Frequently Asked Questions

Typically a project will be half or less than the cost of replacement, and we offer free estimates to give you a flat rate price on your project.

Mudjacking involves lifting sunken concrete by using hydraulic pressure to pump a slurry mixture (typically dirt, sand, cement, and water) under the slab. This process fills voids beneath the concrete, restoring it to its original level without needing to replace it.

Polyfoam lifting uses a lightweight, expandable foam to raise concrete. While this method is newer, it relies on synthetic materials that can break down over time, potentially leading to a shorter lifespan compared to traditional mudjacking, which has been proven effective for over 80 years.

Mudjacking uses a natural mixture of topsoil, sand, and concrete, whereas polyfoam includes chemicals like polyurethane that must be disposed of as hazardous waste. The Environmental Protection Agency (EPA) warns that polyurethane can contain carcinogens, making disposal and long-term exposure more concerning.

While both methods provide immediate results, mudjacking tends to last longer in the pacific northwest because cement-based slurry does not degrade over time like polyurethane foam, which can break down in 5-7 years.

Yes, mudjacking is safer for both workers and homeowners. Polyurethane foam contains chemicals like toluene diisocyanate and other toxins linked to health risks, including cancer. Mudjacking’s slurry is a non-toxic, inert material.
