ASL has recently worked on the Crossrail project.  We have been requested to provide verification of the installation of gas protection membranes to ancillary buildings forming part of the construction project.  ASL has worked closely with the site operator and qualified professional gas membrane installers to complete a difficult element of the development.  In completing this project ASL staff have gained valuable experience of major projects and furthered our portfolio of gas membrane verification and validation projects throughout the UK.
