Design of reinforcement geosynthetics in landfill piggyback expansion

The construction of a vertical expansion of existing waste disposal facilities (piggyback landfills) involves the use of reinforcement geosynthetics to address differential settlements and stability issues that will be reactivated under the load of the new cell.

The challenge is to guarantee the integrity of the new liner system. This paper presents the extension project of an old landfill and the main design steps to select the appropriate Geoter reinforcement geosynthetic.
