Foundation Repair: Concrete Lifting vs Piering

There are a lot of alternatives when it comes to Foundation Repair Near Me, and figuring out which one is best might be an overwhelming task. As a result, we’ve written this essay in the hopes of giving you an unbiased assessment of two concrete lifting technologies: foam concrete lifting and foundation piering. We hope that after reading this, you’ll be better informed and more confident in determining which technique, or mix of technologies, is appropriate for your foundation repair job.

Concrete Lifting with Polyurethane

To begin, we’ll start with polyurethane concrete lifting to ensure that you have a fundamental understanding of each technology. Because of its speed, cost-effectiveness, and relative cleanliness, concrete lifting with polyurethane injection has quickly become one of the most popular solutions for foundation repair. It works by injecting polyurethane into a hole drilled into or adjacent to the concrete slab using specialized mixing equipment.

The polyurethane begins to become confined in the injection zone once it has filled the vacant areas. During confinement, the polyurethane becomes extremely dense, eventually causing lifting pressure in the weakest section of your concrete slab. If there is enough material, polyurethane can produce enough compressive strength and density to lift your slab back to level and grade.

Piering Fundamentals

Helical and push piers are the two types of foundation piers available. Both of these techniques rely on deep, dense soils to generate enough torque or tension to pull the vehicle higher. 

The contractor anchors the helical pier to the building foundation before twisting the system into the ground with an auger. The torque will produce tension against the pier and help push the foundation higher until the helix reaches soil depths capable of providing enough torque resistance against the pier. 

The piers can then be positioned against a bracket on the Slab Foundation Fix and hydraulically pulled down to elevate the slab upward.

Foundation Piering vs. Polyurethane Concrete Lifting

When it comes to price, polyurethane concrete lifting is by far the most affordable option for minor to moderate repairs. The catch here is that polyurethane isn’t always the answer. Polyurethane concrete lifting may not be a viable solution if your structure is experiencing severe settling.

Piering systems provide longer warranties and provide more direct measurable outcomes than polyurethane systems when it comes to lifting pressures and stability. However, when it comes to costs, this is a given. When it comes to raising garages, interior footers, walkways, and driveways, as well as significantly strengthening loose and unconsolidated soils, polyurethane injection is a reliable solution. As a result, the best course of action is to assess the complexity of your project and determine which option is most appropriate.

Capacity of Lift: Foundation Piering vs. Polyurethane Concrete Lifting

Piering is the most reliable and has the largest lifting capacity on a typical base. Piering can reach deep into tight soils or bedrock to lift your foundation. Because of the density, the piers can be quite strong. Piers aren’t always the best solution, though. The use of piers on the internal slabs of many huge buildings is tricky. Buildings with no inside footers or piers on the inner supports that are difficult to install are examples. For lifting or stabilizing these inner slabs, polyurethane might be a very reliable solution. Piers have been utilized to lift the external footers in many cases, with polyurethane injection used to lift the internal portions.

Foundation Piering vs. Polyurethane Concrete Lifting

When weighing these two options, time is crucial. Injecting polyurethane is a quick fix.

CONCLUSION

Piercing and polyurethane each have their own set of benefits and drawbacks. The best option will be determined by your project’s requirements and specific conditions. In order to evaluate which is the best answer for your needs, you should speak with an expert foundation contractor or an engineer.
