Basements are an absolutely fantastic and clever construction, but they are also prone to water damage because of how low they are built. You must notice moistness on your basement walls, especially during rainy days. Damp, humid, and wet basements can promote wood rot, mildew, mold growth, and damage to stored items, which is why protecting your basement from water damage is critical. 

Let us look at a few reasons why you need to shield your basement from water damage and how you can do so. 

Potential Reasons For A Wet Basement 

Wet basements are most commonly caused by internal complications, such as leaky pipes and condensation, and external reasons, such as poor drainage and groundwater. 

Cracked Foundation Walls 

Foundation walls with holes and cracks in their surfaces can allow water seepage from either on-grade water or groundwater, resulting in undesirable consequences for your otherwise dry basement. 

Interior Condensation

Water condensation on the floor and walls is a common consequence of humid basement air, which can eventually seep into the structure. A drastic temperature difference between hot and cold air can also cause it. 

Doors and Windows 

It is common for water to seep in through basement windows and doors, even when you make a point to seal them shut. Such water leakage can also occur through upper-floor doors and windows, trickling down to your basement walls. 

Leaky Pipes 

Basements typically house a big chunk of a house’s electronic equipment, such as pipes, water heaters, AC units, furnaces, washers, and many more. The water supply pipes fitted into the walls or ceilings of basements can leak, potentially affecting the structural integrity of your basement. 

Groundwater

Leaking pipes and windows are not the only way for water to make its way to your basement; groundwater can also play its role. Since sand, rocks, and dirt is porous, they can absorb ground water, causing it to come up from the foundation walls or your basement floor to cause water intrusion complications.

Seal Walls 

You need to use a moisture tester to identify which walls allow outside water to seep into your basement. Once you find the culprit, you can buy a masonry waterproofing product and use it to hinder the moisture. You may have to use two or three coats of the product to build a proper barricade against the invading trace amounts of water. 

Fill In Cracks 

One of the most straightforward ways of waterproofing your basement is by filling basement foundation walls with hydraulic cement. A paste is made out of this specialized cement, which is then applied into the cracks with a putty knife or even your bare hands. Make sure to apply a decent amount as the cement expands to cover the entirety of the crack’s surface area. 

Consider A French Drain 

A French drain is a specialized trench in the basement floor that allows water a diversion to flow to a sump basin. Made out of gravel and perforated pipe, this drain effectively sucks up water from all parts of your basin and allows a diversion through the sump pump to the outside.

Fix and Improve Gutters 

Keeping your basement gutters in top-notch shape is critical to ensure a proper pathway for unrequired water to be directed outside. But if your house is built on a downward slope or is surrounded by concrete hardscaping, nature is on your side, and you may not need to install such gutters. 

Grade The Yard 

You can grade your yard yourself, all with a wheelbarrow, shovel, and extra fill dirt. Thoroughly grading the yard expels external water from the basement and foundation and keeps your space clean and dry. 

Seal External Foundation Walls 

External foundation walls are the primary culprit of most water intrusion complications and must be sealed. Off through liquid synthetic membranes. You can also use a cementitious coating to securely seal the outside of your basement. Walls from extra moisture, or go for a synthetic sheet membrane or solid bentonite sheets. 

It is important to note that external water sealing is not as simple as coating them with a product. The process requires soil to be dug out from the foundation wall’s bottom. You may also have to install drain tile at the trench’s bottom to ensure proper protection from water drainage. 

Install An Exterior French Drain

French drains do not only go inside a basement; you can also install it outside. External French drains are a trench lined with gravel. Weed-block fabric, and a perforated pipe to direct water from your basement’s foundation. They are a great addition for yards where water pooling is common and threatens your basement’s foundation. 

Summing Up 

Waterproofing your basement may seem unnecessary, but it determines the strength of your house’s foundation. Small amounts of water seeping through the floors and walls may seem harmless but can cause hefty renovation expenses. In the long run, damaging your house and basement’s structural integrity on the way. 
Thus, waterproofing your basement before a serious issue unfolds is generally. A wise choice and one we expect you to make. Visit here to related post to learn more!
