Benefits of Fixing Foundation Cracks with Epoxy

Fixing foundation cracks with epoxy, also referred to as “epoxy crack repair”, or “epoxy injection foundation repair” offers numerous benefits, ensuring both the structural integrity of your property and long-term durability.

Here are the benefits of fixing foundation cracks with epoxy:

Long-Lasting Results

High-quality epoxy creates a durable bond, offering a permanent solution to foundation issues.

Step-by-Step Repair Process: Restoring Foundation Cracks With Zavza Seal

At Zavza Seal, we take pride in providing a comprehensive, expert-driven repair process for fixing foundation cracks with epoxy. By combining cutting-edge foundation repair techniques with non-corrosive carbon stitching, our team ensures unmatched durability and precision for every repair.

The epoxy process includes:

Inspection:

A thorough structural inspection to assess the severity of the crack and identify key areas for reinforcement.

Preparation

Deep slots are cut perpendicular to the crack every 12 inches, followed by meticulous cleaning with a wire brush and vacuum to remove debris.

Epoxy Application

Epoxy resin is injected into the crack and slots, creating a strong seal to stabilize the foundation.

Carbon Stitching

High-strength, non-corrosive carbon stitches are embedded into the epoxy-filled slots to prevent future expansion and restore tensile strength.

Waterproofing and Reinforcement

A coat of Sika 107 waterproofing cement is applied, followed by reinforced fiber mesh to further enhance durability.

Final Seal

A second coat of waterproofing cement completes the repair, creating a fully sealed and reinforced structure.

Tips for Success

For the best results when fixing foundation cracks with epoxy, follow these essential tips:

• Ensure Proper Slot Spacing: Make sure the slots are evenly spaced at 12-inch intervals to provide consistent reinforcement across the crack. This step is critical for optimal tensile strength.
• Work in Dry Conditions: A dry environment is key to preventing moisture interference, which could compromise the epoxy bond and overall repair effectiveness.
• Adhere to Instructions: Carefully follow the guidelines for mixing and applying epoxy, inserting stitches, and waterproofing. Each material plays a crucial role, and proper usage ensures a lasting repair.

Common Mistakes to Avoid

Even a small oversight can impact the effectiveness of your repair. Avoid these common mistakes:

• Skipping Slot Cutting: This step is critical for stabilizing the crack. Missing it undermines the repair’s ability to restore tensile strength.
• Using Insufficient Materials: Ensure the crack and slots are fully filled with epoxy, and use enough carbon stitches to handle the load. Larger cracks demand extra attention to reinforcement.
• Neglecting Curing Time: Applying waterproofing materials before the epoxy cures can weaken the repair and affect waterproofing integrity. Allow adequate curing as per manufacturer guidelines.

Case Study: Fixing Foundation Cracks with Epoxy

In a recent project we performed in Oyster Bay, NY, the homeowner identified a significant structural crack running along their foundation wall and was concerned about potential structural instability. Using the techniques outlined in this guide, we applied epoxy for foundation repair reinforced with non-corrosive carbon stitches to restore the foundation’s strength and durability.

The images above showcase how each step was implemented on the foundation wall crack—from cutting deep slots and injecting epoxy to adding carbon stitches for tensile reinforcement and applying Sika 107 waterproofing cement with reinforced fiber mesh. This comprehensive process ensured a long-lasting repair, preventing further expansion and safeguarding the property.
