Whether planning for residential areas built near highways, railways or industrial facilities, noise and vibratory disturbance can be mitigated. Our engineered and manufactured noise barriers are widely used to mitigate these nuisances.<\/p>\n<\/div>
Several parameters come into play when building a noise barrier:<\/p>\n
These parameters define the materials and barrier configuration required to absorb or deflect noise. Terre Arm\u00e9e offers two types of noise barriers that can be either ground-mounted or supported on deep foundations.<\/p>\n
FanWall\u2122 is a proven and economical free-standing sound barrier and is used in residential, commercial and industrial sites.<\/p>\n
It is a free-standing noise barrier made of full-height or stacked rotatable concrete panels, assembled using a tensioned wire rope connection. FanWall\u2122 can be installed on a concrete leveling pad or on a simple gravel pad. Panels are placed based on the desired layout, then connected with tensioned strands. The wall is backfilled along the footing with a shallow gravel footing (normally a 30cm to 60cm depth on both sides).<\/p>\n
FanWall\u2122 presents several benefits. The rotatable, interlocking panel joint has sufficient residual angular rotation and vertical movement to eliminate the damaging effects of expansion, contraction, and frost heave which is common to other long-wall alternatives. Other benefits:<\/p>\n
Our innovative StresTec\u2122 post-and-panel noise barrier solution is focused on the mechanical connection of the precast posts to the shallow, low-depth shafts.<\/p>\n
Posts are situated in cannisters and can be temporarily supported through light prestressing as an option. Our method allows flexibility to make adjustments in terms of roadway offset, post spacing and post alignment. Once all adjustments are complete, the embedded cannisters are grouted via a pre-positioned integrated grout pump (optional) assuring proper post positioning and stabilization.<\/p>\n
The innovation eliminates the need for external bracing, and allows for alignment adjustments. The segmental stacked panels are set between the posts in a fashion common for post-and-panel construction.<\/p>\n
Benefits of the StresTec\u2122 post-and-panel noise walls:<\/p>\n
Terre Arm\u00e9e also offers bunds and embankments as an option for noise mitigation. These structures are quick to build and have proven their efficiency for noise mitigation applications. Our solutions are a combination of soil reinforcement that can be geosynthetic and facing allowing for vegetation to grow and providing a natural vegetated appearance to the structure.<\/p>\n
Terre Arm\u00e9e has developed customized sound absorbing precast barriers made of panels with a reinforced concrete core and a sound absorbing face oriented towards the noise source. Designers will define the right geometry and select specific materials given the project’s requirements and characteristics such as ribbed porous concrete or wood concrete.<\/p>\n<\/div><\/div><\/div>
Our flagship technique, Reinforced Earth\u00ae, is based on the principle of the friction between soil and reinforcements creating a permanent and predictable bond. At the origin of all mechanically stabilized earth (MSE) walls on the market today, we are continuously perfecting this ingenious technique.<\/span>
