Concrete Repair for Schools

Not only is sunken concrete in schools unsightly, but it also poses a trip hazard for staff, students, and parents. Once concrete voids form underneath the slab, the damage gets worse over time. However, there are many concrete repair options available, but which method will address the underlying problem?

A sunken concrete slab can now easily be transformed into a safe concrete slab. At Polyjacking.com we use polyjacking or foamjacking. In this process, a high-density polyurethane foam fills voids and cavities underneath the slab. This method of concrete repair strengthens weak and loose soils, preventing future settlement.

If the concrete slab in your school has become uneven, various repair methods are more effective than concrete replacement. Rather than shutting down areas of the school, you can use polyjacking, which is a quick and effective way to fix uneven concrete. We can lift, level, and stabilize your concrete back to normal within minutes without disrupting the school.

The concrete leveling process is simple, yet effective. It involves the following steps:

1. Small holes (5/8") are drilled through the concrete slab.
2. Polyurethane foam is pumped through the holes, filling voids and cavities underneath the slab. As the foam expands, it lifts and levels the slab back to normal.
3. The drill holes are patched.
4. Polyurethane foam cures within 15 minutes, allowing the concrete to be ready the same day. Mudjacking and other methods can take days to cure.

Because there is minimal downtime with polyjacking, it is ideal for schools, cafeterias, and universities. Polyjacking can be used to fix sunken concrete stairs, walkways, sidewalks, floors, and other concrete surfaces for schools in the St. Louis and Kansas City area. Contact us today for a free estimate.
