Do you have cracks in your foundation walls? One of the top causes of basement leaks in homes with poured concrete foundations is leaking cracks in the foundation walls. When owning a basement with a poured concrete foundation, it is typical to find cracks. The repair for a leaking crack in a poured concrete foundation wall is a polyurethane crack injection. We use a low-pressure crack injection to complete the repair. The repair process begins with setting ports in the fracture approximately every 8-10″. The fracture is flushed out and cleaned, and then the polyurethane is injected into the crack to complete the repair. The polyurethane pushes its way through the 9-inch-thick poured concrete foundation to form a watertight seal.

Foundation Crack Injection

Any cracks or openings in the foundation wall can allow water to find its way into your basement. This commonly occurs where the main water service line or sewer line passes through the foundation wall. If you have rainwater entering your basement through either of these penetrations in the foundation wall, we can help. The repair for this is very similar to a polyurethane crack injection. We perform a low-pressure injection to complete the repair. Injecting the leaking area in the foundation wall without drilling into the foundation wall is a benefit. The repair process begins with setting ports around the pipe; once the site is prepped and the surface sealed, the area is flushed out and cleaned. We then inject the polyurethane into the area to complete the repair. The polyurethane pushes its way through the 9-inch-thick poured concrete foundation to form a watertight seal.


Suppose you are experiencing water intrusion along the bottom of your foundation wall where the wall and slab meet. In that case, the most effective solution is to install an interior sub-floor drainage system.  The goal is to keep water from entering your basement. In some cases, the original foundation drain system has started to fail, most commonly due to the accumulation of silt, causing it to clog. When your original sub-floor drainage system fails, it allows hydrostatic pressure to build upon the foundation wall. During heavy rains, the water pushes into your basement through cracks in the floor or where the foundation wall and slab meet. If your original system fails, it will not only capture water beneath your floor but also releases water inside a cinderblock foundation wall. This water intrusion can happen well before it builds up high enough to enter the home. Our internal systems use state-of-the-art drainage below the floor to direct the water into a sump basin with a dual pump system. The pump systems incorporate a secondary pump with a battery backup to ensure you stay dry even in a power outage.

Basement Waterproofing Systems

Suppose you have a brick veneer outside your house, and you see water enter at the end of the foundation wall. In that case, water is most likely getting behind the brick and entering the area known as the finger space, which is a small gap between your foundation wall and the brick. The water typically enters that small space in a different location further up the wall and travels down the area until it finds its way into your basement. Many other companies will try to sell an internal system. We have a solution we can do from the outside your home; which is a much more affordable and less invasive process.

Finger Space Drain

Radon is a naturally occurring gas that leads to over 20,000 lung cancer deaths per year in the United States. Radon is a colorless, odorless, and tasteless radioactive carcinogen that most commonly enters the home up through the foundation and becomes trapped inside. All foundation types are susceptible to radon transmission from the soil, including homes with a basement, crawl space, and even slab on grade homes. Once radon enters the house, the stack effect pushes the gas upwards through the home, leaving anyone inside at risk of exposure. The taller the home, the more efficient the stack effect is at pushing the gas up, much like a chimney; the taller the structure, the more draw there is. The EPA states that extended exposure to radon, especially at levels over 4.0 pCi/L, significantly increases health risks. Testing the radon levels in your home is recommended once every 2-5 years to ensure a healthy environment is maintained. Statistically, 1 in every 15 homes is estimated to have a high radon level that needs to have a properly designed and installed radon mitigation system. Call Schmitt Waterproofing today to schedule a test and make sure your levels are safe.

If we detect radon in your home, Schmitt Waterproofing will professionally design and install a radon-reduction system that can bring radon levels back down to a safe number. Many variables in homes can affect a proper radon mitigation system design as each home is unique. Schmitt Waterproofing offers custom-tailored radon reduction systems for each home to ensure that any high radon levels are reduced. Give us a call today to schedule an estimate if you have radon in your home, or call us to schedule a test if you are unsure of the radon levels in your home.

