Interior French Drains
As with any waterproofing system of this type, this method leaves a gap between the floor and wall that allows water from the wall to flow down into the drain. This seepage could be from a window well, a wall crack, a pipe penetration or even just condensation. Basements that leak water at the wall to floor joint, through cracks or tie holes need to have the water diverted to the underslab drain tile system. The gap between the wall and floor that allows water to flow, tends to collect debris from the basement floor and clog, and the overall appearance is an unsightly addition to the home.
Many Kansas City homeowners deal with yard drainage issues. Yards tend to settle over time and natural erosion from rainwater can create drainage problems as well. Settlement depressions and flat areas in a yard will collect water, resulting in soggy areas or even standing water. French drains, defined below, are a proven and effective way to solve many yard drainage problems. Yard drainage can be related to your foundation issues, or they may cause future foundation problems if not addressed early. Arrow Foundation Repair professionals can assess the drainage issues from your basement wall and foundation to your downspout and throughout your yard – ensuring that you have a dry and well-drained property.
Exterior French Drains
A French drain is a trench covered with gravel or rock or containing a drain tile (perforated pipe) that redirects surface and groundwater away from wet areas. A French drain can have perforated hollow pipes along the bottom to quickly vent water that seeps down through the upper gravel or rock. French drains are primarily used to prevent ground and surface water from penetrating or damaging building foundations.
French drains are also used behind retaining walls to relieve ground water pressure. The concept for this type of yard drainage is simple. We dig out a trench from the wet area out to a section of the yard where the water can drain away from the property. The trench is filled with gravel and drain tile pipe, then covered with soil and sod. The wet area often will have a catch basin which is a small plastic box covered with a surface grill that captures excess water from the surface. The balance of the excess water is soaked up by the gravel and drain tile and is carried away to a downward sloping grade of your yard.
Rainwater drainage from rooftops is often ignored by home builders and homeowners. A heavy rainfall can produce thousands of gallons of water from an average roof. Most downspouts drain onto a splash block that is only a couple feet long – not nearly long enough in most cases to send water away from your home’s foundation walls. Downspout drainage may be one of the most cost-effective drainage solutions available. These drainage systems can collect most or all of your rooftop’s rainfall, sending it far from your home. For many Kansas City homeowners, downspout drains will drastically reduce the amount of water that collects around their basements’ wall and foundation.
We have clay soils here in Kansas City. Many yards have problems with lingering surface water. When new homes are constructed, home builders will grade the lots so that rainwater around the houses’ backyard flows through a swale down the side of your yard to the curb or storm drain. Sometimes, home builders don’t get their grades right and water becomes trapped. Other times, your yard will naturally settle in unpredictable places, blocking the drainage swales in some areas. When Arrow Foundation Repair assesses your drainage scenario, our goal is always to make sure that all water that collects under and to the sides of your basement will flow away from or be transported away from your foundation. Surface drainage is often the final pathway from your property to storm drains or natural runoff areas. Solutions include fixing the grade or creating an attractive rock drain way to carry larger volumes of water away from your yard.
