What is Polyjacking?

Polyjacking, or polyurethane foam injection, is a method for lifting and stabilizing sinking foundations. It involves injecting a specialized foam into targeted areas through small holes. This foam expands rapidly, filling voids and raising the concrete slab back to its original position.

The polyjacking process typically requires specific equipment and materials to achieve effective results. Here’s a common method for lifting settled concrete using this technique.

1. Inspection: A technician examines your foundation to identify problem areas, assessing cracks, uneven surfaces, and moisture issues. Tools like laser levels may be used to gauge the extent of settling.
2. Drilling: Small holes, usually about 5/8 inch wide, are drilled into the concrete slab for foam injection. The number of holes will vary based on the size of the area needing repair.
3. Injection: The foam is injected through these holes, expanding to fill voids beneath the surface and lifting the concrete. It can expand up to 20 times its original size, creating a strong support system.
4. Curing: The foam cures quickly, often within hours, allowing you to use the space soon after. This rapid curing is a significant advantage over traditional methods.

Polyjacking offers several benefits compared to traditional methods like mudjacking. The lightweight foam helps prevent further settling, and the fast curing time allows homeowners to resume normal activities often within the same day, minimizing disruption.

Be cautious of common mistakes during the polyjacking process. One major error is failing to conduct a proper inspection beforehand. Not identifying the root cause of settling can lead to more issues later. Always consult a professional to ensure the job is done correctly. Additionally, polyjacking is less invasive and requires fewer repairs to surrounding landscaping or flooring, which is a significant advantage for homeowners looking to maintain their property’s appearance.

These gaps can worsen over time, leading to larger issues. If you notice a crack wider than a quarter-inch or have trouble with doors, consulting a foundation repair expert is advisable. Additionally, signs such as staining on concrete may indicate underlying problems. Ignoring these signs can result in further damage and increased costs later.

Regularly monitoring these indicators can help ensure your home remains safe. If you notice any signs, act swiftly, and documenting changes over time can aid discussions with professionals. This proactive approach may ultimately save you time and money.

With an understanding of these key indicators, you can better address foundation issues as they arise.

How Polyjacking Works

The polyjacking process is simple and efficient, making it a popular choice among homeowners. Here’s an overview of how it works:

1. Assessment: Technicians assess your foundation to identify areas needing lifting. This step is crucial for planning repairs and determining the best approach. They may use tools like moisture meters to check for water under the slab.
2. Drilling Access Holes: Small holes, roughly the size of a quarter, are drilled into the concrete slab. This allows the foam to reach any gaps below. Typically, holes are spaced 4 to 6 feet apart, depending on the area being treated.
3. Foam Injection: A specialized two-part polyurethane foam is injected through these holes. The foam expands, filling voids and lifting the concrete back into place. The process is monitored to ensure the slab is raised evenly.

The foam cures quickly, usually within hours, allowing you to resume normal activities soon after. This efficiency reduces disruption while providing lasting support. It’s essential to choose a qualified contractor who uses quality materials, has experience with polyjacking, and can provide references from satisfied clients.

Common mistakes include skipping the assessment and not checking the contractor’s experience, which can lead to inadequate solutions and future settling. Always prioritize thorough inspections and hire qualified professionals to ensure the job is done correctly.

Benefits of Choosing Polyjacking

Polyjacking offers several benefits for foundation repair, with a key advantage being its cost-effectiveness. It generally requires less labor and fewer materials compared to traditional methods, leading to significant savings for homeowners.

This efficiency stems from avoiding extensive digging or demolition, which can be both time-consuming and disruptive. The quick process allows you to return to daily activities in hours rather than days, as the foam cures rapidly, minimizing downtime and inconvenience.

The lightweight foam used in polyjacking is strong and durable, filling voids under your foundation to provide lasting support. Homeowners can expect long-lasting results since this foam resists moisture and won’t wash away over time, leading to fewer repairs in the future.

Here’s a summary of the advantages of polyjacking:

Overview of the Polyjacking Process

Understanding the polyjacking process involves several key stages, starting with a thorough inspection by a technician. This assessment identifies areas that require attention, typically examining for:

• Visible cracks in walls or floors
• Uneven surfaces
• Signs of moisture
• Shifting or settling of the foundation

Once the assessment is complete, small holes, usually about 5/8 inch wide, are drilled into the concrete slab. This allows for adequate coverage of affected areas and enables the foam to access necessary voids. The number of holes drilled will depend on the extent of the settling.

Next, specialized polyurethane foam is injected through these holes. The foam expands upon contact with air, filling voids beneath the slab and lifting the concrete back to its original position. This method is efficient and minimizes the risk of further damage.

After the foam cures, sealing the holes is crucial to prevent water intrusion. Proper sealing creates a stable foundation ready for immediate use and helps maintain the integrity of the repair against moisture.

Avoiding common mistakes during the polyjacking process can lead to better results. Learning from others’ experiences can enhance your approach. Key pitfalls to watch out for include:
