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.
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. Only minimal fastening to the concrete is required. For example, on an 8-foot length of the wall, you would require only two fastening points one at both ends.
Again, only minimal fastening to concrete is required. As above, two fasteners should penetrate the panel and go into concrete, securing the wall into place. No problem. Any surface treatments such as paints, stains, varnishes, and polyurethanes must be tested first for compatibility.
Ventilate well during this process. The ventilation system of your home recycles air causing pressure changes throughout the house. For basement conditions, proper ventilation and a dehumidifier is recommended to control temperature and humidity levels. For garage installations, panels must end a minimum 1ft from the garage door opening. Not for most installations, but it is required in some installations.
Below is a list of conditions that require fastening:. That is where the DriCore Subfloor System comes in.
DriCore comes in easily handled panels of engineered wood bonded to a rigid, moisture-resistant polyethylene sheet. The bottom of the poly sheet is molded into a grid of projections that lift the wood panel off the concrete floor about one-quarter of an inch, allowing small amounts of water to drain away. The grid system also keeps dampness away from the wooden flooring above.
The air gap also allows air to circulate between the subfloor and the concrete floor to dry up moisture. By eliminating cold moisture, the DriCore Subfloor System has been shown to raise the surface temperature of a floor by six degrees Farenheit.
The DriCore Subfloor System is easy to install. The panels fit snugly together using a tongue-and-groove system; no fasteners or glue are needed. After calculating how many panels are needed, installation is very straightforward. The DriCore Subfloor System panels to be used should be kept in the basement room where they will be installed — out of any packaging they may have around them — for at least 24 hours and probablay longer before installation.
This is to let the panels acclimatize to the temperature and humidity of the room, shrinking or swelling to the size they will maintain there. Temporary spacers one-quarter inch thick are placed along the walls of the room and around any obstacles such as columns.
The spacers will provide room for expansion of the DriCore Subfloor System due to seasonal temperature and humidity variations. Starting in one corner, DriCore Subfloor System panels are laid and locked together.
Leveling kits are provided in case there are spots in the concrete floor that are depressed. The kits can be used on depressions less than one-quarter inch; deeper depressions should be filled in with concrete or spackling compound. The DriCore Subfloor System is laid one row at a time. Each succeeding row is staggered, like a brick pattern. Panels are easily cut to fit around obstacles and into corners.
A variety of floors can be installed on top of a DriCore Subfloor System. With dry concrete and the right subfloors and vapor retarders, solid hardwood floors can be installed on slabs that are either on-grade at ground level or above-grade above ground level. If you use a product like DriCore for the subfloor , they even explicitly recommend you frame on top of their subfloor product.
They do , however, recommend you screw the framing through the subfloor into the concrete with something like 3" Tapcons spaced every 4 ft through the bottom sill of the framing. Moisture trapped under a building's walls often rots the subfloor. Left alone, the moisture eventually destroys the joists below, and the wall's plate above, the subfloor. A rotted area of the subfloor often extends under the wall.
Panels are 2' x 2' square. DRIcore estimates that squares are needed for this space. Ceramic Tile - DRIcore is designed to act as a floating subfloor. It is not recommended that ceramic tile be directly attached to DRIcore as the movement of the floating subfloor will cause tile and grout lines to crack. Select a carpet that will stand up to the concrete. Some carpet is backed with jute, which is too absorbent to use on concrete. If you 're not going to install your carpet on a subfloor, you 'll need to make sure that you 're picking a kind of fiber that will stand up to concrete's tendency to collect moisture.
Press-fit panels together with a tapping block and hammer, making sure seams are tight. Stagger panel seams similar to a brick wall pattern. The kit comes with super-thin carbon fiber and the epoxy-and-polyurethane crack injection kit, which you can also buy separately. The underside of Dricore works as a physical barrier to the moisture that would have risen up from the concrete foundation into your finished flooring.
With this technology, the water vapor only wicks up to the Dricore level, resulting in warmer and dryer floors. Versatility : You can cover Dricore subflooring products with any flooring material, including tile, carpet, laminate flooring, or engineered hardwood. You can even incorporate a type of heating system and install it directly on top of Dricore. Durability : Both models are advertised as ideal for home gyms and music rooms since Dricore is strong enough to handle gym equipment, pianos, pool tables, and other heavy furniture.
Disadvantages: Low R warmth value : While these subflooring products do reduce the coldness exuding from your concrete floor foundation, unfortunately, the R-value of Dricore is only a 1. Prices may vary depending on which store you buy them from. Installation Dricore is very easy to install thanks to the tongue-in-groove subflooring panels that lock together without using glue or tape. A square foot floor space can be done in an hour, as long as you follow these expert tips: Fix cracks on your concrete floors — Start your project by cleaning, removing debris, filling out large cracks, and drying the cement completely.
If your foundation has cracks, Dricore offers a repair kit exactly for this. If the dip is larger, you can use Dricore leveling shims instead of cement. Leveling shims are sold separately. The company recommends 1 pack of leveling shims for every 60 panels of Dricore subfloors.
Sweep, mop, and remove debris — This is a simple, yet necessary, step for installing Dricore. Acclimate your Dricore subfloors — Remove them from the box and pile them up in a safe spot in your basement. Prepare flooring spaces — Proper expansion space is essential to Dricore installation.
