Concrete Floor Repair

Your home should be a safe and secure space, but when your concrete floors start cracking and sinking, it’s more than just a cosmetic concern; it’s a safety hazard. At Bay Area Underpinning, we understand the importance of maintaining safe and sturdy concrete floors.

With our advanced SettleStop™ PolyRenewal™ polyurethane foam injections, we can lift and stabilize your concrete floors, providing lasting solutions for your home’s safety. As the trusted leader in concrete lifting solutions in the Bay Area, we are committed to delivering personalized customer care and an effective concrete floor repair process.

This page will guide you through recognizing signs your concrete floors need repair, the benefits of our repair solutions, and why Bay Area Underpinning is the right choice for your home.

What is Concrete Floor Repair?

Concrete floor repair is the process of restoring and reinforcing interior slab floors that have experienced cracking, sinking, or other damage.

We do not recommend temporary fixes like mudjacking or DIY self-leveling concrete solutions, as they fail to address the underlying issues. Instead, our concrete lifting method tackles problems such as unstable soil or oversaturation by injecting lightweight polyurethane foam beneath the concrete to fill voids and raise the slab.

At Bay Area Underpinning, concrete floor repair is part of our comprehensive approach to solving foundation problems and creating a healthier home. If your concrete floor damage is linked to foundation issues, we may recommend foundation repair solutions like slab piers, specifically designed for homes with slab foundations.

Signs Your Concrete Floor Needs Repair

Recognizing these signs on your concrete floors indicates the need for repair:

Identifying these signs promptly can make a significant difference in the longevity and safety of your home. Consult a professional like Bay Area Underpinning at the first sign of these issues or other concerns.

Is Concrete Floor Repair Necessary?

Absolutely, repairing cracked and uneven concrete floors is essential. Neglecting damaged concrete floors can worsen problems as soil shifts and moisture penetrates beneath the concrete, potentially causing tripping hazards, further cracking, and structural damage.

Addressing concrete floor issues sooner rather than later and avoiding temporary fixes like mudjacking and DIY solutions can prevent further deterioration and save you money in the long run. Bay Area Underpinning’s concrete lifting technique stabilizes the soil beneath your floor and provides a long-lasting solution. Our other repair methods, such as slab piers, address foundation problems from the ground up.

What Are the Benefits of Concrete Floor Repair?

Repairing cracked and uneven concrete floors offers several advantages:

Creates a Safer Living Environment

Lifting and stabilizing sunken concrete eliminates tripping hazards and creates a safer environment for your family and guests. Repairing your floors brings peace of mind.

Restore Your Floor’s Appearance

Our concrete lifting process smooths cracked and uneven floors, enhancing aesthetics and restoring the sleek appearance of your home or garage’s concrete.

Enhance Property Value

Repairing damaged concrete floors protects your investment and enhances property value by ensuring an attractive, pristine floor that is more appealing to potential buyers. Homes with damaged concrete floors often sell for less.
