Frequently Asked Questions

What is the diference between regular DRICORE® Subfloor and R+?

DRICORE® Subfloor R+ has all the benefits of DRICORE® Subfloors but with more than twice the insulation so floors feel even warmer! DRICORE® Subfloor R+ has are R-value of 3.0 vs. DRICORE® Subfloors which has a R-value of 1.4.

WHY DO I NEED A SUBFLOOR?

Most basement floors, even in new homes, are damp. Concrete is a porous substance and requires air circulation. As temperatures in the basement fluctuate, it creates the perfect environment for moisture to accumulate between the underpad and concrete. This is where mold can begin to germinate which can lead to poor indoor air quality. A subfloor ensures there is an air gap between the finished floor and the concrete to help protect against moisture, mold and mildew.

WHY IS DRICORE® SUBFLOOR R+ THE BEST SUBFLOOR SYSTEM?

DRICORE® Subfloor R+ is a simple do-it-yourself solution to help you create a warm, dry, comfortable basement that is fast and easy to install. Designed with a layer of extruded polystyrene foam (EPS), DRICORE® R+ delivers an R-value of 3.0.The secondary layer of oriented strand board (OSB), provides a solid foundation that can support any type of finished floor and furniture.

HOW DO DRICORE® SUBFLOOR R+ PANELS HELP TO PREVENT MOISTURE PROBLEMS?

DRICORE® Subfloor R+ has a layer of extruded polystyrene foam (EPS) to help protect against mold and mildew production. DRICORE® Subfloor R+ has also been designed with Air Gap technology that encourages constant air flow and evaporation of surface moisture emitted from your basement concrete floor.

WHY ARE THERE SOMETIMES VARIANCES IN THE COLOR AND TEXTURE OF WOOD IN THE DRICORE® SUBFLOOR R+PANELS?

Color and texture variances are natural and not an indication of quality. Variances can be driven by several factors including; the type of trees, the geographical location of the trees and the growing conditions.

THE TONGUE AND GROOVE ARE NOT ALIGNING PERFECTLY?

Sometimes wood variances occur, in this situation manually insert the tongue into the groove by lifting the boards slightly and inserting.

HOW MUCH HEADROOM IS LOST WHEN USING DRICORE® SUBFLOOR R+ PANELS?

The DRICORE® Subfloor R+ panels are only 1″ in thickness, less than half of the height of a conventional subfloor.

CAN DRICORE® SUBFLOOR PANELS SUPPORT HEAVY OBJECTS?

DRICORE® Subfloor can support 6,642 pounds per square foot and DRICORE® Subfloor R+ can support 3,153 pounds per square foot as tested by an independent lab, so heavy furniture and equipment like pool tables, weight sets, and pianos are not a problem.s

WHAT SIZE ARE THE DRICORE® SUBFLOOR R+ PANELS?

The DRICORE® Subfloor R+ panels come in a 1″ x 23.25″ x 23.25″ format. This size was created to provide a convenient, lightweight solution that is easy to handle and maneuver when loading into basements.

IS THERE A WARRANTY?

Yes. The DRICORE® Subfloor R+ panels feature a 25 year limited warranty.

WHAT FINISHED FLOORING CAN BE INSTALLED OVER DRICORE® SUBFLOOR R+?

Add your favorite finished floor – think engineered hardwood, laminate, carpet, vinyl or ceramic tile.

CAN I CUT DRICORE® SUBFLOOR R+PANELS INSIDE THE HOUSE?

Yes, the panels cut quickly with a circular saw, jigsaw, or hand saw.

HOW LONG DOES IT TAKE TO INSTALL DRICORE® SUBFLOOR R+ PANELS?

The length of installation time will vary by the room size and complexity of room layout. An average 400 square foot basement should take 4 hours.

CAN I INSTALL IT MYSELF?

Yes, the easy-to-handle, 3/4″ x 23.5″ x 23.5″ panels are configured with a tapered tongue and groove edge making panel assembly fast and easy. Panels cut quickly with a circular saw, jigsaw, or hand saw.

HOW MANY PANELS WILL I NEED?

