■
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.
