The paper illustrates the use of an adhesive-geocomposite system for a concrete dam upstream facing rehabilitation in Italy. Careful planning and coordination between the owner, the consultant and the contractor, followed by preliminary on-site tests and laboratory tests, resulted in proposing a rehabilitation of the upstream facing and an overall waterproofing of the dam, based on a geocomposite, for111ed by different layers of polyvinylcloride (PVC) geomembrane and one layer of needle-pu,rched nonwoven polyester (PET) geotextile.
The technological solutions for the application of the geocomposite-adhesive system are furthermore described.
