Deep Polyurethane Foam Injection for Soil Stabilization and Concrete Foundation Repair


At Cleveland Concrete Leveling, we take pride in using the most innovative and effective services for soil stabilization and concrete foundation repair work. Our revolutionary technique of Deep Polyurethane Foam Injection has actually shown to be a game-changer in the building market, providing unrivaled stability, durability, and cost-effectiveness. In this comprehensive guide, we will look into the details of our groundbreaking method, its advantages, and why it surpasses conventional techniques. So, let’s dive in!

Understanding Soil Stabilization

Prior to we delve into the specifics of Deep Polyurethane Foam Injection, it’s important to grasp the principle of soil stabilization. In building jobs, the foundation plays an important function in supporting structures and distributing loads. Soil motion, settlement, or weak bearing capacities can lead to foundation failures. Soil stabilization is the process of boosting the engineering properties of soil, making it more stable and trusted for supporting structures.

The Challenges of Traditional Methods

Historically, soil stabilization and concrete structure repair relied on techniques like cement grouting, chemical injection, and excavation. While these techniques supplied some level of improvement, they had their constraints. Cement grouting, for instance, was prone to uneven distribution and needed comprehensive excavation, triggering disturbances to the website. Chemical injections, on the other hand, had ecological concerns and differing degrees of success.

The Innovation: Deep Polyurethane Foam Injection

In reaction to the restrictions of traditional methods, Deep Polyurethane Foam Injection became a revolutionary option. Our cutting-edge approach includes injecting a high-density polyurethane foam mixture deep into the soil or underneath the structure. The foam quickly expands and fills voids, condensing loose soil, and increasing load-bearing capacity.

Advantages of Deep Polyurethane Foam Injection

1. Exceptional Strength and Stability

The injected polyurethane foam develops a robust, stable, and uniform structure support group. Its expansive properties ensure that even hard-to-reach locations are effectively filled, leaving no room for settlement or motion.

2. Very Little Site Disruption

Unlike traditional methods that need extensive excavation, Deep Polyurethane Foam Injection minimizes site disruptions. The procedure includes little injection holes, leaving the surrounding area intact and lowering project timelines.

3. Water and Chemical Resistance

Polyurethane foam is highly resistant to water and chemicals, making it a perfect service for supporting soil and foundations in different environments, consisting of marine or chemically-contaminated websites.

4. Light-weight and Non-Intrusive

The foam’s light-weight nature applies very little stress on the soil and structure. It does not include excessive weight, ensuring there is no additional burden on the existing structure.

5. Lasting Results

Deep polyurethane foam injection offers long-lasting outcomes, preventing soil settlement and foundation problems for several years to come. It uses exceptional worth for money, as it gets rid of the requirement for frequent repairs and upkeep.

Applications of Deep Polyurethane Foam Injection

The adaptability of Deep Polyurethane Foam Injection makes it relevant to various building and construction circumstances:

1. Residential Projects

From little houses to big estates, our foam injection innovation can stabilize the soil and repair work structure issues for any home.

2. Commercial and Industrial Buildings

Storage facilities, factories, offices, and other industrial structures can gain from the stability and resilience offered by polyurethane foam injection.

3. Transport Infrastructure

Highways, bridges, and railways frequently face foundation obstacles. Deep polyurethane foam injection supplies a reputable service for such important infrastructure.

4. Community and Public Facilities

Public facilities like schools, health centers, and government buildings can take advantage of the lasting stability provided by our innovative strategy.

The Deep Polyurethane Foam Injection Process

Polyurethane foam injection, also known as polyjacking, is a modern and efficient technique used to level uneven concrete slabs. This method involves injecting a high-density polyurethane foam beneath the concrete to lift and stabilize it. Here’s a detailed description of how the process works:

Step-by-Step Process

  1. Assessment:

    • Before any repair work begins, a thorough assessment of the existing concrete slab is conducted. This includes examining the extent and cause of the damage, as well as the soil conditions around the slab. This step ensures that the application of the polyurethane foam is suitable for the specific situation
  2. Preparation:

    • The preparation phase involves drilling small, strategically placed holes into the affected concrete area. These holes are typically dime-sized and are drilled around cracks or voids beneath the concrete, which are key indicators of where lifting is needed
  3. Injection:

    • Injection ports are installed into the drilled holes. A specialized two-part polyurethane foam mixture is then injected through these ports. The foam travels into the voids beneath the concrete slab and begins to expand. This expansion exerts upward pressure, lifting the concrete back to its original level. The amount of foam and the pressure of injection are carefully monitored to ensure precise lifting and to avoid over-raising the slab.
  4. Curing:

    • The polyurethane foam requires time to cure and set, which usually takes about 15 minutes. During this process, the foam hardens, forming a solid and stable base for the concrete. This quick curing time allows the area to be used almost immediately after the repair is complete.
  5. Patching and Cleanup:

    • After the foam has cured, the drilled holes are patched using a compound that closely matches the color of the concrete slab. Any remaining debris or mess is cleaned up, restoring the surrounding area to its original state. This ensures that the site looks as close to its original condition as possible.

Benefits of Polyurethane Foam Injection

  • Minimal Invasiveness: The small size of the injection holes means that the aesthetic impact on the concrete surface is minimal, preserving the appearance of the concrete structure.
  • Efficiency: The rapid curing time of polyurethane foam means that areas undergoing repair are accessible much sooner compared to traditional methods, reducing inconvenience and downtime.
  • Durability: Polyurethane foam is highly durable and can withstand heavy loads and extreme weather conditions, making it an ideal solution for leveling concrete slabs that have suffered from settling due to soil erosion or other environmental factors.
  • Precision: The foam’s expansive properties allow it to fill voids and lift and level the concrete effectively, ensuring a uniform and stable surface.

Polyurethane foam injection has revolutionized the field of concrete repair and maintenance, offering a quick, efficient, and long-lasting solution for leveling uneven concrete slabs.
