Crawl Space Waterproofing Repair
Tri-State Waterproofing has been providing crawl space repair for over twenty years. We inspect each home like it is our own. Our professional waterproofing inspectors start by checking the exterior of the home for disconnected downspouts, analyze the grade of the property and look for any signs of foundation settlement. We then inspect the inside for water in the crawl space and any efflorescence on the foundation walls. If your crawl space does show signs of water or moisture we will recommend installing a crawl space sump pump or gravity drain depending on the grade of the land. A crawl space dehumidifier may or may not be necessary. We will even check the floor system for dry rot, mold and mildew. If your floor system is in need of support we will locate those unsupported areas and provide the necessary solution. As you can see, there are many variables to account for. Our waterproofing experts will take the time to show you the problems and provide detailed explanations on what should take priority. Tri-State Waterproofing takes pride in being problem solvers NOT salesmen.

A dry crawl space helps keep your home healthy. All houses are designed to pull air from the crawl space up through the roof. In fact, 50% of the air that you breathe in your home comes from the area below your floor system. It is essential that you keep this area dry and at the appropriate humidity level. Many homeowners do not pay attention to this area of their home and create a health & financial problem for their family. Below are examples of extreme conditions due to long term neglect of their crawlspace.
Dry Rotted Floor System
Constant water vapor can cause your floor joists and framing to rot resulting in the need for a costly repair. The constant moisture will also soak into the insulation causing it to eventually fail.
Mold in Crawl Space
Standing water in your crawlspace enables the growth of mold and mildew. Whenever the relative humidity reaches above 55% mold spores begin to grow. Mold and mildew spores can get inside the house if left unchecked and might cause problems for your family.
Landscape Grading Above Vent
Landscape grading that is too close to a crawlspace vent can allow drainage directly into your home. We re-direct the water in a way that will not cause problems in the future.
Efflorescence in Crawl Space
Hydrostatic pressure pushes water through the block and overtime efflorescence stains the block white and black. Signs of Efflorescence are key indicators to where the water is coming from.
Crawlspace Interior Drain System
The Crawlspace Interior Drain system (CID) is installed inside the crawl space covering the entire perimeter. When water travels underneath the footing or through the wall our system collects all of the water and carries it to the sump pump. The sump pump then discharges the water away from the foundation, keeping your crawl space dry. After installing the drain we apply our vapor barrier on the floor. Our vapor barrier ranges from 9-36 millimeters. This system comes with a free transferable lifetime warranty guaranteeing your crawl space dry.
What’s the Difference?
Crawl Space Gravity Drain Vs Crawl Space Sump Pump Discharge
While inspecting a crawl space we look at the interior and exterior of the crawlspace to see where we can discharge the water. We would always prefer to do a gravity drain exit if possible and let mother nature (gravity) do its job. This is only possible if the slope of the yard allows us to. If a gravity drain exit is not possible we install a basin and sump pump into the crawl space to then discharge the water away from the foundation. Discharging the water in a correct location is essential to keep your home safe from foundation settlement.
Crawl Space Gravity Drain
- Requires a specific grade around the home
- No future maintenance needed
Our Extra Touch
If your crawl space requires a gravity drain we extend the perforated pipe underground and attach a critter guard to keep rodents and bugs from entering the pipe
- Guaranteed Dry Crawl Space
- Lifetime Warranty
Crawl Space Sump Pump Discharge
- Requires electrical outlet
- Sump Pump Battery Backup is needed for power outages
Our Extra Touch
If your crawl space requires a sump pump we bury the pumping underground and attach a bubbler pot to the end of the pvc. This ensures minimum erosion in the yard.
Crawlspace Power Post
Our foundation specialists install an adjustable power post that stabilizes the floor system. Our power posts are supported with a permanent footer and attached to a beam that spans the area of the sagging floor. This also helps prevent the floor from bouncing and creaking.
Power Post Vs Temporary Post
We often get calls from customers about sagging or sinking floors. This problem happens when the floor system is not properly supported or temporary supports are failing. Temporary posts are not ideal for floor system support. This often leads to other problems like sticking doors or windows. A crawl space power post is a permanent fix for these issues. They are made of steel to support the weight of the home. We install them with a permanent footing and proper placement on the crawl space ceiling to guarantee no movement.
Crawl Space Dehumidifier
Does your crawlspace or basement have a musky smell? This is because of your home’s humidity level. We can help you get rid of these problems by installing a commercial grade dehumidifier. The ideal crawl space humidity is 55% or below. This keeps mold from growing and turns mold dormant. Our crawl space specialist will help you choose the correct crawl space dehumidifier based on the cubic footage of the area.
Crawl Space Encapsulation
At Tri-State Waterproofing we do encapsulations a little different from our competitors. We have been working in crawl space for over twenty years now and we know what works. We start by installing an interior drain around the perimeter that will lower the water table and collect water below the dirt level. The water is then diverted to a discharge source either by gravity or a sump pump. We then apply a vapor barrier on the floor, walls, and columns. The vapor barrier stops six inches from the top of the wall. This allows a termite inspector to see everything they need to pass your home for inspection. We can also seal the crawl space vents and install a commercial grade dehumidifier. This process is a guaranteed fix for any home. Although this is not a true definition of an encapsulation this guarantees your crawlspace to be conditioned and looks identical to an encapsulation. If you have any questions about this process give us a call and we will get you in touch with a waterproofing specialist
It is imperative that you properly seal out moisture from your crawl space and Tri-State has the means to help; WARNING: Don’t try this at home. It is important that you have a professional inspect and treat your home for moisture and mold. Improper elimination of mold may result in mold contamination throughout your home further endangering your foundation structure and your health.
