If a high water table is a problem in your home or basement, you are probably looking for a flooring solution that won’t be damaged by the infiltrating water. Dricore Subfloor System may be the solution for you. It doesn’t resolve all of the problems associated with high water tables and water problems inside the home or office, but it takes care of some of them.

Many homeowners want a finished basement, complete with hardwood floors, wooden column wraps, and elegant wood furniture. These things are fine as long as no water gets into the basement. If it does, then the hardwood floor and possibly everything resting on it is kaput.

The trick is to give water someplace to go besides into the expensive hardwood flooring and the furniture it supports. 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. Carpet, floating hardwood panels, and floating tiles are popular floorings. Fixed tile installations can be tricky. The DriCore Subfloor System is a floating panel system, and the movement of these panels can crack the grout in a fix tile floor. However, there have been successful installations that used a one-quarter inch underlayment and half inch cement board suitable for ceramic tile installation. It is important to use fasteners that do not penetrate the Dricore Subfloor System panel to pierce the polyethylene sheet.

The DriCore Subfloor System will not protect against a catastrophic flood. But it will prevent creeping damage due to small amounts of moisture, and provide a much warmer, more comfortable basement floor. It also doesn’t prevent mold problems, due to high moisture.
