Dehumidifier

An appliance that removes moisture from the air. Determining the proper unit for a particular space is best left to the professionals.

Differential Settlement

The result of the underlying soils moving, or sinking unevenly. This settlement causes cracking to the foundation since one side of the structure is sinking faster than the other.

Discharge Line

A discharge line is how a sump pump moves water out of and away from the home. Consider the size of the discharge line and ensure it is large enough to capture all the water needed to be removed. Also, pay attention to where the water is being pumped to. Make sure it is far enough away from the foundation and the area is graded away from the home.

Downspout Extension

Downspout or gutter extensions attach to the end of the downspout and help move water out and away from the home.

Downspouts

Ensuring your gutters are clean flowing is important to your homes water management system. Downspouts are a pipe that carries rainwater from the gutters to a drain or out and away from your home’s foundation. Downspouts should be placed far enough away from your home’s foundation to prevent water from running back to the foundation.

Drain Tile

A system of pipes laid against the foundation of the basement. Small holes collect water and remove it from the home, usually with the assistance of a sump pump, before it can enter the home and cause damage.

Drainage Pipe

An exterior drainage pipe collects groundwater and directs it away from the home’s foundation before it can cause damage. The pipe is usually buried along your home’s perimeter at the base of the footing. They can be prone to clogging since they are buried in dirt.

Dry Well

A hole in the ground filled with gravel to help with drainage. Typically a sump pump liner, or pit, is placed inside the dry well. A drywell allows water to accumulate prior to kicking on the sump pump motor, extending the life of your sump pump.

Drywall

Drywall is used to as a finishing material for interior walls. Commonly made of pressed fiberboard or paper, this organic material absorbs water easily and mold growth is common.
