GRS-IBS Bridges

Geosynthetic Reinforced Soil-Integrated Bridge Systems (GRS-IBS) offers unique advantages, particularly in the construction of small bridges. Construction costs are typically 25 to 60 percent lower than conventional construction methods.

GRS - An engineered fill of closely spaced alternating layers of compacted granular fill material and fabric sheets of geosynthetic reinforcement.

IBS - A fast, cost-effective method of bridge support that blends the roadway into the superstructure using GRS technology. This creates a simple, joint-less interface between the bridge and the roadway alleviating the "bump at the bridge" problem caused by uneven settlement between the bridge and the approaching roadway.
