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).
