What Are the Differences Between Mudjacking and Foam Injection (Polyjacking)?

There are a lot of similarities between these methods. They are both less expensive than concrete replacement and much quicker. Both use a similar technique of “jacking” up the existing concrete by pumping a material underneath the concrete slab. Here’s a summary of how they differ:

	Mudjacking	Foam Injection /Polyjacking
The Process	Drill holes into sunken concrete and pump a natural mix of agricultural products (portland cement, lime, water) to raise the concrete.	Drill holes into sunken concrete and inject polyurethane foam (similar to the foam in your couch cushions). The foam expands, raising the concrete.
Installation Hole Size	Pool Ball Size (2½ inch), patched with concrete.	Dime Size (⅝ inch), patched with concrete.
Cure Time	24 hours until fully cured. Can be walked on the same day.	Within 30 minutes.
Clean Up	No disruption to to landscaping. Water is used to clean up the area.	No disruption to landscaping. Minimal clean up.
