Our roadways in the United States are a massively important piece of infrastructure. These highways make up the paths that employees use to get to work and that family members use to make their way home for holidays. When these roads become plagued with potholes and uneven transition slabs, it not only makes a bumpy ride, but creates risks too. Cars can get damaged, trailer hitches can come off trucks, and the structural damage can worsen if left unchecked.
This is where contractors like NORTEX come in.
For this Throwback Thursday, we're looking back at a major highway rehabilitation project in the Houston area. Portions of I-10, the 610 Loop, I-59, and I-69 were experiencing potholes, settled roadway and bridge approach slabs, and dips caused by conditions including soil subsidence, vibration, washout, and poor base soils.
NORTEX identified key problem areas and developed injection plans based on the needs at each location. NCFI-4RH geotechnical polyurethane was injected beneath the roadway to fill voids, stabilize underlying soils, and lift and realign settled slabs.
Across more than 150 locations, over half a million pounds of polyurethane were installed. Work was performed during evening hours to help minimize disruption to the highway system, and the fast-curing polyurethane allowed treated areas to return to traffic within minutes of installation.
Projects like this demonstrate how polyurethane injection can help contractors address roadway settlement while keeping heavily traveled infrastructure moving.
