The Reventazón Dam is a concrete-face rock-fill dam built on the Reventazón River in the Limón province of Costa Rica. Inaugurated at the end of 2016, it is the largest power station in the country, with a total capacity of 305 MW. The project has become a model of environmental integration, featuring passages for wildlife.

For this major dam project, Dextra Latin America continuously supplied and supported contractor ICE from 2010 to 2016. Dextra provided its Rolltec rebar splicing solution, couplers, and machinery. Rolltec is the most popular rebar splicing solution in Latin America, offering a competitive alternative to lap splices.

The rebar preparation is supported by a unique, lightweight machine operated by a single worker. The Rolltec machine is relatively easy to transport and convenient to install, even in remote locations such as dam construction sites.

Rolltec splices were used inside the water tunnels, installed on bent rebar. For this type of application, the straight bar must first be threaded and then bent. During the bending operation, a coupler may be temporarily fitted onto the bar end to protect the thread.

Dextra Rolltec couplers were also installed in the tall structure (130 meters high) as a method for splicing rebar vertically.
