Relative Humidity meets the SaniDry

Thursday, October 19th, 2017 by Autumn Quick

Did you know that mold can grow in your finished basement despite not having a plumbing or groundwater leak? This is because even though your basement may look dry, feel dry and smell dry, the air itself is not dry. All mold needs to actually begin to grow is Relative Humidity. High Relative Humidity is mostly caused by water vapor coming through the concrete. There are of course terms for these events. Wicking ( also called "capillary action") occurs when water, in liquid form, soaks through porous materials much like concrete, when it gets wet on one side, the water soaks through the concrete onto the other side. This is most common in block walls, but it can also happen to floors and other types of foundation walls.

Vapor Transmission is another term that is used. This is when water in vapor form comes through the porous concrete and evaporates off of the surface and into the air. A gas, such as water vapor, will move from more to less, so even if the ground is not saturated, its nearly 100% humidity all the time and that water vapor is moving through the concrete into your basement. This is exactly why you will notice that the air feels damp and heavy, much like in mid summer after a rainstorm, it's humid outside, the same applies to your basement. The problem with High humidity levels is, if you put material against the surface of the floor or walls, you end up trapping the water vapor there. Moisture ends up building up to levels that mold can begin to grow. Vapor transmission and condensation is the reasons why mold grows in basements that do not experience a groundwater leak when it rains.

Mold needs mainly four things to grow. Mold needs spores, which is the seeds of mold, to begin growing. Mold also needs food, which is the organic material you have supplied in your basement. This includes the wooden studs in your basement, the wood paneling, the carpet material, the ceiling tiles with the paper facing on te back, you name it, there is an organic buffet down in your basement. Mold also needs water or high humidity, which is also plenty in your basement. Mold also needs a certain temperature, mainly between 32° and 110° F. When eliminating mold infestations, you want to control the Relative Humidity in your basement, that's where Tri-State Total Basement Finishing steps in.

Dehumidifiers are the right solution to this problem, but not just any dehumidifier, the SaniDry Dehumidifier is what your basement needs. It's the only machine that will keep your finished basement dry and odor free. The SaniDry is a high-capacity, high-efficiency dehumidification system, with air filtration in a single unit. The SaniDry takes up to 100 pints (47.3 L) of water per day out of your basement air, whilst using the same energy as a 40 pint (18.9 L) dehumidifier. It also filters particles out of the air to less than an incredible two microns in size, which is smaller than any mold spore or dust mite dropping.

The SaniDry has such a powerful blower which moves that dry air out into and around your basement space. This dry air then in turn dries your building materials and basement contents, which makes that damp smell and damp feeling go away. Just another amazing thing about the SaniDry Dehumidifier is that you will never have to empty any buckets because it automatically drains into either your WaterGuard or sump pump system or a condensation pump. The SaniDry is Energy Star Rated, a rare achievement for a dehumidification system. A huge benefit about this product is that you do't have to keep it located in the space that you are trying to dry. You can locate it into a utility room and duct the wet air in and dry air out to the main room of your basement.
