|The Reinforced Earth®
technology can also be used to form a double-sided structure to raise the
height of an existing earthen dam, and in doing so increase the spillway
capacity and consequently the retaining volume of the dam.
The evenly distributed loads throughout the Reinforced Earth® abutment and the ability to increase the stability of existing embankments mean that Reinforced Earth® is a cost-effective method well suited to construction on top of earth dams.
