Why Is Interior & Exterior Basement Waterproofing Necessary?

If water gets in your basement, it can severely affect foundation, damage your keepsakes, and lead to mold growth. That's why you should learn how to waterproof basement walls, and how we can help.

Water in the surrounding soil finds its way through cracks and pores in the walls to reach your basement. Especially, concrete walls are porous which allows the water to seep through, leading to a wet basement, necessitating basement waterproofing.

Moreover, the probability of water seepage in your basement increases if you live in an area prone to heavy rainfall, snowstorms, or heavy snow melts. Whenever water seeps into the interior spaces through your home’s foundation, it can cause a significant amount of damage. The damage can adversely affect the structural integrity and value of your home unless you act in time and initiate waterproofing basement walls from outside or inside.

Homeowners should take immediate preventative actions to stop basement water flooding. You should put in enough time and effort to make sure the home is in nearly perfect condition.

But it can be confusing to choose the best option for you, i.e., should you try waterproofing the basement wall from inside or outdoor? You also have to think about hiring an expert company to do the work. You must see the facts regarding basement waterproofing interior VS. exterior methods and then judge which one is suitable for your home.

What Is Interior Basement Waterproofing?

Interior basement waterproofing involves waterproofing basement walls from the inside. This way, the water that leaks into the basement is re-routed, before it can come in, out and away from your home. It is an effective waterproofing method and a much less offensive alternative to exterior waterproofing.

Application of waterproof coating on a foundation for interior basement waterproofing

The interior basement waterproofing system manages the water by removing the groundwater swiftly before it touches your floor. It includes the use of interior sealers and drainage systems. Interior drainage systems are made up of pipes and drain that catch leaks or are installed under the foundation to collect excess groundwater. 

Excess water is moved towards a large basin called a sump pit that collects water and discharges it away from your home using a sump pump.

Investing your money in waterproofing interior basement walls can reduce the risks of water flooding in your basement. These drainage systems are easy to install and generally cost less than exterior waterproofing costs.

What Is Exterior Basement Waterproofing?

The exterior basement waterproofing is also an incredibly effective method to keep the water out of your home. When dealing with wet basements, most problems arise because of the outside environment. Therefore, it is necessary to look at the exterior portion of the basement and consider waterproofing basement walls from the outside.

Digging up damp soil surrounding a foundation for exterior basement waterproofing

An exterior basement waterproofing system involves excavating the soil surrounding the foundation of your house. The consistently soaking soil around the house expands and puts pressure on the foundation, causing it to shift and crack. The groundwater then creeps its way through the cracks into your home.

But the exterior basement waterproofing can be a labor-intensive procedure and requires several tools and machinery. After excavating the soil around the home’s foundation, a polymer-based waterproof sealant is applied to the exterior walls of your basement to prevent water seepage.

What Is The Difference Between Interior And Exterior Waterproofing Methods?

Exterior basement waterproofing is an expensive and complicated procedure in contrast to interior basement waterproofing. The approach needs the exclusive expertise of laborers to help get efficient results. If you hire a contractor with less experience to save your money, it might cost bags of money in the long run.

Exterior waterproofing is also a bit more involved than interior basement waterproofing systems. Interior basement waterproofing is considered a counteractive solution for when the water has already entered the home, while exterior waterproofing is more of a preventive method for keeping your basements dry in the future.

Interior systems redirect water out of your home. It works by digging a water collection trough and installing a sump pump for water removal from the basement. But, the exterior system is installed outside of your foundation to prevent water from entering your basement.

The exterior waterproofing process includes excavation of soil surrounding your home and repairing the leaks using a powerful sealant. Interior basement waterproofing systems are considered better and more effective in preventing wet basements. The interior weeping tile system can waterproof your basement.
