Waterproof Foundation Quad Cities

Stability Starts Below the Surface

Whether you’re in Davenport, Bettendorf, Rock Island, or Moline, one thing is true across the Quad Cities: foundation problems tend to start with water. Saturated ground, rising water tables, and unpredictable freeze-thaw cycles all place stress on your home’s foundation. And if your property sits in a low-lying area or near the river, the risks go up even more.

That’s why smart homeowners are investing in foundation waterproofing before damage becomes permanent.. or expensive.

At Tomlinson Cannon, we’ve been helping Quad Cities residents protect their homes for over 75 years. From wall anchoring to deep piering systems, we offer proven solutions that keep your foundation stable, dry, and secure.

Waterproof Foundation Quad Cities

Why Water Is a Bigger Deal Than You Think

Water doesn’t need an open door to get into your home. It pushes its way in slowly–through tiny cracks, soil expansion, and pressure shifts. Here in the Quad Cities, a combination of high water tables and shifting soils creates the perfect storm for foundation movement.

This often shows up as:

• Cracks in walls (especially near corners or windows)
  
  
• Bowing or leaning basement walls
  
  
• Sticking doors and sloping floors
  
  
• Moisture in crawl spaces or around footings
  
  

If you’ve noticed one of these signs, it’s time to act before minor issues turn into major structural repairs.

How We Fix It and Why It Works

Every home is different, but many of the problems we see in the Quad Cities come down to pressure from unstable soil or underground moisture. We take a two-pronged approach: relieve that pressure, then reinforce the structure.

Wall Anchoring with Grip-Tite®

When walls are bowing or starting to lean inward, our Grip-Tite wall anchoring system restores them to position and locks them in place. Anchors are installed quickly, usually from outside the home, and work by counteracting the external soil pressure.

They’re fast, strong, and backed by a warranty you can count on.

Foundation Piers for Sinking or Settling

If your home is experiencing vertical movement often caused by soft or saturated soil beneath the footings, then we’ll install foundation piers. These steel piers reach deep into stable ground, lifting and stabilizing the structure permanently.
