MASH TL5 System in North America

Foundationless

Free-standing, modular barrier engineered to simplify construction.
Reduces associated design risks and speeds up the noise wall installation portion of a project.
Shallow anchoring depth requires only 6.69 in (17 cm) for anchoring and can easily be removed if ever required.
Minimizes underground utility disruption

Crash-Tested Reliability

Proven to withstand rigorous MASH TL-5 testing, ensuring safety performance transportation owners can rely on.
Additional concrete beam is incorporated to protect the wall system where truck contact occurs, providing additional protection for the noise barrier panels and ensuring durability during collisions.

Maximum Noise Reduction

Double-sided absorptive panels effectively reduce noise and eliminate reverberation.
Minimal distance to the noise source as an effective noise mitigation strategy.

Space Efficiency

Integrated safety and noise barrier structure for efficient land use.

Precast Concrete

Delivers the long-term durability and service life required for today’s highways and roadways.
