If basement waterproofing in your home is done incorrectly, you may face a lot of issues in a while. You may believe that everything works properly but, oops!, you encounter a sudden water seepage somewhere and a lot of mildew, mold, stuffy air, and wall cracks cause much damage that needs immediate care.
You can try to do something about it but, if repairs are done unprofessionally, the problem will not disappear. For example, you have applied coating but the issues emerged from the outside.
So, let us discuss how to waterproof a basement correctly to avoid many problems.
The best waterproofing methods for basements
1. Waterproofing of the Basement from the Outside
To prevent water issues, consider waterproofing basements from the outside. This can be accomplished with the help of different basement waterproofing methods. They are applicable when you want to ensure the reliable basement waterproofing from the outside.

Excavation is often used when you need to waterproof your basement. After it is done, clear out the walls from debris and look attentively at them. They may have small cracks or damaged surfaces that allow the water to penetrate the house. Check for normal, horizontal, vertical foundation cracks, hairline crack in foundation, and other damaged areas. To prevent further leakage, think about the hydraulic cement coating. After it has cured, such cement expands due to its chemical components. The substance seals the cracks or voids and the leakage is impossible.
Make a Drainage Ditch Effective
If your backyard and basement are constantly wet, you may opt for a drainage trench. You can choose different methods to dig such a ditch. Address this work to professionals to get such a trench anywhere in your property.
Never Arrange the Rain Gutters Too Close to the Foundation
The rain gutters are usually arranged from the roof. However, never install them too close to your foundation. Check whether you can revamp the gutter spout by a special extension that can be bought in the nearest hardware store. The idea is to drive the excess water out and away from your foundation as far as possible. Another method is about setting up the gutters underground. They can run to the sump pit that way.

Maintain the Surrounding Landscape for Better Basement Protection
Look around. Try to notice how sloped the landscape is around the foundation. Or maybe, it is completely flat, or, what is worse, the slope may run towards the basement. The latter can occur in older households because the foundation can settle much over time and the ground around it gets compressed. Try to direct the slope away from the foundation but not leave it running towards it.
Use the Sealant
The cement-based sealant is a good way of waterproofing. It should be used on the exterior walls. The use of such sealants is quite easy and they can be applied to masonry or concrete walls. When the sealant hardens, it blocks the pores in the material to prevent water seeping. Even if there is a hairline crack somewhere on the wall and it hasn’t been fixed with hydraulic cement, this procedure can help to get rid of it.
Utilize a Membrane
Your basement walls may need some heavy coating. Install a waterproofing membrane. It is made of the special polyurethane components and asphalt-modified materials. You can use spraying or trowelling to apply it to the walls. The reliable protection against the exterior water seepage is created in this way. Because this elastomeric membrane is made of the modified asphalt, it displays perfect waterproofing features.
2. Interior Basement Waterproofing
Repairing a Sump Pump in a Leaky Basement
Installing and maintaining a sump pump is one of the most wide-spread interior basement waterproofing methods that can control the water seeping inside the basement. If the sump pump is installed in your home but the waterproofing issues are still present inside, something is wrong with the sump pump or its installation. You can detect the source of the issue yourself. You need to check whether your sump pump is as effective as it is meant to be. Maybe it does not let enough water in the drain. Or maybe it is clogged, not powerful enough, or just broken. You always need to have some spare pump installed in case there is a lot of water coming from the outside. Or you may need to obtain a pump of a better quality and power to cope with the flow of water coming into your basement. The big plus of a more powerful pump is that it works a bit quieter. Your sump pump may also be located incorrectly. It should be installed as close to the foundation as it is possible.
Using the French Drain
The materials used for foundations in older houses can be very porous. That is why they cannot prevent water from penetrating. Using French drains is a wise solution here. They help collect the excess water and drive it away from the house. You can learn more about how to install the French drain in your home from our further materials.

EPDM Waterproofing Membrane – It is a single-layer waterproofing membrane made of rubber. The method is widely used for waterproofing. The rubber is of a special type, synthetic EPDM which is very reliable and cost-effective working more efficiently than any substitutes.
Cementitious Coating – This is also a membrane made of the special acrylic-modified and flexible cement-based Portland compound that is very effective when applied to the basement walls. It can resist any pressure, be it positive or negative, when placed under the water or below the ground.
New Build Reinforced Concrete – This waterproofing system is also based on cement. It displays its best efficiency when applied to concrete surfaces. The action is provided by its active chemical elements that bond with the lime and moisture in the pored surfaces and make up the whole crystalline complexes which are resistant to water. These crystals coat the capillaries and minor cracks that are always present in the concrete and no excess water can penetrate from the outside anymore.
