Preparing the Concrete for Installation

 

The concrete floor and foundation walls should be dry, free of large cracks, excessive  

 

  moisture, leaks and flooding. DELTA®-FL is not meant to replace good foundation design or    
 maintenance.

 

Any pre-existing unsound or moisture-sensitive flooring materials should be removed prior to  

   installation of DELTA®-FL.

 

The floor should be as level as possible.  Remove any bumps or ridges. In areas with  

 

  depressions greater than ¼”, self-leveling compound should be used.

 

Thoroughly clean and vacuum the concrete floor. 

 

Ensure floor area is solid and free of mold and fungi.

 

Optional: In case of uneven floors, installing a layer of needle-punched geotextile    

 

  (landscaping fabric) underneath the DELTA®-FL can reduce the potential for clicking noises.

Installation

 

Beginning at the longest straight wall, roll out the DELTA®-FL, dimple side down and  

 

  cup side up. 

 

DELTA®-FL should be installed as tightly as possible to all walls (see Detail 1).

 

For applications with stud walls already in place, lift the protective moisture barrier at the  

 

  bottom and place over top of DELTA®-FL (see Detail 2a).

 

For applications with stud walls already in place that do not have a protective moisture  

 

  barrier underneath or applications directly against the foundation wall, seal the gap between  

   DELTA®-FL and bottom plate or wall with low expansion spray foam (see Detail 2b).   

 

For applications without stud walls already in place, non-load bearing stud walls may be  

 

  constructed on top of DELTA®-FL. Load-bearing walls should not be placed on 

  top of DELTA®-FL.  

 

End laps and side laps shall be placed tightly to the adjacent roll of DELTA®-FL. Do not overlap  

  or interlock the dimples. Seal all end laps and side laps with DELTA®-MOISTUREPROOF TAPE    

  (see Detail 3).