Estimating is easy. The total square footage of your room divided by 3.3 equals the number of panels you need. This factor includes an allowance for normal wastage and cutting around obstacles and pipes. To calculate how many panels you need.

WHAT TOOLS ARE REQUIRED?

Safety glasses, work gloves, pencil, measuring tape, carpenters square, circular saw and/or jig saw, level, hammer or rubber mallet, chalk line, taping block and pry bar are the basic tools that help to install DRICORE® subfloor panels quickly.

Please note: For protection against airborne dust particles, it is recommended to use a certified dust mask when cutting panels.

DO I GLUE THE SEAMS OR INSTALL PLASTIC ON CONCRETE BEFORE LAYING DOWN DRICORE® SUBFLOOR PANELS?

No. Gluing the panel edges is not recommended. The panels are intended to expand and contract with the seasonal temperatures of the basement. A vapour barrier over the concrete surface is not recommended. The built-in high-density polyethylene membrane is the moisture barrier on the underside of the panel, which allows incidental moisture to dry easily.

DOES DRICORE® SUBFLOOR R+ WORK ON UNEVEN CONCRETE FLOORS?

Yes. For uneven floor variances greater than 1/4″, we recommend first using a concrete self-patching compound or a similar liquid concrete patching product. For floor variances less than 1/4”, we recommend DRICORE® leveling shims.

To check for floor height variances, take a 4ft level or longer straight edge and place over the concrete surface where the installation is to take place. Raise the straight edge or level to the level line and measure the height difference between the concrete floor surface and straight edge with a measuring tape. Mark the spots on the concrete floor where liquid leveling is required and fill in as necessary.

WHERE CAN DRICORE® SUBFLOOR R+ PANELS BE INSTALLED?

DRICORE® Subfloor R+ can be installed in basements, slab-on-grade homes, garages, workshops, storage rooms, bathrooms, laundry rooms and above ground concrete floors.

CAN DRICORE® SUBFLOOR R+ PANELS BE INSTALLED IN A BATHROOM OR LAUNDRY ROOM?

Yes. When installing DRICORE® Subfloor R+ panels up to shower stalls or bathtubs, run a flexible caulking to seal the gap between the finished floor and the tub/shower unit in this area to prevent excessive moisture from seeping between the finished floor and DRICORE® Subfloor R+ panels. Continue to leave the 1/4″ spacing around the remaining perimeter edges as specified in our installation instructions.

While DRICORE® Subfloor R+ panels can carry the weight of tubs and/or shower stalls, it is recommended to install these fixtures directly over the concrete surface as to prevent exposure to leaks from plumbing or cracks in seams or fixtures to the surface of DRICORE® Subfloor R+.

See the finished flooring section for details on finished flooring installations.

CAN I INSTALL PERIMETER OR INTERIOR WALLS DIRECTLY ONTO DRICORE® SUBFLOOR R+ PANELS?

Stud walls can be set right on top of your new DRICORE® Subfloor R+. Install your 2’ X 4’ walls directly on top of the DRICORE® Subfloor R+ panels, measuring for a snug fit between the panels and ceiling. Once the walls are framed and in position, simply screw the bottom plates of the 2’ X 4’ wall to the DRICORE® Subfloor R+ panels, using 2″ wood screws.

To finish the anchoring process, we suggest pinning the bottom plate to the concrete floor either using 3″ concrete nails or self-tapping concrete fasteners. Only minimal fastening to the concrete is required. For example, on an 8-foot length of wall, you would require only two fastening points (one at both ends). Again, only minimal fastening to concrete is required. Too many fastening points breaking through the polyethylene moisture barrier may defeat the moisture resistant benefit of the DRICORE® Subfloor system.

NOTE: If you are planning to use metal studs in place of wood, the base track for the studs should be affixed to the DRICORE® Subfloor R+ panels with wood screws. Metal stud base plates should be anchored to panels every 2 feet when installing over DRICORE® Subfloor R+ panels. As above, two fasteners should penetrate the panel and go into concrete, securing the wall into place.

WHAT IF MY WALLS ARE ALREADY IN PLACE?

