Transportation infrastructure

Important Resources for Civilizations Economy

Transportation infrastructure is among the most important economic resources of civilization. Billions of dollars are spent on structures to support the movement of goods, services, and people throughout the United States. Highways, roads, bridges, railroads, drainage culverts, and more are expensive to build. Designers, and builders must ensure that highways, roads, bridges, railroads, drainage culverts, and more last for more than 100 years of service life. 

JET Filter’s maintainable weep hole solution can help extend the service life of retaining structures that support our transportation infrastructure.

Weep Hole Filter Installed In Bridge Abutment - Transportation Infrastructure

Bridge Abutments

In the US, there are more than 600,000 bridges. These bridges cross over spaces like water, roads, train tracks, and culverts that are at least 10 feet wide. Each bridge has two ends that are held up by things called abutments. These abutments are very important for keeping the bridge safe.

JET Filter’s maintainable weep hole filters can be used to drain water from behind abutments. This relieves the water pressure and keeps key bridge components dry to minimize rust and failure.

Watersheds let water flow through ditches, creeks, streams, and rivers. Most of these waterways have small amounts of water. But roads still go over them. People often use box culverts to let water go under the road.

Maintainable weep hole filters are used to relieve pressure off culvert walls, ceilings, and even culvert floors.

Retaining wall & Wing Wall with Maintainable Weep Hole Filters

Retaining Walls & Wing Walls

Retaining walls and wing walls help support roads and the soil around them. The walls keep the road and soil in place, whether they’re higher or lower than the ground. Wing walls mainly help hold up the sides of a bridge or culvert opening. 

Retaining walls support roadways, entrance ramps, and exit ramps when they are higher or lower to the ground.

Hydrostatic pressure builds up behind retaining walls and wing walls and must be drained.  Maintainable Weep hole filters are the most cost-effective solution to extend a wall’s service life.
