Void Filling Services in Washington & Northern Idaho

Voids in concrete structures, including those found in slab on fill foundations, pose significant challenges to property owners and construction professionals. These hidden cavities can lead to structural instability, safety hazards, and costly repairs if left unaddressed. Here at Slabjack Geotechnical, we offer reliable void filling services to tackle these issues head-on, ensuring long-lasting results for our clients. Our team uses advanced techniques and high-quality concrete void filling foam to restore strength and stability to compromised structures.

Our Comprehensive Void Filling Process

Our comprehensive void filling process can stabilize and restore concrete structures compromised by voids. Utilizing advanced detection methods and high-quality concrete void filler, we effectively address the root causes of instability. Our expert team is committed to delivering long-lasting results with minimal disruption to your property.

1. Initial Site Inspection and Void Detection: Our void filling services begin with a thorough site inspection and void detection using underground cameras to assess the extent of the problem.
2. Strategic Drilling of Injector Ports: We strategically drill small injector ports into the affected concrete area, allowing us to inject our specialized polyurethane foam.
3. Injection of High-Density Polyurethane Foam: This high-density foam expands rapidly, filling voids and stabilizing the surrounding soil.
4. Lifting and Leveling Through Polyjacking: As it cures, it lifts the concrete back to its original position through a process known as polyjacking or slab lifting, ensuring a level surface.
5. Monitoring and Adjustment: Our team carefully monitors the poly foam injection process, adjusting it to achieve optimal results.
6. Seamless Finishing: Once complete, we patch the drill holes, leaving a seamless finish.

Understanding Void Formation: Causes and Consequences

Void spaces under concrete slabs occur when supporting soil beneath the concrete is lost. This can happen due to various factors, includingsoil erosion, poor soil compaction during construction, andwater drainage issues. One of the most common causes is soil erosion, which can occur due to water runoff from rain, irrigation, or poorly managed drainage systems. Over time, water can wash away the soil beneath the concrete, creating voids.

Poorly designed or maintained drainage systems can contribute to soil erosion and lead to hydrostatic pressure buildup. Downspouts that direct water toward the concrete rather than away from it can go fast to erosion and lead tovoid formation. If the soil beneath the concrete is not adequately compacted, it can settle over time. It can lead to the formation of voids and potential concrete settlement.

Ignoring void space under concrete can lead to several consequences, including slab cracks, settling, concrete damage, and reduced property value. These issues often require professional void filling services and foundation repair.

The Science Behind Effective Void Filling

Effective void filling services rely onadvanced techniques and materials to restore stability to compromised structures. The process involves injecting specialized fill materials into voids beneath concrete slabs or within soil formations. Polyurethane foam void filling has emerged as a leading solution for concrete void filling. This innovative structural foam expands upon injection, conforming to the surrounding environment and providing comprehensive coverage. The foam’s expansion can be precisely controlled, ensuring accurate void filling without risking damage to nearby structures.

One of the key advantages of void fill foam is its rapid curing time, which minimizes disruptions and allows for quick project completion. The lightweight nature of the foam reduces stress on weak soils, helping to prevent further settlement. Additionally, void filling foam is moisture-resistant, ideal for areas prone to water exposure. This durability ensures long-lasting results, extending the lifespan of concrete structures and reducing the need for future repairs. The void filler foam also enhances the load-bearing capacity of the concrete, providing added concrete protection.

FAQs

What is void filling?

Void filling is the process of injecting material into empty spaces beneath concrete structures to stabilize them. This helps prevent further settling or cracking of the concrete surface. One shared method is void filling concrete, which involves using specialized materials to fill gaps and support the slab.

How do you fill a void under a house?

To fill a void under a house, you can inject expanding foam or grout to stabilize the foundation. For those looking for a hands-on approach, there are fill void under concrete slab DIY methods available. However, it’s often recommended to consult professionals to ensure the integrity of your home’s structure.

What is the best foam to fill void under concrete?

The best foam for filling voids under concrete is polyurethane foam. This material expands to fill gaps and provides strong support for the concrete slab. Many professionals use void filling foam concrete due to its durability and effectiveness.

How much does foam jacking cost?

Foam jacking typically costs between $5 and $25 per square foot, depending on the project’s complexity. The overall cost to fill void under concrete slab can vary based on the size and accessibility of the area. It’s best to get a quote from a reputable contractor for an accurate estimate.
