Highway and Bridge Geotechniques

Service Overview

GeoStructures understands the immense diversity of transportation-related infrastructures, and is dedicated to servicing the geotechnical and foundation challenges that are often connected to those projects.

Our engineers possess the breadth of experience and qualifications to handle the many geotechnical and foundation-related challenges posed by bridge and highway projects, and we have a proven record with PennDOT, DelDOT, NJDOT, SEPTA, and the Pennsylvania Turnpike Commission. Some of our most innovative engineering and design work has been incorporated into major transportation projects.

Service Offerings

Tunnels

Design and analyze tunnels, addressing geotechnical challenges to ensure stability and safety during construction and operation.

Viaducts

Develop geotechnical solutions for viaduct construction, focusing on foundation stability and load-bearing capacity in varied soil conditions.

Overpasses and Underpasses

Provide geotechnical engineering services for the design and construction of overpasses and underpasses, ensuring structural integrity and safety.

Deep Cuts

Manage geotechnical aspects of deep cuts in road construction, including slope stability and soil reinforcement to prevent landslides and erosion.

High Fill Embankments

Design and construct high fill embankments, ensuring they are stable and capable of supporting transportation infrastructure over varying terrains.

Natural Soils and Rock Slopes

Analyze and stabilize natural soil and rock slopes, preventing landslides and ensuring long-term stability for adjacent transportation infrastructures.

Steep Reinforced Slopes

Design and implement reinforced slopes, using geosynthetics and other materials to stabilize steep inclines and support roadway construction.

Earth Retaining Systems

Develop and install earth retaining systems, such as retaining walls and anchored systems, to support highways and bridges in challenging terrains.

Shoring

Provide shoring solutions for temporary support during construction of bridges, tunnels, and other transportation structures, ensuring worker safety and structural stability.

Buried Culverts

Design and inspect buried culverts, ensuring proper drainage and structural integrity under roadways and bridges.
