ENGINEER
The Challenges
EarthTech evaluates project-specific demands and tailors each retaining wall solution around engineering risk, site access, soil behavior, and construction sequencing.
Extreme Loading
Narrow Wedge Reinforcement
Seismic & Extreme Weather
Differential Settlement
Extreme Loading
Bridge structures, highways, rail corridors, and industrial facilities create significant surcharge (240kPa) demands on retaining systems. EarthTech offers reliable retaining wall solutions for extreme loads while maintaining long-term structural performance.
Narrow Wedge Reinforcement
EarthTech turns sheet pile, soil nail, gravity, or soft ground into innovative MSE retaining wall systems in confined space or existing slope while maintaining constructability and structural reliability.
Seismic & Extreme Weather
Reliable mechanical connection enhances retaining systems to perform under seismic activity, flooding, freeze-thaw cycles, and extreme weather conditions. Solutions are developed to improve resilience, durability, and long-term infrastructure reliability.
Differential Settlement
Soft ground and varying soil behavior can lead to differential settlement and structural movement. EarthTech applies flexible reinforced soil systems and staged retaining wall solutions to accommodate settlement while protecting long-term performance.
BUILDABLE RESPONSE
EarthTech Solutions
These solutions are developed in response to the engineering challenges above. Each option connects a specific site constraint to a buildable retaining wall strategy, helping the project move from risk assessment to practical construction.
Extreme Loading
