The Quick Installation Guide

Preparation

  • Determine the number of panels and leveling kits for the installation.
  • Clean the concrete floor and install the temporary 1/4″ spacers against the perimeter walls.

Installation

  • In your selected starting corner, lay the first panel with the tongue sides against the temporary 1/4″ spacers.
  • Press-fit panels together with a tapping block and hammer, making sure seams are tight.
  • Stagger panel seams similar to a brick wall pattern. Complete one row at a time across the room allowing for a 1/4″ gap around walls and room obstructions.
  • Use DRIcore leveling shims for any floor variations less than 1/4″.

Finish with flooring

  • Ideal for carpet, laminate, engineered hardwood, tile and vinyl flooring.
  • For best results, run a dehumidifier to maintain relative humidity between 30 — 50% and regulate the room temperature to 21C (70F).

Preparation

Making Interior walls

  • An interior stud wall can be set right on top of your new DRIcore Subfloor and is in fact, the preferred method of installation. Install your 2X4 frame directly on top of the subfloor, measuring for a «snug» fit between the subfloor and ceiling.
  • Once the frame is in position, simply screw the bottom plates of the 2X4 frame to the DRIcore panels, using 2″ wood screws. To finish the anchoring process, we suggest fastening the bottom plate to the concrete floor using either 3″ concrete nails or concrete fasteners.
  • Only minimal fastening to the concrete is required. For example, for every 8′ length of base plate, install only two concrete anchors. 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 5/8″ wood screws as a maximum. Metal stud base plates should be anchored in concrete every 2′ when installing over DRIcore Subfloor R+ panels.

Carpet

To prevent panel uplift when stretching carpet, fasten DRIcore Subfloor R+ panels to the concrete floor with flat head ¼» x 2 ¼» or 2 ¾» concrete fasteners every other panel at perimeter edges and one in the panel in the centre of the room. Use a 3/16″ x 4 1/2″ drill bit to bore the holes. Install tack strips on top of the DRIcore Subfloor R+ panels around the perimeter of the room, to hold the carpet down. Install pad and carpet. Do not glue the underpad or carpet directly to the DRIcore Subfloor R+ panels.

Laminate

Install the floor manufacturer’s foam pad and finished flooring on top of the DRIcore Subfloor R+ panels. The installation of a continuous vapour barrier on top of DRIcore Subfloor is permitted as long as it is not sealed to the perimeter wall. Only remove the ¼» wall spacers after the laminate floor has been installed.

NOTE that the installation of a continuous vapour barrier on top of DRIcore Subfloor R+ is permitted as long as it is not sealed to the perimeter wall. Only remove the 1/4” wall spacers until after the laminate floor has been installed.

Engineered/Solid Hardwood

Follow the wood manufacturer’s guidelines as to what can be installed at or above grade and below grade. The National Wood Flooring Association defines below grade as any part of a concrete floor that is 4” or more below the soil level. Before installing glue-down or nail-down floors a 3/8″ plywood underlayment should be fastened to DRIcore Subfloor R+ using 18 gauge ¾» or 7/8″ narrow crown staples. When installing nail-down floors test a piece of the finished floor to make sure the fastener does not puncture the plastic membrane. Remove the ¼» wall spacers after the wood flooring has been installed. NOTE: Do not glue engineered hardwood floors directly to DRIcore panels.

Ceramic Tile

Fasten each DRIcore Subfloor R+ panel with five, flat head and countersunk, concrete fasteners to the concrete floor to prevent movement or shifting of the finished ceramic tile floor. We recommend one in each of the four corners and one in the centre of the panel. Use flat head ¼» x 2 ¼» or 2 ¾» concrete fasteners and a 3/16″ x 4 1/2″ drill bit to bore the holes. Next install an approved tile underlayment over DRIcore Subfloor R+ making sure you follow their installation guidelines for installing over a wood subfloor. NOTE: DRIcore Subfloor R+ must lay perfectly stable. A sound recommendation would be to have one person walk the floor. Step heavy or bounce, with another looking for vertical movement of panels. If there is noticeable movement, mark the areas in question with an X and insert another concrete fastener. Please note that we also do not recommend gluing underlayments or other wood flooring materials to DRIcore Subfloor R+.

Sheet Vinyl and Vinyl Tiles

¼» plywood underlayment approved for use with sheet vinyl or adhesive-backed vinyl tiles should be fastened to the DRIcore Subfloor R+ panels. We do not recommend lauan plywood as an underlayment. Use ¾» flooring fasteners that do not penetrate the moisture barrier on the underside of the DRIcore Subfloor R+ panels. Do not glue the plywood underlayment to DRIcore Subfloor R+ panels. Do not glue adhesive-backed vinyl tiles directly to the DRIcore Subfloor R+ panels. Glue the vinyl floor to the plywood underlayment according to the vinyl manufacturer’s installation instructions. Only remove the ¼» wall spacers after the vinyl floor has been installed.

Height Transitions:

Wood transition or reducing strips that are available in the floor and molding departments should be used to bridge floor height variances.

Exterior Door Transitions:

Here are a few ideas for installing DRIcore Subfloor R+ up to an existing exterior door area that, when combined with the finished flooring material, is higher than the door threshold:

  • Install ceramic tile, in a small section large enough to allow for the door opening, as a transition up to the DRIcore Subfloor R+ panels and the finished floor.
  • For steel exterior doors that cannot be trimmed, raise the door header, if possible, to account for the heights of DRIcore Subfloor R+ and the finished floor.
  • For wood exterior doors, trim the door and raise the door threshold to accommodate for the new floor height.

The success of any finished floor depends on the characteristics and the quality of the materials used and the nature of the installation. DRIcore (AGT Products Inc.) does not extend any express or implied warranties to finished floors installed over its DRIcore product. Click here for complete warranty details. Special Health Protection Information — Personal Protective Equipment: Wear goggles or safety glasses, work gloves and approved dust mask when cutting panels. Use an approved respirator in dusty or enclosed environments. Ventilation — Minimize airborne wood dust by always cutting panels in a well-ventilated space. Promptly clean up any accumulations of wood dust and do not use blow-down or other practices which may generate high dust concentrations when cutting panels. We’re here to help.
