Healthy Spillways, Safe Communities

Assess and Sustain Spillways with EagleLIFT’s Scan and Repair Process

Red-flags are being raised throughout California regarding the health of its spillways and flood control structures. The recent drought has left our spillways largely untested and, as we are finding out, that doesn’t mean they haven’t been compromised.
The task seems daunting in such a short timeline, but it may not be as complex as it seems.

EagleLIFT’s Scan and Repair approach is a cost-effective method for identifying issues and then repairing the problems quickly and cost-effectively. Firstly, detecting the problem is the main focus. For this we utilize a Ground Penetrating Radar (GPR) system to scan the entire spillway and determine if there are any voids present. If voids are present, we then fill the voids and stabilize the structure with our polymer injection application.

DSCF9836EagleLIFT specializes in restoring the weight-bearing capacity of soils using the patented URETEK Deep Injection Process. This method of repair is done by injecting a high-density structural polyurethane into the problem zones in a specially designed
injection pattern that fills any present voids and densifies and repairs the soil for its designed use.

In addition to void detection and soil repair, EagleLIFT is also a class “A” General Contractor, so if any additional engineering or repair methods are required, we can bring on the contractor as needed to complete the rehabilitation. We also have
strong bonding capability, safety performance and extensive experience on public works applications.

With Rains and Floods Comes Settlement and Decisions

We have had the Northern California and Nevada regions in our thoughts and prayers as flooding has ravaged the areas causing substantial damage to personal and public property and structures. As the water recedes, there may be structural damage that may need to be addressed immediately to ensure further damage does not occur due to settlement or further soil erosion.

As water moves, soil moves, it is a fundamental concept of erosion. Moving or shifting soil causes base support soils to erode and leads to structural settlement, voids, or shifting structures. In these cases, it is usually best to address the issue as fast as possible as the soil weight-bearing capacity needs should be restored.

Affected structures vary, from residential and commercial buildings to sewer and roadway infrastructure. There are many ways to deal with these issues in a time and cost-efficient manner. Here are some solutions for your needs.

Determining the cause of your problem

You must ensure that the cause of your problems is known.  Without this, any proposed solution for your structure may be inadequate or too costly for the repair.  If you are going to invest the money in repairing your property, then you should be sure the repair is successful and cost effective.

Soil Repair

If the soil supporting the structure was compromised, any present voids need to be filled and the soil’s weight-bearing capacity re-established. Void filling and soil stabilization can be done using the EagleLIFT polymer injection process. Once injected, the polymer will actively seek out any voids below the structure and throughout the soil.   The polymer will then begin to expand and densify, restoring or improving the weight-bearing capacity of the soil. The soil repair process is used for a variety of applications including roadway repair, embankment stabilization, dam repair and levee reinforcement and infrastructure sealing.

Structural realignment

EagleLIFT offers two forms of structural lifting and realignment, utilizing the polymer injection process or through the use of helical and push piers.  If a good option, EagleLIFT’s polymer injection process is by far the most cost-effective solution for lifting.  A proprietary injection pattern is used to allow the polymer’s expansive qualities provide upward, which can result in foundation or structural realignment.

Roadway Repair

Flooding and soil saturation can cause roadways, culverts and bridge approach slabs to sink or become unstable, due to the base soil being undermined by washout or infiltration of the soil into manholes, culverts, and lateral lines.  With the use of the EagleLIFT polymer injection application, the soils are stabilized, the infrastructure is sealed, and the structures roadway or bridge approach slab can be leveled and restored to use.  The application is quick and cost-effective and can be completed on an emergency basis.

Outfall, Emergency Levee and Dam repair

Water control structures are needed to hold back the floods and if undermined can cause the waters to impact areas they were designed to protect.  The Polymer injection application can be used to stabilize these structures by binding the soils and increasing their weight-bearing capacity.  This can be used to help the soils from being undermined due to washout.

Conclusion

The EagleLIFT team is here to help you combat the issues that are being created by these floods.  If you need any help, please contact Derek Berthelot at derekb@eaglelifting.com.

Southern California Drainage Channel Repair

EagleLIFT Provides Drainage Channel Repair at Riverside College from Water Intrusion

Drainage Channel Repair included Lifting and Leveling of structure and joint sealing against water intrusion

In the southwestern United States, Drainage channels are an important infrastructure tool for ensuring heavy rain events do not cause flash floods and subsequent property damage.  Maintaining these systems is essential to make sure that communities are protected and public works systems, such as roadways, are not interrupted due to washout or pooling water. Riverside City College, located in Riverside, CA, was experiencing problems with a portion of its drainage channel and contacted EagleLIFT to perform the drainage channel repair.

Riverside Drainage Channel Repair

Riverside City College (RCC) had approximately 450 linear feet of its drainage channel that had become undermined by water that was traveling underneath the concrete panels.  The water began to washout the base support soils of the channel, causing voids and settlement along the channel’s bottom and sidewalls.  The College was seeking a cost-effective solution to extend the life of the drainage structure and to avoid the cost of rip and replace.

EagleLIFT recommended and was contracted to perform the URETEK Method to stabilize the panels, fill the voids, and seal the joints to restore the water flow over the channel.  The URETEK Method is a process whereby an industrial grade, high-density polyurethane is injected through 5/8” holes directly into the weak soil zones to stabilize, compact and densify the area.  Once injected, the polymer initially moves throughout the injection point in liquid form, aggressively seeking voids and the path of least resistance, and then it begins to expand throughout the soil media and densify the soil.

Southern California Drainage Channel Repair
EagleLIFT utilized a 4ft injection pattern along the bottom of the drainage structure and half way up the sidewalls.  The pattern design was intended to provide consistent void fill and to adjoin the material to provide effective undersealing of the concrete panels.  Since the URETEK polymers are hydrophobic, the material would push out any sitting water and protect the panels against future water intrusion.

EagleLIFT worked as subcontractor under Three Peaks Construction, who was contracted to install an epoxy overlay over certain areas of the channel after the voids were filled. EagleLIFT coordinated all activities with Three Peaks Construction and RCC maintenance staff to ensure work did not interfere with College operations.

Results

All voids under the areas of concern were filled with material usage coming in at 25% under budget.  RCC was able to use the cost savings for additional repair projects that they did not anticipate having the funding to complete.  The project was also completed without any interruption to RCC’s operations.
