This is probably the most frequently asked question we get from our customers. The truth is it can come into the crawlspace in various ways but it always starts from above... the rain. From there:
1: In heavy or long consistent rain, lawns can become saturated and so many customers believe the answer is doing exterior french drains. While french drains are good for slowing down water that is coming downhill, heavy rain spreads out beyond and under french drains. With the footing of a foundation anywhere from 3ft below the surface of the exterior dirt line and a french drain sitting typically 1-2' below ground level, this does little to stop the water.
2: Bad Rain Drains. A roof takes on an average of 623 gallons of water per sq ft during rainfall. You can imagine how much falls during a heavy downpour. So, if your downspouts are not sufficiently moving the rain well away from your property, that water will saturate the area around your foundation and flood your crawlspace. While a proper drainage system and sump pump can help, the best way to handle downspouts is to extend the downspouts under ground to a safe distance away from the foundation.
3: Water Tables. If you live in an area with high water tables, as they rise, so will the water in your crawlspace. If you have a stream or pond nearby you probably have high water tables but even without an obvious water source, some areas can suffer from an underground springs that will cause the same issue.
It depends, if you have a vented crawlspace, then it is not advisable. A vented crawl space is open to the elements and has a high risk for mold, pests, and high humidity all of which can damage your stored items.
However, with our crawlspace encapsulation, you can have a controlled environment that can make the space usable for storage. Our full encapsulation will include a layer of TerraBlock, providing a layer of insulation over the dirt floor, also making it more comfortable to move around on. A CleanSpace vapor barrier is then secured over it, this is a 20 Mil woven barrier backed with a twenty-five-year warranty against tears and rips while keeping the water out. The foundation walls are insulated and air sealed, and every vent is sealed up. As a final piece, a SaniDry dehumidifier is installed to keep the humidity levels under control. All of these work together to make a crawlspace ready to be used for storage if wanted!
Keeping the relative humidity down is the key to reducing odors and preventing mold. A SaniDry Dehumidifier air system is specially deigned for cool environments to protect your home all year. If you already have a SaniDry unit, your service technician will service it during your annual maintenance. If you don't already have one, your technician can install one for you.
There are a number of ways to temporarily fix a wet crawlspace, but only one way to provide a long term solution. A crawlspace encapsulation will provide a solution backed with warranties, installed by seasoned foreman. This process will properly insulate the space, divert all groundwater safely away from the homes foundation, block out external elements, and control humidity levels to ensure mold and mildew cannot take hold. Give us a call and we will send someone out to your home for free, to do an inspection and tell you exactly how this solution will help your crawlspace water issues be resolved.
If you use your basement for storage, and little white spots are appearing on these items, there is a water issue present. Those little spots and water mold, even if pooling water isn't apparent, high humidity or moisture must be present, creating an ideal space for mold to grow. To protect this space in your home, then your basement should be waterproofed, and the humidity levels need to be controlled. With a basement waterproofing solution suited to your home's needs, mold and mildew will be a thing of the past, and your home will be dry and healthy.
An UltraSump is a secondary battery operated pump that can be installed in the same sump hole as your primary pump. It has a secondary switch, a special 120 amp battery and a smart charging system. If you already have one, your service technician will service it during the annual maintenance if you don't, your technician can install one for you.
The actual definition of hydrostatic pressure is “the force exerted by water when it’s at rest.” It’s evident in the name: “hydro,” meaning water; “static,” meaning non-moving; and “pressure,” meaning physical force. This pressure gets its strength from the weight of water. Water weighs, on average, just over eight pounds per gallon and a cubic foot contains around 7.5 gallons. That means a single cubic foot of water can exert over 60 pounds of pressure. When you multiply this over and over again, you can start to see why hydrostatic pressure is so intense.
