Homeowner: Why do I have water coming in on the floor where the basement wall(s) and floor meet?


Waters Basement Services, Inc.: Water comes in on the basement floor where the basement wall(s) meet because your drain tile has become clogged and can no longer accept water. Usually, this will begin in the furthest corner from where your sump basin is installed.

Water leaking in the basement where the walls meet the floor.

There are many early homes built without any drain tile. In the 50’s and 60’s basement drain tile was made of clay. When sentiment and tree roots clog this type of tile it usually cannot be cleaned as it breaks very easily. Later, the use of black corrugated flex pipe was used. This type becomes plugged solid over time. When plugged, it is also hard to clean (or impossible to clean) as it punctures easily. Unfortunately, drain tile may have been installed improperly: not enough pitch to sump basin, or when the concrete floor was finished the concrete may have filled the drain tile. In these instances, the homeowner would need to have the drain tile replaced.

Homeowner: How would you fix it?


Waters Basement Services would replace the drain tile with a white perforated drain tile to collect the wall and floor water into the sump basin and then be pumped out of the basement. Clean outs would be installed in the drain tile to enable the drain tile to be cleaned. Drain tile should be cleaned at least once a year (or more often depending on your soil type). With the clean-outs the homeowner can clean their drain tile with a garden hose, or have us perform this service. Equally important is maintaining proper grading along the foundation, and the gutter downspout placement. You always want water to shed away from your home.

Drain tile is the most important ingredient in effective basement waterproofing. In order to operate properly, your drain tile needs to be free of debris that can build up over time. Basement floor drains work the same. They need to be free of debris and be able to flow out into the storm drain. When the storm drain becomes overwhelmed with storm water, this water will pour into your basement. You can have a back flow preventer installed or plug the floor drain, which prevents water from entering your basement when storm sewers become overwhelmed and cannot take water out.
