Mudjacking vs. Polyjacking: The Science Behind Concrete Lifting

What is Concrete Lifting?

Concrete lifting, also known as slab lifting or slabjacking, is a procedure designed to raise and level sunken concrete slabs. In regions like St. Louis, with its fluctuating temperatures and occasional flooding, ground shifts can cause concrete surfaces like driveways, sidewalks, and patios to sink. Instead of the expensive and time-consuming task of replacing the entire slab, concrete lifting offers a quicker and cost-effective alternative.

The Process of Mudjacking

Mudjacking, a practice with decades of history in St. Louis, involves pumping a mixture of water, soil, sand, and cement underneath the sunken slab. This slurry fills voids, stabilizes the soil, and elevates the concrete to its original position.

Benefits:

• Cost-effective.
• Utilizes natural materials, reducing environmental impact.
• Tried and tested, with many satisfied customers throughout St. Louis and nearby areas.

Drawbacks:

• Heavier than polyurethane, potentially leading to further soil compression.
• Requires larger holes in the concrete for injection.

The Process of Polyjacking

Polyjacking is a more recent addition to the concrete lifting family. Instead of a mud slurry, this method uses high-density polyurethane foam. When injected beneath the concrete, the foam expands, filling voids and lifting the slab.

Benefits:

• Lightweight, reducing the risk of further soil compression.
• Requires smaller injection holes, leading to a more aesthetic finish.
• Sets and cures faster, allowing for quicker use of the treated area.

Drawbacks:

• Typically more expensive than mudjacking.
• Chemical-based, raising potential environmental concerns.

Comparison of Mudjacking vs. Polyjacking

When St. Louis residents weigh the benefits of mudjacking against polyjacking, several factors come into play. Cost is a significant consideration; mudjacking usually comes out as the more affordable option. However, the speed and minimal invasiveness of polyjacking, combined with its lighter weight, make it a favorable choice for many, especially for larger commercial areas in St. Louis. Both methods have proven effective in addressing sunken concrete; the choice often boils down to budget, environmental preferences, and specific site needs.

Case Studies

1. Historic St. Louis Home: A century-old residence in St. Louis had a sunken patio that was causing water to pool near the foundation. Given the age and aesthetics, the homeowner chose mudjacking to preserve the traditional feel, and because the environmental component was essential to them.

2. St. Louis Commercial Plaza: A shopping plaza faced liability issues due to uneven walkways. Opting for polyjacking, the business owners appreciated the swift cure time, allowing shoppers to use the pathways almost immediately post-treatment.
