Monarflex Monarflow 27
Monarflow 27 Passive Venting is a high strength, pre-formed geo-composite designed to trap and remove gases from sub-surface layers. It consists of a HDPE core hot welded to a geotextile filter and is available in rolls 915mm wide x 50m in length.
Passive Venting: Basic Principles
-
Gas Resistant Membrane - Prevent gas entering building when natural forces are insufficient to cause dilution and dispersion of gas
-
High Permeability Ventilation Layer - Hazardous gases migrate into ventilation layer and are diluted and dispersed to atmosphere by air flow via side vents
-
Adequate Ventilation Void - To store gas at safe levels for no wind periods
