealant that adheres well to the bare wall only.

3)   Never ignore a crack or leak

The most ignorant thing you can do for your basement is to ignore the signs of leakage. Even if it is small, you should never ignore it, as it may turn into a bigger and serious problem. One place of common leaks is the window wells, where water is retained if a proper drainage system was not made outside. This water can then seep in. Apply a proper sealant around the wall and install a sloped window cover outside so that rainwater stays away. Basement waterproofing is a wise investment because it will save you from a lot of stress, time, and money spent in the long run.

4)   Never ignore the importance of indoor drainage

A proper drainage system in your basement can ensure a dry and clean basement. You will require the help of a professional. Once you have a proper drainage system inside, your walls will be dry, and your basement will be free from moisture and dampness. All the water that seeps into the old walls will be directed away through the drainage channels.

5)   Keep downspouts away from your house

The purpose of downspouts is to keep water away from the house, but if they shoot water against your house, then it can be problematic for your basement.

6)   Never repair walls with water in your basement

Cracks can cause leakage of water inside your basement. But before you repair the leakage, you need to remove all the water and make your basement dry again. A flooded basement will not only not let you repair the crack easily; it might even increase your chances of getting an electric shock. So turn off the power and use pumps to remove the water. After the water is removed, you can easily inspect the cracks and fix the issues effectively and efficiently.
