What We Do

We are a basement waterproofing company that proudly serves homeowners throughout St. Charles, Missouri. Our mission is to identify the root cause of basement water problems and provide dependable waterproofing solutions that help prevent leaks from returning. Homes in St. Charles often experience basement moisture issues due to clay rich soil, seasonal rainstorms, and groundwater conditions influenced by the nearby Missouri River.

Homeowners in neighborhoods such as Frenchtown, New Town, and areas near Frontier Park frequently report basement leaks following heavy rainfall. Because many homes in St. Charles are located on land that can retain moisture, water may collect around basement foundations when drainage systems are not properly directing runoff away from the home. As a result, groundwater pressure can increase along basement walls and eventually allow moisture to seep through porous concrete or small cracks.

In addition, homes located near the Missouri River floodplain or along lower elevation areas of the city may experience elevated groundwater levels during extended wet periods. When soil surrounding the foundation becomes saturated, hydrostatic pressure can force water through foundation walls or floor joints and into basement spaces.

Our team focuses on identifying where water is entering the basement and installing waterproofing systems designed to stop leaks permanently. By correcting drainage issues and protecting the foundation from moisture intrusion, we help homeowners restore dry and comfortable basement spaces.

We look forward to helping you with your basement waterproofing needs in St. Charles. Fill out the short form below to schedule your FREE, no obligation estimate today.

Common Problems

Keeping a basement from leaking in St. Charles can be challenging due to clay soil, groundwater pressure, and seasonal rainfall that saturates the ground around homes. When soil becomes saturated, hydrostatic pressure builds against basement walls and can push moisture through porous concrete or masonry materials. As a result, homeowners often notice water seeping through basement walls or entering along the joint where the basement wall meets the floor, especially after heavy rain.

Over time, shifting soil conditions can also cause small cracks to form in basement walls or floors. Even narrow cracks may allow water to enter the basement during storms. In many homes, these conditions lead to damp basement floors, elevated humidity, or musty odors that suggest moisture is slowly entering the space. Recognizing these warning signs early can help homeowners address basement waterproofing concerns before they develop into more significant structural or moisture related problems.

Water Intrusion

Heavy rainfall or melting snow can cause basement flooding which result in weakness in the ground beneath your foundation. Foundation sinking, bowing basement walls, and other structural damage can occur as the supporting ground softens. In the process, your’re left with an ideal environment for the growth of mold and mildew.

Biological Growth

Humidity in the soil and air releases destructive water vapor, debris, contaminates, and pollen. This damp air carries mold spores and musty odors, providing the perfect environment for insects and other pests, as well as wood rot. These issues affect your home’s structure and the quality of air in your living spaces.

Bowed Or Leaning Walls

All soil can expand and contract after a heavy rain or drought. When the soil supporting your foundation changes, it can cause your home to shift. During wet weather, water saturates surrounding soil, causing it to swell and push against subterranean walls. This lateral pressure can make basement walls bulge or leak, causing a wet and smelly basement.

How Do I Fix It?

Acculevel installs interior drainage and sump systems that redirect water before it can pressurize your basement. For many homes, our recommended solution is the Fast Track perimeter drainage system paired with a sump pump.

Redirection With Fast Track

The Water Tunnel is a channel system used to relieve hydrostatic pressure build up surrounding a structure’s foundation. Holes on both sides of the tunnel allow water to be collected from te footing/wall joints and under the floor. The unique bottomless design allows water to flow away from your basement at a flow rate 140 gallons per minute.

How Fast Track Is Installed

A narrow strip of concrete is cut along the perimeter to expose the top of the footing.
If the foundation is a block, small weep holes are drilled in the bottom course to relieve trapped water.
Pre-formed Fast Track sections are placed on/along the footing and connected to the sump basin; a wall liner or dimple board is integrated so moisture drains straight into the channel.
The trench is capped with new concrete flush to the floor, the sump lid is sealed, and the pump and discharge are tested.

Water Removal with Sump Pump

All Acculevel waterproofing systems drain into a top-of-the-line sump pump system and include safeguards against power outgages and pump failures. It is extremely important to have a second battery-operated pump in the sump liner in case of mechanical or power failure. Acculevel battery back ups are dependable and flexible.
