The history of Glenview, IL has a lot to do with planned communities. In fact, the village got its start as a planned community called The Park, established by a religious group from the New Church (Swedenborgian) whose members were among the first European settlers. Many years later, at the end of the 20th Century, Glenview enjoyed a significant growth spurt when it developed The Glen, a more modern community on the site of the shuttered Glenview Naval Air Station.
Today, Glenview is home to 45,000 residents who live in nearly 16,000 homes and enjoy the suburban lifestyle with its excellent schools, established neighborhoods and wide variety of houses. Like most Chicago suburbs, Glenview experienced a postwar building boom in the 50’s and 60’s and, as a result, half of the village’s houses were built before 1970. These older homes help create the ambience of Glenview but can cause maintenance headaches for their owners, many of whom are experiencing wet basements.
Of course, like any home repair, the approach to wet basement waterproofing is determined on a case-by-case basis but there are three common methods often used in Glenview homes.
Interior Drain Tile – One of the most versatile approaches to wet basement waterproofing is to install interior drain tile. Installed below the basement floor at the depth of the foundation footings, interior drain tile relieves hydrostatic pressure under the foundation that would cause seepage through the cove joint and cracks in the concrete floor. Consisting of perforated plastic pipe embedded in washed gravel, a full interior drain tile system has both ends terminating at a sump basin where a sump pump will eject the water from the house. Interior drain tile requires no maintenance once installed.
Crack Repair – Poured concrete foundations are common throughout the Chicago are and they are found under most homes in Glenview. A likely cause of a wet basement in such a foundation is a non-structural crack caused by settling or lateral pressure from wet soil. The best way to repair such a crack is from the interior, injecting it with expanding polyurethane. The polyurethane fills and seals the crack all the way to the outside soil, creating a permanent repair that remains flexible when it cures to prevent minor foundation movement from re-opening the crack.
If the basement is finished or the crack is otherwise inaccessible from the inside, it can be permanently repaired from the exterior by digging a small hole down to the foundation footings at the site of the crack and filling it with sodium bentonite clay. The clay forms a pliable, impermeable barrier against water seeping in through the crack.
Exterior Waterproofing – Ground water in the soil surrounding a foundation can seep through porous concrete or masonry or over the top of the foundation wall. This can be prevented by applying a waterproofing membrane to the outside of the foundation. The membrane, asphalt-modified polyurethane, is troweled onto the wall in a thick coat and cures to form a permanent barrier against water. This should not be confused with “damp-proofing,” a thin coating that is usually sprayed on during construction.
If the ground water problem is severe, exterior drain tile can be added and a heavy-duty drainage board installed over the membrane to protect it and channel water to the drain tile.
