Geotextile for Egyptian archaeological site

I am seeking recommendations for a geotextile that would be suitable
for use on an archaeological site in northwest Sinai, Egypt.

The main structures at Tell el-Borg are two partially overlapping
mud brick forts that were constructed circa 1500-1150 BC. Only the
lowest courses of mud brick have survived. However there are also
well preserved remains of fosses or moats around the forts. The
walls of the fosses/moats consist of foundation courses of fired
brick on top of which there are courses of mud brick.

Descriptions and photographs of the fosses/moats and the mud brick
walls of the forts can be seen on the project's website:
<URL:http://www.tellelborg.org>. In the Reports section of the
website, the 2004 Preliminary Report has photographs integrated with
the text.

At the end of each season of excavation the trenches containing the
mud brick walls of the forts and the fosses/moats are backfilled.
The archaeologists are currently using plastic sheeting as an
interface between the backfill and the archaeological remains.
Because the plastic sheeting does not allow moisture transfer we
would prefer to use an appropriate type of geotextile.

If possible we would like to purchase the geotextile from an
Egyptian distributor.
