Implications of Improper Installation or failure of the system:

Moisture can easily penetrate a foundation wall or floor without proper installation of a moisture barrier. Issues such as; concrete deterioration, water damage, mould and mildew, and damage to partition wall studs can arise from the moisture that penetrates the walls and floor. Insulation's thermal effectiveness is greatly reduced when insulation becomes damp or wet.

The Simple Truth: The moisture barrier protects the wall cavity from moisture that escapes from the concrete walls or slab.
