If you're a homeowner in Waterloo, Iowa, chances are you’ve dealt with a damp basement or at least worried about one. Between heavy rainfall, freeze-thaw cycles, and notoriously dense clay soil, keeping basements dry in this part of the state isn’t always easy.

But it is possible with the right team, the right tools, and a strategy that’s built for Waterloo’s specific challenges.

At Tomlinson Cannon, we’ve been solving basement water problems in Eastern Iowa for generations. We know this area. We know the soil. And we know what it takes to keep water out–for good.

Why Clay Soil Causes Big Problems

Waterloo’s soil makeup poses a unique challenge. The heavy clay around your foundation expands when wet and shrinks when dry. That constant movement puts pressure on your basement walls especially after a heavy rain.

This pressure is called hydrostatic pressure, and over time it causes:

• Water to seep through wall cracks or floor joints
  
  
• Hairline cracks to widen and leak
  
  
• Interior paint to bubble or peel
  
  
• Musty odors or mold growth in finished spaces
  
  

What might start as a minor nuisance can quickly become a persistent issue. That’s where we come in.

How We Solve It–The Tomlinson Cannon Way

We don’t just treat symptoms, we address the source. Our approach to basement waterproofing in Waterloo starts with understanding how water interacts with your home’s foundation. From there, we create a tailored solution that fits your specific structure, soil, and water pressure levels.

Here are a few of the proven services we offer:

Crack Sealing & Wall Injection

Clay-heavy soil puts constant stress on foundation walls. When cracks form, they become easy entry points for moisture. We use a high-quality, expanding polyurethane to inject and seal cracks from the inside, bonding to the concrete and flexing with your home over time.

It’s a quick, lasting fix that prevents future seepage and protects your wall integrity.

Drainage Systems That Actually Work

For basements with ongoing water entry, we install custom interior drain systems that collect water before it can rise to the surface. These systems redirect water to a sump pump and out of your home.
