Gramm Barrier Systems GREENSoundBlok® system has been uniquely designed to help the barrier blend in with its surroundings.
We have designed the barrier to manufactured offsite in component parts which allows for an efficient and safe install onsite.
Once the barrier has been installed, fast growing plants such as Ivy can be planted at the base. After a short amount of time the barrier starts to be encased with plant growth, resulting in a cost-effective Living Green Barrier System.
Each panel is made of corrosion- resistant aluminium sectional frame for increased stability. The panels have a high density rockwool which provides substantial noise reductions. The GREENSounBlok® system is manufactured with a robust interlocking system for easy staking of multiple elements.
The reverse side of the panel facing away from the noise source is also high absorptive creating a double-sided absorptive barrier system. The robust element structure provides a natural appearance if the decision is made not to install plants. Gramm offer a wide range of colours on our GREENSoundBlok® system which allows for individual design.
A unique design feature of the GREENSoundBlok® barrier construction is that individual panels can be removed and replaced. Panels are not bolted, welded, or otherwise permanently fastened to each other or to the support posts (Top security fixing added if required). Should replacement be called for as a result of structural damage, no more than four workmen using ordinary hand tools will be able to do the job.
Gramms GREENSoundBlok® noise barrier system can be either set into concrete foundations or bolted down to individual concrete pads or a continuous concrete strip/pad.
a) Galvanised steel or PPC posts with baseplates can be fixed to concrete surfaces using chemfix resin anchors or cast in cradles.
b) Steel posts can be set into augered or bucket dug concrete foundations.
