Vehicle restraint systems and noise barrier walls normally are considered separately. Therefore, more space is required and the efficiency of noise reduction is reduced. Gramm Barriers has shown that compromises are no longer necessary and com-bines those two systems to one CE-certified solution, the COMBISoundBlok® series.
The integrated noise barrier COMBISoundBlok® is designed as a free-standing, T-shaped wall element, with the New Jersey profiled safety barriers sitting on its traffic-facing footplate.
The COMBISoundBlok® integrated noise barrier is designed as a free-standing, T-shaped wall element. The profiled safety barrier sits on its traffic-facing footplate. Both system parts act as independent chains linked to each other via the proven GRAMM couplings.
It is not only the barrier we develop, for GRAMM it is the holistic solution. Saving money and time is on our task list – right after saving lives.
The restraint system respectively noise barrier COMBISoundBlok® acts as safeguarding for the verge on motorways and dual carriageways. Due to the noise absorbing material laminated to the surface of the wall, it additionally works as a high-grade sound insula ion system.
Tested safety is what you expect from a modern vehicle restraint system. Tested absorption and sound insulation is what you require from a noise barrier. The DB LSW series combines both in the most versatile way. The COMBISoundBlok® is designed for the roadside H2 | W4 | ASI B.
For GRAMM, the CE-certification is obligatory, no matter if it is concerning EN 1317 safety or EN 14388 acoustics.
Concrete footings or piled foundations are not required.
