Cracks, Water, or Sinking? Your Expert Guide to Foundation Repair and Waterproofing in Irvine
Of all the parts of your home, the foundation is the easiest to ignore. It’s out of sight, and we all just trust that it’s doing its job. That is, until the day you notice a problem: a hairline crack in the garage, a door that suddenly sticks, or a musty smell in your crawlspace.
These are not small “house settling” issues to put on next year’s to-do list. They are early warning signs from your home’s most critical component. Ignoring these signs can lead to spiraling repair costs and serious safety concerns.
At GAGA US Construction, we are the expert foundation contractors Irvine homeowners have relied on for years. We don’t just patch problems—we solve them for good.
Why Irvine Homes Are at Risk
In Southern California, our foundations are under constant, quiet stress. The culprit is often the ground itself.
The "Expansive Clay" Danger
The soil common in Irvine acts like a sponge. It swells significantly when wet (from rain or irrigation) and shrinks dramatically when it dries. This constant movement puts immense hydraulic pressure on your concrete foundation, causing it to shift, crack, and settle over time.
Don’t Ignore These Warning Signs
Your home will tell you when something is wrong. The key is to listen. When we get calls from homeowners, they often report these common symptoms:
Outside Your Home
- Stair-Step Cracks: Distinctive jagged cracks in brick or stucco walls.
- Chimney Gaps: Gaps appearing between your chimney and the siding.
- Separation: Patios or walkways pulling away from the main house structure.
Inside Your Home
- Sticking Doors: Doors or windows that suddenly won't close properly (a sign the frame has shifted).
- Drywall Cracks: Cracks appearing specifically above door frames or window corners.
- Uneven Floors: Floors that feel "spongy," sloped, or uneven.
Our Expert Foundation Repair Solutions
As the premier foundation contractors in Irvine, we deploy engineered solutions based on the specific type of failure.
1. Injection Repair: Epoxy vs. Polyurethane
We use two distinct methods depending on whether the crack is structural or leaking.
| Method | Best For | How It Works |
|---|---|---|
| Epoxy Injection | Structural Cracks | "Welds" the concrete back together, making the bond stronger than the original wall. |
| Polyurethane Foam | Leaking / Wet Cracks | Expands to fill the void, creating a flexible, permanent waterproof seal to stop leaks. |
2. Structural Reinforcement
For bowing walls, we utilize Carbon Fiber Reinforcement. These high-strength straps are bonded to the wall to lock it in place, preventing any further inward movement without the need for invasive steel beams.
3. Foundation Waterproofing in Irvine
A dry foundation is a healthy foundation. Our waterproofing services are designed to stop water before it touches your concrete.
- Exterior Waterproofing: We excavate the perimeter, repair cracks, and apply a heavy-duty waterproof membrane.
- Interior Management: We install interior French drains and sump pumps to capture rising water and redirect it away from your basement or crawlspace.
