The Challenge
The main issue needing attention was the leaking of the stormwater infrastructure system which was ultimately threatening the state of the runway slabs.
The Solution
Use high-density polyurethane injections to fill voids, stabilize soils, and safely seal 800 linear feet of storm drain while ensuring proper flow and structural integrity.
The Impact
EagleLIFT efficiently filled voids around culverts, ensuring cost-effective repairs that will prolong the lifespan of the storm-water infrastructure at a busy California airport.
Location: San Diego, California
Project Type: Public Works
Repair Type: Stormwater Rehab & Soil Stabilization
The Challenge
Repair leaking 30-inch storm drain.
The main issue needing attention was the leaking of the storm-water infrastructure system which was ultimately threatening the state of the runway slabs.
There were two main objectives within this specific project. Firstly, to leak-seal the underground infrastructure with our high-density polyurethane resin from within the storm drains, which ranged from 30-inches to 60-inches in diameter. Secondly, to fill the voids located around the infrastructure and perform soil stabilization to prevent further subsidence at the surface level and to the runway itself.

The Solution
Leak-seal 800 linear feet of storm drain and inject 5 manholes with polyurethane grout.
EagleLIFT utilized a polymer injection process that comprised of a two-part, hydro-insensitive grout with the goal of filling each and every void while simultaneously displacing any standing water. The process that was executed involved the Groundworks crew injecting high-density polyurethane directly into the water, which reacts flawlessly in H20, and reaches total compressive strength in the same amount of time as when it is not submerged in water. Once the seal was complete, the crew removed any outcroppings to ensure that the flow of the pipe was not compromised.
Due to the nature of this repair, we utilized our Confined Space Contractors in order to leak seal 800 linear feet of a 30-inch storm drain in a safe manner. Groundworks also had a rescue team on standby as a safety precaution. This was all completed in conjunction with injecting five separate manholes with polyurethane grout for soil-stabilization and leak-sealing purposes.
The Impact
Prolonged lifespan of stormwater infrastructure.
As with every repair, Groundworks developed a time-efficient and methodical approach to this project due to the business of this main California airport. Each void around the culverts that had developed over the years was filled completely. The process was extremely cost-effective and will certainly maintain, as well as prolong the lifespan of the underground storm-water infrastructure.
