Basement Sealing & Waterproofing in Des Moines: Protecting Your Older Home

Des Moines is a city rich in history and character, and its homes reflect that charm. 

Nestled along the Des Moines River, the city boasts neighborhoods filled with historic architecture and timeless beauty. With the median year homes were built being 1955 and over 37.5 percent constructed before 1940, many Des Moines homeowners live in properties with aging foundations. 

These older homes often face challenges with moisture, making basement sealing and waterproofing a top priority to maintain structural integrity and comfort.

Des Moines experiences a humid continental climate with hot summers and cold, snowy winters. 

The city receives an average of 36 inches of rainfall and about 33 inches of snow annually. This precipitation contributes to higher groundwater levels, which can lead to increased moisture around your home’s foundation. 

The soil in the region is often clay-rich, which means it can retain water and expand, putting additional pressure on basement walls. During freeze-thaw cycles in winter, this soil can contract and expand, causing cracks and gaps where water can infiltrate.

• Flooding from the Des Moines River: Proximity to the river increases the risk of basement flooding during heavy rains or rapid snowmelt.
• High Humidity Levels: Summers can be quite humid, leading to condensation and moisture buildup in basements.
• Snowmelt Issues: Rapid melting of snow can saturate the ground, causing water to seep into basements through foundation cracks.

Interior Drainage Systems

Installing an interior drainage system can help manage water that enters your basement. These systems capture water seepage and channel it to a sump pump before it can cause damage.

Sump Pumps

A reliable sump pump is crucial for removing accumulated water. Considering the high water table in some areas of Des Moines, a sump pump can prevent flooding during heavy rains or snowmelt.

Vapor Barriers on Walls

Applying a vapor barrier is a great way to include basement sealing and waterproofing to your basement walls. A vapor barrier seals out moisture and prevents mold growth. This is especially important in older homes with very porous foundation materials.

Installing a FreezeGuard

Given Des Moines’ freezing winter temperatures, installing a FreezeGuard on your sump pump’s exterior discharge line is a smart precaution. The FreezeGuard provides an emergency escape route for water, ensuring it can flow freely even if the discharge pipe freezes. Preventing backflow issues and helping keep your basement safe and dry during the harsh winter months.

Regular Maintenance

Regularly inspect your basement for signs of moisture, such as damp spots or mold. Early detection can save you from more significant repairs down the line.
