What is Polyurethane and why is it ideal for concrete lifting and leveling services

Polyurethane: The Ideal Solution for Concrete Lifting and Leveling Services


As time passes, concrete surfaces can experience settling, sinking, and unevenness due to factors like soil erosion, moisture content, and inadequate compaction. To address these issues effectively and ensure the restoration of concrete structures, property owners often seek durable and long-lasting solutions. In recent years, polyurethane has emerged as a popular choice for concrete lifting and leveling services. This versatile material is renowned for its strength, flexibility, and durability. In this blog, we will explore into the characteristics of polyurethane and explain why it is the ideal solution for concrete repair needs.

Understanding Polyurethane:

Polyurethane is a synthetic polymer produced by combining diisocyanates with polyols. It can be manufactured in various forms, including foam, elastomers, and coatings, making it highly adaptable for different applications. In the context of concrete lifting and leveling, polyurethane foam is injected beneath sunken concrete slabs to raise them back to their original position.

Advantages of Polyurethane for Concrete Lifting and Leveling:

  1. Lightweight and Minimally Disruptive:

Polyurethane foam is lightweight compared to traditional concrete or mudjacking materials. Its low weight reduces the stress on the underlying soil, preventing further settlement. Additionally, the injection process involves small, strategically placed holes, minimizing disruptions to the surrounding area.

  1. High Load-Bearing Capacity:

Despite its lightweight nature, polyurethane foam has an impressive load-bearing capacity. It can effectively support heavy concrete structures and evenly distribute weight, ensuring long-term stability and preventing future settling.

  1. Precise and Controlled Application:

Polyurethane foam is injected in a liquid state, enabling precise and controlled application. As the foam expands and fills voids, it gradually lifts the concrete slab to the desired level. This controlled process ensures accurate results, reduces the chances of over-lifting, and minimizes damage to the surrounding area.

  1. Rapid Cure Time and Minimal Downtime:

Polyurethane foam cures rapidly, often within minutes of injection. This quick-setting characteristic minimizes downtime, allowing property owners to resume regular activities shortly after the repair. Furthermore, the fast cure time helps mitigate weather-related delays, as the foam is not significantly affected by temperature fluctuations.

  1. Water and Chemical Resistance:

Polyurethane foam exhibits exceptional resistance to water and chemicals, making it suitable for both interior and exterior concrete repairs. By creating a moisture barrier, the foam prevents future damage caused by water infiltration. It also offers protection against corrosive substances like salts and acids, ensuring the longevity of the repaired concrete.

  1. Longevity and Durability:

Polyurethane foam is renowned for its long-lasting performance. Once injected, it retains its shape, stability, and strength over time. The foam resists erosion, compression, and degradation, ensuring that the repaired concrete remains level and functional for many years.


Polyurethane foam has revolutionized the concrete lifting and leveling industry by providing a reliable, efficient, and cost-effective solution. Its lightweight yet high load-bearing capacity, precise application, rapid cure time, water and chemical resistance, as well as its long-term durability, make it the ideal choice for concrete repair needs.
