Concrete slabs naturally settle over time and will eventually need repair work done. Slab jacking used to be the only way to fix these slabs and you had to wait at least 24 hours to be able to use them again after repair. Currently, many property owners are turning to polyurethane foam for concrete raising so they can use their slabs immediately. This concrete service method has numerous other advantages as well. Here are five benefits to raising concrete with polyurethane foam.
Cement raising with polyurethane foam requires a few small holes to be drilled into the concrete. A concrete crack repair service contractor can drill these holes and pipe the foam efficiently without a mess. Slab jacking requires larger holes to be drilled and slurry to be mixed on-site. This can become messy. The extra cleanup can add to the labor costs for the work.
The expansion capability of the foam plus the drilling of smaller holes creates a process with minimal disruption. Slab jacking requires traffic to be avoided on the concrete slabs for at least 24 hours. With polyurethane foam, the slabs can be used immediately. If homeowners need their concrete driveway completely replaced, they’ll have to avoid using the new driveway for at least a month while it cures. Repairing the driveway instead with a foam injection allows them to use the driveway right away.
Polyurethane foam is environmentally friendly. It consists of renewable and recycled materials that won’t rot or pollute the soil. Because of the foam’s longevity, it can keep more concrete slabs out of the landfills.
High Strength Capacity
Polyurethane foam has a high strength capacity. Between 2,000 to 4,000 pounds per square foot can be supported by polyurethane foam. You can drive vehicles and heavy equipment over the repaired slab within 30 minutes of the concrete crack filler work being completed.
A polyurethane foam injection is generally far less expensive than replacing concrete. The costs you’ll pay for foam concrete leveling will vary depending on the project and how much material is required. Slab jacking is also much cheaper than replacing concrete and requires cheaper material than foam injections. However, the concrete service labor costs will offset those savings in being cheaper than the foam overall.
Polyurethane foam injections have many advantages for filling concrete voids and raising slabs. Before you consider having your driveway replaced, schedule a consultation and inspection with a concrete service provider. You’ll be able to save yourself time and money.
