Innovative Use of GCL's Saves Money & Time

Engineers at Cleveland Hopkins Airport were faced with several challenges in constructing a 76 acre EPA mandated de-icing facility, including poor soil and a short construction season. Since the airport engineers were experienced in landfill construction, they decided to try an approach utilizing geosynthetics that is typically used for landfill liner systems.

Geosynthetic Clay Liners (GCLs) were chosen for the liner system designed to protect the environment from the excess de-icing fluid because of low hydraulic conductivity, good chemical resistance properties, self-healing characteristics, and ease and speed of installation.

Because of the aggressive construction schedule, much of the installation took place during winter months, when typical used construction materials, such as asphalt and geomembranes, could not be used. In addition, the use of the EasyRoller™ GCL deployment system by CETCO allowed for GCL installation rates at up to 45,000 square feet per hour.

By using geosynthetic materials, at least 100,000 cubic yards of fill material and millions of dollars were saved according to Robert Evans, airport planning and engineering chief, and the project was completed on time and on budget.
