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.

It might be a hairline crack in the garage. A door that suddenly sticks and won’t close. 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. Here in Irvine, our soil and water can be tough on a home’s structure. Ignoring these signs can lead to spiraling repair costs, decreased property value, and serious safety concerns.

You need a partner you can trust. 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 with comprehensive concrete foundation repair and foundation waterproofing in Irvine.

Why Irvine Homes Are at Risk

In Southern California, our foundations are under constant, quiet stress. The “expansive clay” soil common in our region acts like a sponge. It swells when it gets wet (from rain or irrigation) and shrinks dramatically when it dries. This constant movement puts immense pressure on your concrete foundation, causing it to shift, crack, and settle.

This is where the problems begin.

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 one of these common symptoms.

Outside Your Home:

• Cracks in the foundation slab or walls (vertical, horizontal, or “stair-step” cracks).
• Gaps appearing between your chimney and the side of the home.
• The foundation itself appears to be sinking or has “heaved” upward.
• Patios or walkways pulling away from the house.

Inside Your Home:

• Cracks in drywall, especially over doors and windows.
• Doors that stick, or windows that are suddenly hard to open and close.
• Floors that feel “spongy,” sloped, or uneven.
• Popped nails in your drywall.

In Your Basement or Crawlspace:

• A persistent musty, “damp” smell (a sign of mold and mildew).
• Visible water, damp spots, or puddles on the floor.
• White, powdery (efflorescence) on the concrete walls.
• Cracks in the walls, especially with water seeping through.

If you see any of these, it’s time to call a professional. Looking online for “foundation repair companies” can be overwhelming. You need a specialist.

Our Expert Foundation Repair Solutions

As the premier foundation contractors in Irvine, we offer a complete suite of services. Our process always starts with a thorough, no-obligation inspection to find the source of the problem, not just the symptom.

1. Concrete Foundation Repair

When the structural integrity of your foundation is compromised, we deploy precise, engineered solutions.

• Epoxy & Polyurethane Injection: This is the most effective method for basement crack repair. For structural cracks, we inject high-strength epoxy that “welds” the concrete back together, making it stronger than it was before. For non-structural cracks that are leaking water, we use an expanding polyurethane foam that fills the void and creates a permanent, flexible, and waterproof seal.
• Carbon Fiber Reinforcement: For bowing or leaning foundation walls, we use carbon fiber straps bonded to the wall, locking it in place and preventing further inward movement.
• Foundation Stabilization: For sinking and settling, we use underpinning and other engineered methods that lift and stabilize the foundation, transferring the load to solid ground for a permanent fix.

2. Expert Foundation Waterproofing in Irvine

A dry foundation is a healthy foundation. Our foundation waterproofing Irvine services are designed to stop water before it can ever touch your concrete.

• Exterior Waterproofing: We excavate the soil around the foundation, clean and inspect the walls, repair cracks, and apply a high-tech waterproof membrane that seals out moisture completely.
• Interior Water Management: When exterior work isn’t possible, we install an interior drainage system (French drain) and sump pump that capture water and redirect it safely away from your home.

We See the Whole Picture: Your Home as a System

The GAGA US Construction difference is our experience. Unlike many foundation repair companies that only offer one service, we are a full-service construction team. We understand that your foundation problem is often connected to other issues around your property.

• Demolition, Excavation & Grading: Poor grading is the #1 cause of foundation problems. Our excavation team can regrade your property to ensure water flows away from your home.
• Concrete & Asphalt Repair: Foundation issues often go hand-in-hand with sinking patios and cracked driveways. While repairing your foundation, our concrete repair team can fix your other concrete structures as well.
• Pavers & Hardscaping: Solve drainage problems beautifully with a paver system designed to direct water away from your foundation.

Your Foundation Questions, Answered

Q: Will your inspection cost me anything?

A: No. Our inspection and consultation are completely free, with no obligation.

Q: Why choose GAGA?

A: We are true foundation contractors Irvine residents trust. We bring decades of local expertise and provide permanent, engineered solutions—not patches.
