Propex 1071 - 10oz Environmental Geotextile.

Propex 1071 meets (or exceeds) the specifications most commonly detailed in Canada for geotextiles used in the construction of new radon gas prevention systems for under concrete slabs. This product is commonly used directly below the 15mil radon sheet membrane barrier, and above the gas permeable aggregate, to protect the sheet membrane from damage caused by sharp aggregates. The 1071 is also sometimes used below the gas permeable aggregate to prevent contamination with fines from the subsoil.

Propex 1071 is commonly used under all sorts of geo-membrane liner applications, including ponds, to add a cushioning layer between the substrate and the liner. This cushioning layer will help prevent angular rocks from puncturing your liner.
