Flood Damage >> How To Build In The Flood Plain

A damp basement can be a nightmare, especially after mildew creates its eye-watering, nose-offending stench. There are two enemies to overcome: damp air condensing on interior walls and ground water penetrating the exterior. One can address condensation by drying or How To Build In The Flood Plain heating the air in a basement to raise it above the dew point.

The simple way to do both is with dehumidifiers. However, they are expensive to operate. In this article, the author presents and How To Build In The Flood Plain explains a construction solution to the wet basement problem.Water can enter your basement in one of three ways.

Through cracks in the basement wall Through the joint between the basement wall and the basement floor Through the basement window wellCheck the exteriorgradingto ensure that surface water flows away from your house. With the passage of time, How To Build In The Flood Plain soil often settles around the foundation wall. Water ponds in these settled areas, and what doesn't evaporate may find its way into your basement.

Flower beds and other plantings may hold water against the wall. When regrading, avoid placing soil next to wood or siding. Examine the window wells, How To Build In The Flood Plain and ensure that all contacts between the outer foundation wall and the window well casing are well sealed.

First correct the surface drainage to force surface water away from the wall, and then check for the presence or How To Build In The Flood Plain absence of footing drains.

If you don't have construction drawings of the wall footings, try to get them from the builder or your local jurisdiction's Building Inspector files. Check for the presence or How To Build In The Flood Plain absence of an exterior drain by looking for a plastic pipe discharging at a point in your yard below the level of the footing or, if a storm sewer inlet or manhole is nearby, looking inside it to see if there is a plastic pipe through its wall from the direction of your house.

If the drain is there, but there is no flow and your basement continues to leak, the pipe may have become plugged with earth or How To Build In The Flood Plain tree roots over time. Correcting this can be a major job. It may require snaking-type equipment to reopen plugged drains along all or part of the length of the footing.
