Learn moreEKHO’s MASH TL-4 Ground Mounted Noise Barrier is a modular, ground-mounted absorptive noise barrier system. The MASH TL-4 Ground Mounted Noise Barrier is host to an integrated precast concrete crash railing and an inertial impact panel to stabilize box trucks in collisions. Our system has been successfully tested under MASH (Manual for Assessing Safety Hardware) TL-4 conditions, proving its ability to hold up when needed most and not fail in real world scenarios.

Noise + Safety
A robust precast TL-4 barrier solution that combines tested impact performance with fast installation and dependable, long-term protection.
EKHO's double sided absorptive panels reduce noise concerns and reverberation.
Drop in barrier sections and stacking panels
Panels come in a variety of architectural textures, patterns and colours.
Precast concrete barrier provides another layer of safety. While inertial impact panel above protects the noise barrier and stabilizes box trucks.
Durisol® MASH TL-4 System is a modular, absorptive, ground-mounted noise barrier system just like the TL-3 system – however, it has been tested to MASH TL-4 conditions and includes an integrated impact panel for trucks.
1100mm single slope precast concrete barriers are placed between steel posts, connected in sequence with our proprietary load transfer system.
Integral inertial impact panel placed at 10’ elevation to ensure protection of the wall from soft portions of the truck.
W-10 (W250) post ground mounted post design.
Overall crash tested height of noise barrier system installation above pavement was 17.3’ (5.273m), however, designs can vary.
