Installation

Before installing the Kerabit Foundation Wall Membrane, it is necessary to install the Kerabit Pato/Radon Strip at the joint of the foundation wall and the footing. Kerabit foundation wall membranes are installed with the studs against the foundation wall, fastened at the top and finished with an edge trim. 

Kerabit foundation wall membranes must be covered carefully and as soon as possible after installation to prevent damage during construction.

 

Storage

Rolls must be stored upright, protected against direct sunlight, at a temperature below 45 °C.
