In Iowa, small cracks in your foundation can become big problems, especially when water starts finding its way inside. What begins as a hairline flaw can turn into a steady leak, leading to mold, musty smells, and damage to walls, floors, or stored belongings.
At Anchored Walls, we’ve been helping homeowners in Winterset and the surrounding areas protect their homes from basement water for over 40 years. If you’ve noticed a leaking crack in your foundation, we’ll find the right solution and fix it with care and precision.
Foundation cracks are common in homes throughout Iowa. Some form during the curing process as concrete settles, while others are caused by shifting soils, temperature swings, or poor exterior drainage. Over time, these cracks can widen or deepen, especially when exposed to hydrostatic water pressure from the surrounding soil. Once water gets in, it doesn’t stop on its own.
Fixing a leaking crack early can prevent much bigger repairs down the road.
Left untreated, even small leaks can lead to structural deterioration, mold growth, ruined finishes, and increased energy bills due to humidity. Over time, water infiltration can widen cracks and weaken foundation walls—especially during Iowa’s freeze-thaw cycles. Timely repairs protect both your home’s structure and indoor air quality.
Not all cracks look threatening at first glance. Some may not even be visible behind finished walls or stored items. Keep an eye out for these common signs that water is entering through a foundation crack:
If you’ve noticed any of these warning signs, it’s time to take action.
Anchored Walls offers interior repair options based on the foundation type and the severity of the leak.
For poured concrete foundations, we typically use a two-step injection process to seal the crack from the inside. After cleaning the area and placing injection ports along the crack, we apply a surface sealant to hold the material in place. Once cured, the crack is filled with either polyurethane or epoxy resin—polyurethane is ideal for stopping active leaks with its flexible, expanding form, while epoxy provides a strong, rigid bond for structural stability. Both materials penetrate the full depth of the wall for a lasting, watertight seal.
Think of injection like filling a crack in a windshield—if it’s sealed early, it won’t spread. The resin fills every crevice, even the ones too small to see, and bonds with the concrete to prevent future leaks. Our team makes sure the repair isn’t just watertight—it’s built to last.
Depending on the size and severity of the crack, we may adjust the repair approach:
