The Army Corp of Engineers (ACOE) builds and manages numerous projects along the rivers and waterways of the United States. On our mightiest river, the Mississippi, the ACOE was tasked with upgrading the large siphon systems that are used to draw down the river level during flood events. To prevent catastrophic flood damage, these siphons kick on if the river is going to crest over the top of the levees.

The first thing you see when you visit the site is a massive concrete bulkhead about 30 feet tall, 8 feet thick, and over 100 feet wide. Penetrating through the bulkhead are eight 84” ductile iron pipes through which the river water is ejected if the siphon kicks on. It is at these penetrations that the ACOE was looking for some ideas.

When the bulkhead was constructed, eight large square holes were formed across the face before pouring the concrete. It is through these large square holes that the 84” diameter pipes are placed. The ACOE was looking for solutions to fill the annular space between the round pipe and the square hole.

Powerful Polymers

After consulting with New Orleans-based contractor KMH Coatings and the ACOE, it was decided that a high-density polyurethane foam would be perfect for the application. NSF-approved AP Lift 430 was selected as the go-to product. Its combination of excellent strength, yield, and bond is ideal for these kinds of structural void fill applications, but most importantly it is watertight.

Painless Procedures

KMH mobilized their polyurethane spray rig and the AP Lift 430 was sprayed into the annular space around each of the 8 pipes. AP Lift 430 is most commonly known as a first-class concrete lifting polymer but a large percentage of applications are void fills. Once the void was filled, they attempted to cut off the overspray but it proved to be too dense to cut. Instead, a disc grinder was used to sand down the polymer foam flush with the face of the concrete bulkhead.

Rapid Result

The ACOE was extremely impressed by the toughness of the product and with the minimal time that it took to install it; two days from start to finish.

Polyurethane grouting is an essential process in construction and infrastructure projects with the need to lift structures, fill voids, and stabilize soil. While polyurethane grouting has been utilized for decades, advancements in technology and technique have enabled a new level of precision and control in modern grouting applications. Innovations in polyurethane injection methods and equipment allow design and construction teams to achieve highly accurate, consistent injections for maximum strength and longevity. 

Precision is critical in polyurethane grouting applications. Inadequate filling of voids or inconsistent distribution of grout can lead to structural instability, settlement, and even collapse. Precise injections ensure that soil is saturated, voids are filled, and slabs are leveled accurately. This provides uniform load distribution and protection against shifting, vibration, and erosion. Precision also prevents wasted materials and rework due to incorrect amounts or placement of grout. 

Modern polyurethane grouting equipment and techniques enable accurate monitoring and adjustment of grout injection rates, depths, pressures, and consistency. Some examples of modern technology include: 

• Hydraulic and Electric Pumps: Modern polyurethane injection equipment includes hydraulic or electric pumps. These pumps provide precise control over pressure and flow, ensuring a more uniform injection of grout material.
• High-Pressure Injection: Modern equipment can handle high-pressure injection, making it suitable for stabilizing deep structures and addressing challenging soil conditions. High-pressure injection ensures better penetration of the polyurethane grout.
• Remote Monitoring and Data Logging: Advanced systems come with remote monitoring and data logging capabilities when necessary. Operators can monitor the injection process remotely and collect data on pressure, flow, and other parameters for quality control and documentation.
• Compact and Portable Systems: Some advanced injection grouting systems are designed to be compact and portable, making them easier to transport to job sites and set up quickly.
• Safety Features: Modern equipment includes safety features such as shut-off valves and pressure relief mechanisms to protect both operators and the equipment itself.

Modern polyurethane grouting equipment has revolutionized construction and infrastructure project challenges, offering engineers and design teams an array of precision-driven advantages. The evolution of polyurethane injection equipment, including hydraulic pumps, pneumatic pumps, and computerized control systems has empowered design teams and application technicians to achieve precise outcomes.

Carrington Woods Lake Dam is located in Baldwin County, Georgia. A consulting firm collaborating with a general contractor called in geotech specialists Atlas Structural to stabilize an abandoned below-grade culvert pipe that had deteriorated over time. The pipe ran underneath a spillway. With supporting soil migrating into it, its unstable condition threatened the integrity of the structure.

Powerful Polymer

The technicians chose single-component AP FIll 720 for the job. The deteriorating pipe was 100 feet long, and due to the circumstances at the site, grouting could only be done from one end. Getting a two-component foam 100 feet up a pipe before it cured would have been impossible. AP Fill 720, featuring a very flexible set time adjustment range with the catalyst, allows technicians to pump the material for great distances before it starts to react and cure.

Painless Procedure

AP Fill 720 does not have to be heated and only needs moisture for reaction. The crew had two electric injection pumps, one pumping AP Fill 720 with an accelerator and the other pumping water. They had 150-foot lines on each pump. Both pump lines were run through a 100-foot PVC tube. The technicians used a video camera, mounted five feet back from the end of the PVC tube, to monitor the fill. The crew pumped both water and poly in unison for a good reaction. As the pipe filled up, they slowly withdrew the PVC and continued pumping until the pipe was full. The process basically consisted of pumping, extracting the tube a foot, and repeating - until the entire 18" x 100' pipe was filled.

Rapid Result

The deteriorated pipe was completely filled and stabilized. Soil migration was stopped and the threat to the structure of the spillway above was eliminated. This job was completed in only three hours. Complete removal or filling with concrete would have taken days. In addition, concrete does not expand, so a 100% fill would have been impossible. AP Fill 720 expanded to fill 100% of the pipe. The consulting engineer and general contractor were very happy with this result.
