The secondary noise transmission path blockage was necessary and hence the Lastro® Wall C bearing was designed and manufactured and installed between brickwork walls and concrete slabs. These slabs are extremely robust and reliable. These are additionally designed to withstand the devastating effects of an earthquake without any additional support given to the components. The quality of life of buildings can be increased by using these tiles because these can give so much more strength to the walls on installation. The products are specified under the Swiss standards of SIA 181:2006. Conventional methods can not achieve such standards but the LASTO®WALL C delivers high standards. In conditions that are exacting our products deliver them with highest of performances. They are used to block noise transmission in pipeworks and constructions.