Hydrostatic pressure is the number one cause for basement water issues. This is because before a home is built a large hole is dug to accommodate the basement. The footings are poured and after they cure, the walls are formed and then the floor. Then the areas around the basement are backfilled and this dirt is much looser than the virgin soil so when it rains, it fills up with water much like a swimming pool. Like a pool, the water at the deepest part pushes the hardest, and this excess pressure will work its way through the porous concrete foundation, into the basement space.
We highly recommend Cellulose Insulation. It is treated with a non-toxic borate solution that gives this material a Class-1 fire safety rating, the highest rating available. It also means that this will be both mold and pest resistant. Cellulose also offers a superior R-value compared to traditional fiberglass insulation. Cellulose is more durable, and won't compress, ensuring its effectiveness over time. Cellulose is also considered a "green" product. It is primarily made from recycled newspaper. The eco-friendly nature of the material combined with its energy efficiency makes it a great choice for homeowners who are concerned about the environment.
At a minimum there should be a 6 mil thick plastic vapor barrier. However these need to be changed out every few years due to rips tears, and they are susceptible to being chewed on by critters. We highly recommend a 20 Mil thick vapor barrier; CleanSpace. This is made of a woven material and is backed by our twenty-five year warranty against rips and tears.
It really depends upon what you are using it for, but in our business of insulating and keeping crawlspaces clean, it's not a good choice even though it's an industry go-to.
Fiberglass insulation is only effective as long as it's flush against the surface of the space it's intended to insulate and that's the problem with a crawlspace. The moisture in a crawlspace causes the insulation to get heavy with moisture and then the insulation pulls away from the floor above. Now, cold air can creep in between the insulation and the floor, rendering it useless. Additionally, rodents just love the stuff and will make homes out of it and they will urinate in it, and since 50% of the air in your home rises up from your crawlspace... well, you get the picture. Consider Cleanspace Encapsulation to get the insulation quality you deserve and save money on your utilities.
Ideally, waterproofing should be installed on all new construction to retroactively keep homes dry and healthy. Homes naturally settle and can have water creep into the space over the years. However, this doesn't always happen. To protect a home, we do recommend waterproofing on all homes to prepare them for the inevitable water damage. If water is already present, we offer a free inspection and estimate to remedy the problem.
Ideally a sump pump should be installed in the lowest point of your crawlspace or basement. This will allow the water to naturally grade down to this point so it will not pool. When a large amount of water is present or the area is generally level, we do then recommend a drainage system is installed to assist directing the water to the sump pump. From here the sump pump will divert and push all of the water safely out and away from the home's foundation.
There are a multitude of materials that can be used for waterproofing. However, to have a long term solution, we have systems set up for both crawlspaces and basements.
Crawlspace: We offer our full crawlspace encapsulation. This uses a perforated pipe system in a silt sock to collect groundwater and grade it down to a sump pump. From the pump water is pushed out and away from the foundation. We then insulate the space with TerraBlock along the dirt floor and spray foam along the foundation walls. This is all then entirely sealed with our 20 Mil woven vapor barrier; CleanSpace. This goes under each wooden post, anchored along the walls, and sealed into place. As a final piece we add in new vent covers and a SaniDry dehumidifier.
Basement: We use the WaterGuard drainage system. This is laid in a trench around the home's interior parameter on a bed of gravel. The walls will be covered with either BrightWall or ThermalDry radiant barrier which collects moisture from the walls and directs it down to the drain system. The drain system is then cemented over to create a smooth finish to the flooring. The drain system moves the water to a sump pump and then out and away from the home. We then add in a SaniDry dehumidifier to keep the space dry and healthy.
If your crawlspace has a 6 Mil vapor barrier installed, then it should be changed out every few years. If your home experiences a large amount of water intrusion, then this will cause the 6 Mil barrier to be moved out of place. Once it is askew, water can begin to leak onto the vapor barrier, carrying mud and debris. Once water is stuck on top; mold and mildew can easily occur which can cause long-term damage to your home. If you find dirt or mud on top of your 6 Mil vapor barrier, give us a call, we can help.
