A membrane has been delivered to the full extent to the construction site of New Safe Confinement. This membrane is intended to completely seal the NSC Arch. The membrane itself was designed and manufactured of polyurethane exclusively by CNIM, a French company. In course of design all potentially possible types of deformation were taken into regard: expanding by 55% from the initial size to withstand winds that can reach up to 300 km/hour. Moreover, the membrane body has special incorporated pieces which prevent any tearing.
The membrane width makes 150 cm and the length of one section reaches 16 m. The complete membrane will utilize about 2 thousand meters of polyurethane fabric.
The membrane will be soon installed on the sealing anchors which have been mounted on Shelter, process building and other structures which are adjacent to the arch. Once the membrane has been installed the arch interior space will be isolated from the environment.
