FAQ

Customers frequently ask

Is foamjacking a permanent solution for sunken concrete slabs?

Absolutely, foamjacking provides a long-lasting solution for concrete lifting and leveling. Our foam is impervious to water, chemicals, insects, rodents or erosion and as long as the substrate continues to perform the polyurethane will last indeönitely. Our estimator and technician will make suggestions as to how to maintain your repair as well as the other concrete surfaces around your home.

Is polyurethane foam environmentally friendly and safe?

Yes, polyurethane foam used for concrete lifting is eco-friendly and safe for both humans and the environment. It is non-toxic and free from harmful substances, making it a responsible choice for concrete leveling.

Are there any limitations or situations where foamjacking may not be appropriate?

While foamjacking is highly effective for most concrete leveling needs, there may be instances where extensive structural damage or irreparable concrete requires alternative solutions. In such cases, we will assess and recommend the best course of action.

How strong is the foam? Can it lift really heavy slabs?

The foam is very strong and has a rating of 75-80 PSI. Meaning a cubic inch of foam can hold up 75-80 lbs of weight. But it’s really the expansion process that lifts the concrete. The high PSI ensures the lift will last. Even the heaviest load is no match for our high-density foam.

Is it possible to lift the concrete too much?

With over 1500 jobs under our technicians’ belts, there’s no need to worry about overlifting. In addition, the injection process is done slowly and methodically. A few inches of lift can take several minutes and numerous injections. Each injection takes only 10-15 seconds to fully expand and additional injections are made in 20-25 second intervals allowing time for maximum expansion before the next injection is made. In other words, the foam is injected slowly and methodically to avoid an over lift.

How long does the foam Lifting process take?

Your repair will typically take anywhere from a few hours to a day, depending of course on the amount of concrete being repaired. Your concrete is ready to use again as soon as our team drives away!

Will my landscaping be disturbed by your process?

No. Our truck and trailer is parked in the street or your driveway and a light weight, exible hose is pulled to the affected area where the lift is needed. The foam is applied through holes drilled in the surface of the concrete and not from the side, so none of your landscaping is disturbed in the process.

What are the benefits of foamjacking over traditional mudjacking?

Foamjacking offers several advantages over mudjacking for concrete lifting and leveling, but these are the top 3 reasons:
‍
1) Polyurethane Foam is Longer Lasting: Our foam is impervious to water and erosion, and will not deteriorate over time. Limestone slurry can be susceptible to erosion and deterioration over time when exposed to water and weather conditions.
‍
2) Strength and Lightweight Nature of Polyurethane Foam: Polyurethane foam used in foam lifting is lightweight yet incredibly strong. In contrast, limestone slurry is heavy, adding additional weight to an already compromised base.
‍
3) Precision and Control: Polyurethane foam lifting offers precise and controlled lifting due to its expansive properties. Foam injection can be carefully controlled, allowing for accurate leveling adjustments and minimizing the risk of over-lifting. Limestone slurry, on the other hand, might not provide the same level of precision, potentially resulting in uneven lifting or further damage, especially around pools and slabs pinned next to your foundation.

Is foamjacking a noisy or disruptive process?

No, foamjacking is a relatively quiet and non-disruptive process compared to some other construction activities. We prioritize minimizing any inconveniences for our customers and their neighbors during the concrete lifting process.
