Petra is a famous archaeological site in Jordan’s southwestern desert. Dating to around 300 B.C., it was the capital of the Nabatean Kingdom. Accessed via a narrow canyon called Al Siq, it contains tombs & temples carved into pink sandstone cliffs, earning its nickname, the Rose City. Petra Gate is a symbol of Jordan, as well as Jordan’s most visited tourist attraction, along the way to the Petra Gate, is the EQLA’A TIWAL road which requires a road widening & a new retaining wall. The client wanted an alternative & durable retaining wall solution that will look similar to the existing masonry wall, which in turn blends well with the lime stone. At the same time, the retaining wall has to be environmental friendly (being a UNESCO heritage location) and economical. Among the various retaining wall options available, MSE walls are found to be the most economical, in comparison to conventional retaining walls like concrete walls or masonry wall. However, the popular type of MSE walls in Jordan till date were concrete facia, which doesn’t comply to the requirement of matching with surroundings. Thus, the consultant recommended Maccaferri Middle East for a better retaining wall solution which meets the requirements of the project’s end client.
