MASH TL5 System in North America
Features & Benefits
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.
