What happens when you don’t excavate for two years? – reviewing excavation area protection measures
Caitlin R. O’Grady
Every season, we spend a lot of time and effort implementing measures to protect excavation areas between field seasons. This includes “wrapping” architecture, scarps and baulks with geotextile, a water permeable cloth made from thermally bonded non-woven polypropylene fibers. The geotextile protects these features minimizing erosion and plant growth. Following wrapping, we use rocks and “dirt bags” to ensure complete protection.
However, long term exposure to plants, animals and the elements between seasons cause the geotextile to degrade, which makes it necessary to “unwrap” and “rewrap” architecture and excavation areas.
Luckily, I work with a great team of people that make this process smooth – even on the two hottest days of the season! 46° and 47° C (that’s 115° and 117° F!) thus far.
