Water Intrusion in Michigan Basements

Water intrusion occurs when moisture or water gets into a building through its foundation walls, floors, or joints. Basement water intrusion may be overlooked since it starts slowly, but in Michigan, it can be a persistent issue and cause structural damage over time. Identifying the root causes and working with a waterproofing service can help you achieve long-term stability. Here are some common causes of water intrusion in Michigan basements:

Shifting Soil

Michigan’s soil is mostly clay and responds dramatically to changes in moisture levels. When the soil is wet, it expands and puts pressure on the basement walls. When the soil dries out, it shrinks, leaving gaps that could cause the foundation to settle or shift. The process of the soil expanding and shrinking makes it less stable and applies uneven pressure along the foundation perimeter. Over time, this can cause the foundation to crack or separate. These fractures are not always easy to spot, but they can slowly grow and create clear routes for water to enter. Basement repair specialists repair cracks and bowing, and level foundations that have shifted due to soil settling. Walls may be stabilized with carbon fiber straps or wall anchors to prevent collapse long-term.

Hydrostatic Pressure

Water that collects underground puts pressure on all the surfaces it touches. Hydrostatic pressure is the force that water exerts on the exterior of the basement. The pressure increases when the soil is saturated by rainwater, melting snow, or groundwater, which often happens during Michigan’s seasonal weather shifts. Even if there are no cracks, hydrostatic pressure can push moisture through the pores in concrete or masonry walls and floors.

To solve this problem, a waterproofing service installs systems, such as sump pumps, that direct water away from the foundation. Professionals also apply a waterproofing sealant to basement or crawl space walls to reduce moisture seepage from hydrostatic pressure. A polyethylene liner helps prevent water intrusions and controls mold growth, further protecting crawl spaces from moisture.

Surface Drainage

Effective water drainage usually begins with gutters, downspouts, and grading that directs water away from the house. If these systems are not working properly, they do not move water far enough away from the foundation. Water that collects near the house seeps into the ground, making the soil wetter and contributing to hydrostatic pressure.

Older homes may have experienced changes in the slope of their land due to erosion. As the land shifts, surface water may start to move toward the house rather than away from it. During heavy rain, this can result in a constant water supply around the foundation.

To solve drainage problems, the home’s exterior water management system should be reviewed. Sometimes, downspouts may require extensions, landscaping may need regrading, and water paths should be reviewed after storms to verify proper water diversion. Professionals can inspect a home’s current drainage system and recommend upgrades to promote efficient drainage.

Structural Openings

With time, the foundation may develop openings due to wear and exposure to the environment. Often, these weaknesses begin as small gaps or cracks at the joints and grow larger with every freeze-thaw cycle. The freezing temperatures during Michigan’s winters cause water in foundation cracks to expand, making the gaps larger. Openings might also develop near pipes, basement windows, or where utilities enter the house. These areas are more likely to let water in when the sealants or waterproofing materials become less effective. Professionals can inspect these areas and install new seals to protect your home.

Hire a Waterproofing Service Company

Basement water intrusion in Michigan is often related to environmental, structural, and construction-based factors. Signs of moisture intrusion should be addressed quickly to prevent cracks from widening or structures from deteriorating. A professional inspection can identify problems that are not immediately apparent, and the right service will tailor its solutions to suit your home.
