Application

The barrier can be positioned above or below a solid concrete ground floor slab or above a precast suspended segmental ground floor system (e.g. beam and block floor).
Suitable for use in all types of buildings to prevent the ingress of harmful levels of ground gases e.g. methane, carbon dioxide and radon.
The barrier can also be used as a high performance radon membrane and/or damp proof membrane.
The product is not intended for use where there is a risk of hydrostatic pressure.