A poorly draining property is at risk of water damage every time it rains. Poor drainage contributes to cracked and settling driveways and foundations, pooling water in yards and around swimming pools, erosion issues around the home, insect problems. It is the leading cause of dead landscaping. The best solution for poor drainage is a properly designed, professionally installed drainage system. Drainage systems can consist of various items to help protect the home and property. We come up with a custom plan that works for your needs. We use multiple methods to control the water around homes, including dry creek beds, French drain systems, and catch basins. We will implement the necessary design for a drainage system to make your drainage problems go away depending on your issues.

French Drains are one of the most known and commonly utilized drainage solutions. Unfortunately, many contractors and homeowners misuse and improperly install French Drains, causing them not to be as effective as possible. Many homeowners experience overly saturated areas in their yards that never seem to dry out. French Drains are a great solution to address soft, soggy areas in the yard, preventing your family from enjoying it. French Drains can be a great way to address drainage issues without leaving an open trench or drainage ditch. We use perforated pipe in combination with a porous fabric and drainage rock. As the gravel-filled channel begins to fill with water, the water will enter the pipe and flow away.


When dealing with a large volume of surface flowing water that is causing erosion, dry creek beds are by far the most effective way to channel this water and protect your land from further erosion. We use a silt fabric and large river rock to create dry creek beds. Creek beds can be a great landscape feature if appropriately built.


The gutter systems installed on most homes today are a substantial contributing source of water around the house and throughout the yard. Many homes with yard drainage issues can significantly benefit from properly extending the gutter downspouts away from the home. When downspouts dump next to the house without being correctly routed away, the dirt becomes saturated, and several things happen. Water begins to pool in areas, and hydrostatic pressure begins to push on the home’s foundation. Over time this can lead to drainage and erosion issues, foundation settlement, and basement leaks. A properly installed drainage system is essential to protect your home.

Underground downspout extensions are a commonly overlooked item on homes and can contribute to water-related damage to the house. Keeping the gutter system cleaned and maintained, with extensions in place, is a top priority to protect your home from water damage. Over time, water can reach areas it shouldn’t. Rainwater can damage soffit and fascia boards, causing landscape erosion, basement flooding, and even structural damage. If these problems are not solved, water also can get under your roofline and damage your entire roof. In this case, your best option is to hire a professional.

Retaining walls are used for various purposes, including preventing erosion on hillsides, aesthetic goals, and leveling and stabilizing yards. Without a properly designed retaining wall, additional drainage issues and possibly even a wall failure is possible. Many contractors don’t account for the amount of water, and soggy soil held on the backside of a wall and sometimes neglect to install a retaining wall drainage system. At Schmitt Waterproofing, we are not only retaining wall experts but drainage experts as well. We have the expertise to properly design and build the right retaining wall for your needs. We are happy to offer a variety of materials, including concrete block walls and wooden timber walls.


Crawl spaces, in general, are relatively unhealthy as they are breeding grounds for mice, snakes, and other pests with high humidity levels and outgassing dirt. Approximately 60% of the air you breathe inside your home is circulating up through your crawl space. Once a crawl space has been encapsulated and the exterior vents have been sealed off, musty smells and high humidity levels that lead to mold and mildew can be controlled, and the breathing health inside the home will be significantly improved. If your crawl space is flooding, a perimeter drainage system with a sump pump must be installed to ensure all groundwater is adequately addressed. This system is a critical element to ensure that the foundation is protected and the crawl space remains healthy. Many crawl space issues get ignored as many homeowners do not enter the crawl space often.


As a homeowner, it is essential to watch for signs of foundation failure. The sooner repairs are made, the better. One of the first signs of foundation movement can be cracking sheetrock in walls or ceilings inside the home. Horizontal or stair-step cracks in block walls and diagonal cracks in poured walls are some of the most alarming signs of structural movement in a foundation wall. Carbon Fiber Foundation Reinforcement is proven to have a higher strength than its steel beam predecessor. Carbon fiber straps are low profile and can be painted. We offer carbon fiber foundation reinforcement that addresses any inward movement in foundation walls less than 2 inches. We use Carbon Fiber Reinforcement Straps and staples to secure foundation walls and prevent any further deflection of the walls.
