Arlington Heights IL is a sprawling Chicago suburb to the northwest of the city with a population of more than 75,000. It contends with nearby Palatine and Schaumburg for the title of the largest village in the United States.
The village is known in horse racing circles as the home of a large thoroughbred track, Arlington Park.
For more than 31,000 homeowners, however, Arlington Heights is where they hang their hats, raise their families and take care of their houses. Given that two-thirds of the homes in Arlington Heights are at least 35 years old, it should come as no surprise that homeowners there wrestle with the same repair and maintenance problems that plague owners of older homes everywhere, including problems with water in their basements.
Most homes in Arlington Heights have basements and frequently experience seepage problems. Even though there are different reasons for seepage, many of the problems can be corrected or prevented by installing drain tile.
Many homeowners are confused by the term “drain tile” because it calls to mind something that is used on floors or bathroom walls. Back when subsurface drains were first used, they were made of clay roofing tiles but modern-day drain tile is constructed of plastic pipe.
Drain tile can be installed inside or outside the foundation and functions the same way in either case. Perforated pipe is laid next to the foundation footings in a surrounding bed of washed gravel and connected to a sump basin. Underground water pressure is relieved by the pipe and the water that enters the pipe is carried to a sump pump for removal from the house.
Whether to install interior or exterior drain tile is determined by the source of water in the basement. If water is seeping into the basement through cracks in the floor or through the cove joint between wall and floor, interior drain tile is recommended. If seepage is coming through the wall because of deteriorated mortar joints or porous masonry units or concrete, then exterior drain tile is needed.
Installing interior drain tile begins with removing a strip of concrete around the perimeter of the basement floor and digging down to the bottom of the footings. Washed gravel is added to a depth of several inches and then flexible, corrugated, perforated pipe, wrapped in a sock of filtration fabric is laid on top. The pipe is connected at both ends to the sump pump, more washed gravel is added and the cement floor is replaced.
When the water table rises and creates hydrostatic pressure under the foundation, water that would ordinarily enter the basement through the cove joint or cracks in the floor goes into the pipe instead and is carried off to the sump pump for discharge.
Exterior drain tile is often installed when an exterior waterproofing membrane is being applied to seal the wall against water penetration but can also be done as a stand-alone project. Washed gravel is poured into the bottom of the excavation that has been dug for the membrane to be installed and perforated, rigid PVC pipe, which stands up well against soil exposure and exterior pressures, is laid in and connected to a sump basin. More washed gravel goes on top and the excavation is backfilled.
Ground water pressure is alleviated by the exterior drain tile pipe and the water is carried to a sump pump instead of being forced through or over the foundation wall.
