The Costco Headquarters and National Distribution Centre in Kemps Creek, NSW, required a high performance sound barrier to protect the peace and quiet of surrounding residents. The client required a durable solution that offered maximum acoustic capabilities, an aesthetically-pleasing finish and compatibility with a pre-existing retaining wall.
ModularWalls’ AcoustiMax75 acoustic wall panels within their industrial-grade GuardianWall system fit the client’s design brief perfectly. Universal beams and proprietary UB infills were utilised to create the noise barrier, reaching 5m high and spanning almost 800m in length. The wall was installed behind the keystone block gravity retaining wall, using void forming pier liners into which the universal beam posts were installed and concreted into place.
The proprietary AcoustiMax panel achieves an Rw rating of 28, whilst the premium residential aesthetics provide local residents a visually appealing backdrop that ensures their peace will remain undisturbed by the Costco development.
