Engineer: Fred Laker of ICOS. Contractor: Decorton Retaining.
These two noise and blast barriers installations were constructed by Decorton Retaining. Both have Terraforce gravity walls at a steep angle facing the buildings to be protected, backed with an earth berm, level top and sloping away at 45º.
1. Noise and blast barrier at an airport
2. Blast barrier next to a school adjacent to an American embassy
The barriers are between 2m and 5m high and serve to protect two vulnerable buildings while at the same time resulting in significantly reduced noise levels.
Both are to be planted with hardy ground covers where soil erosion could develop into a problem. For aesthetic reasons, plants will be established on the wall, facing the one building as well.