No problem. It is recommended when installing drywall to leave a 1/4″ gap between the concrete floor and the base of the drywall to avoid moisture contamination. Install 1/4″ spacers between the drywall and the DRICORE® Subfloor R+ panels before panel installation.

WHAT SURFACE TREATMENTS CAN BE APPLIED TO DRICORE® SUBFLOOR R+ PANELS?

Any surface treatments such as paints, stains, varnishes, and polyurethanes must be tested first for compatibility.

To apply, brush or roll on one coat of a high quality primer prior to painting, or 2-3 coats of polyurethane or varnish to the surface of DRICORE® Subfloor R+ panels. Ventilate well during this process.

WHAT FLOOR COVERINGS CAN BE INSTALLED OVER DRICORE® SUBFLOOR R+ PANELS?

Laminate, Vinyl (LVT/LVP), Carpet, Engineered Hardwood, Tile

HOW DOES AIR GET UNDERNEATH DRICORE® SUBFLOOR R+ PANELS?

The ventilation system of your home recycles air causing pressure changes throughout the house. These pressure changes force air under baseboards, cracks, expansion gaps, cavities of studs, leaks from ducting etc… Do not seal or block the 1/4″ gap in a way that prevents air from filtering underneath panels. When installing trim, it is best to raise the trim slightly above the finished flooring material, by approximately 1/8″, to help encourage airflow. For basement conditions, proper ventilation and a dehumidifier is recommended to control temperature and humidity levels.

CAN DRICORE® SUBFLOOR R+ PANELS BE INSTALLED IN A GARAGE?

Yes. Install DRICORE® Subfloor R+ panels as recommended in our instruction sheets. For garage installations, panels must end a minimum 1ft from the garage door opening. Anchor panels with Tapcon type concrete fasteners at the leading edge, install a 3/4″ transition strip to protect the edges of the panels, and anchor perimeter wall edge panels to the concrete floor every second panel.

IS FASTENING THE DRICORE® SUBFLOOR R+ PANELS TO THE CONCRETE FLOOR REQUIRED?

Not for most installations, but it is required in some installations. Below is a list of conditions that require fastening:

If a power carpet stretcher will be used to install carpeting: prevent panel uplift when stretching carpet by fastening DRICORE® Subfloor R+ panels to the concrete floor with Tapcon type concrete fasteners at perimeter edges every four feet plus one in the panel in the centre of the room.
If using DRICORE® Subfloor R+ panels for a garage or workshop where the panels will be left exposed, fasten every second panel along the perimeter wall edges to the concrete floor to prevent lateral movement or shifting with heavy equipment or use. Keep in mind that DRICORE® Subfloor R+ panels are not manufactured to be a finished floor nor left exposed to exterior weather elements.

If installing walls on top of DRICORE® Subfloor R+: use two fasteners for each 8 foot base plate, through the panels and into the concrete floor to fasten base plates.
If installing tile on the DRICORE® Subfloor R+ panels.

IS A FLOOR DRAIN NECESSARY?

No, but if you have a drain or access to clean-outs, access should be maintained, not restricted. Be sure to check with your local authority for building code recommendations before covering any basement floor drain or clean-out access.

It is not a requirement to install a basement drain prior to installing DRICORE® Subfloor R+. If you install DRICORE® Subfloor R+ panels over the drain access, cut an access opening in the panel that rests over top of the drain and install a decorative floor drain cover over top of your finished flooring.

HOW DO YOU FINISH EXPOSED PANEL EDGES AND FLOOR HEIGHT TRANSITIONS?

Transition strips for bridging floor height variations can be found in the flooring or lumber department of your local home improvement centre. Use a combination of 1″ flat moulding stock and quarter round mouldings as a transition.

CAN I USE RADIANT FLOOR HEATING SYSTEMS WITH DRICORE® SUBFLOOR R+ PANELS?

It is recommended to install radiant floor heating systems on top of the DRICORE® Subfloor panels for optimal performance. The insulating properties of DRICORE® Subfloor R+ will reduce the effectiveness of a radiant floor heating system that is installed underneath DRICORE® Subfloor R+ panels.
