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).

■Seal gaps between DELTA®-FL and any posts or penetrations with low expansion spray foam
to prevent the passage of water vapor into living area.
■Access to floor drains and clean-outs must be maintained. Cut DELTA®-FL around drains or
clean-outs. Seal DELTA®-FL with low expansion spray foam (see Detail 4).
Carpet, Vinyl, Hardwood, or Other Floor Covering Requiring Rigid Substrate
■Place 4’ x 8’ sheets of minimum 7/16” OSB/ Plywood sheets over DELTA®-FL.
■Pre-drill the wood sheets and the concrete according to the fastening pattern (see Detail 4).
■Apply a small amount of silicone caulking on the thread of the fasteners and into
the pre-drilled hole of the wood sheets prior to installing the Tapcon® screws.
■Install 8 (eight) Tapcon® screws per sheet (see Detail 5).
■Inspect the wood sheets for areas with bounce, tapping, or squeaks. Add additional fasteners
where necessary.
■Some hardwood floors are nailed to the substrate. When these types of hardwood floors
are installed, ensure that the fasteners do not penetrate the DELTA®-FL. Note that some
hardwood floors may not be recommended for below grade use. Check with your flooring
manufacturer.
■Install final floor as per manufacturer’s recommendations.
Floating Laminate and Engineered Wood-Flooring Installations
■Place recommended underlayment foam over DELTA®-FL as indicated by the laminate/
engineered wood floor manufacturer.
■Install the laminate/engineered wood flooring system as recommended by
manufacturer (see Detail 6).
General Notes
■Transitions: Consider any transitions from one finished flooring system to another (i.e.
laminate to carpet). The elevation difference may affect your final installation.
■Material allowance: Always allow 10% to 15% extra material to accommodate doorways,
cutouts and waste.
■Always follow local Building Code Requirements whenever building/renovating.
Added Warmth and Comfort
■DELTA®-FL acts as a vapor barrier. An additional vapor barrier is not required on the concrete
floor.
■Extruded or expanded rigid insulation boards can be installed over the DELTA®-FL prior to the
installation of the finished flooring.
Limitations
■Product is not desinged for pernament UV exposure. Always cover as soon as possible.
Load Considerations
■DELTA®-FL features high compressive strength. Typical household items like refrigerators,
billiards tables and furniture can be placed onto the finished flooring without compromising
the DELTA®-FL.
Disposal of Waste
■DELTA®-FL is made from environmentally friendly HDPE.
■Waste can be recycled where facilities allow.
