Geotextile vs Polyethylene

Polyethylene is just a protection layer for the water proofing to protect it from the protection screed that is laid on it!

Geotextile is an anti slipping separation layer between the blinding concrete and the waterproofing laid above the blinding concrete.

Polyethylene sheets have no function below blinding.

That’s what I know, if anyone has more, please let us know 🙂
