The use of special floors has reduced the impact of heavy rains in Peru's premier tourist attraction, Machu Picchu, said Machu Picchu National Archaeological Park Head Fernando Astete.
This special material had been successfully placed in different parts of the Inca citadel
over six years.
It has also served as a path for thousands of tourists who visit the archaeological site every day.
According to Astete, using this material has been beneficial in this case; otherwise, the Incan site would have sunk up to 15 centimeters into the ground.
The expert believes heavy rains constitute the main threat affecting the ancient city.
For this reason, he highlighted the drainage system —put in place by the Incas— and the new constructions, which together allow rainwater to flow out.
This system is placed on a leaning surface so that water can drain out of the facilities, thus preventing serious harm.
