Waterproofing Below Grade Prior to the Spring Thaw

As any homeowner knows, spring is the time of year when the weather starts to warm up and the snow starts to melt. However, it can also be the time of year when homes start to experience water damage. Waterproofing below grade prior to the spring thaw can help prevent water damage and keep your home in good condition. 

There are a few ways to waterproof your home, and the best method depends on the specific needs of your home. 

The Dangers of the Spring Thaw to Basements

As the weather warms, many people begin thinking about home improvement projects. One area often neglected is the basement. However, the spring thaw can actually pose a serious danger to basements that are not properly prepared. 

When the snow and ice melt, the resulting water can seep into cracks in the foundation, causing flooding and water damage. Additionally, the increased moisture can create an ideal environment for mold and mildew to grow. Therefore, it is important to take steps to protect your basement from the spring thaw. 

One way to do this is to ensure that all cracks in the foundation are properly sealed. Another is to install a sump pump to remove any water that enters the basement. By taking these precautions, you can help keep your basement safe during the spring thaw.

Verify Yard is Properly Graded

Improper yard grading is one of the leading causes of water damage to homes. During the winter months, when rain and snow are more prevalent, water can pool in low areas of your yard and seep under the foundation of your home. This can lead to many problems, including cracks in the foundation, mold growth and even flooding. By ensuring your yard is properly graded, you can help reduce the risk of water damage to your home. 

Grading involves creating a gentle slope away from your house, so that water will drain away from the foundation. This can be a difficult task, but it’s well worth the effort to protect your home from water damage.

Check Egress Windows for Sealing Issues or Cracks

When spring arrives and the snow and ice start to melt, your home is at risk for water damage. One of the most vulnerable areas is your windows. If they are old and have cracks or are improperly sealed, they can let in water. This can lead to stained and damaged walls, carpeting and furniture. In severe cases, it can even cause mold and mildew to grow. To avoid this, check your windows before the thaw begins. If you see any cracks or gaps, seal them with caulk or weatherstripping. 

You should also check the seals around your windows to make sure they are intact and in good condition. By taking these simple steps, you can help protect your home from water damage this spring.

Waterproofing Below Grade

Waterproofing below grade prior to the spring thaw can be beneficial because it helps prevent water damage caused by melting snow and early spring rains. It also helps keep mold and mildew from growing and can help prevent your basement from flooding.
