Groundwater & Basement Water Intrusion in Glenn Dale, MD
Basement seepage, failed sumps, and hydrostatic pressure against the foundation are extracted and dried, and the path from the ground is identified so the loss does not repeat. Groundwater and basement seepage are extracted and dried only after the path from the soil is identified — a wall, a slab, a drain, or a failed sump. Drying the interior without stopping that path returns the same water to the same floor.
Frequently asked questions
The stream behind us is barely a trickle most of the year.
Headwater channels behave that way and it is not a guide to what they do in a storm. A small catchment that has been developing sheds water quickly, so the channel fills within the hour of a heavy cell and empties almost as fast. Size in dry weather tells you nothing useful. Watching it during a storm, once, is worth more than any amount of reasoning from how it looks in August.
Our neighbor's drainage fix did nothing here.
Where depth to rock varies over short distances that is common. One lot can sit on deeper soil where a drain intercepts a water table, and the next on shallow cover where water arrives along the rock from outside the property. Identical work gives different results for reasons invisible from the surface. A shallow test pit on your own ground in a wet spell settles which situation you are in.
Should we plan around the average year or the worst one?
The worst one, because that is the storm that causes the damage. Ordinary rainfall is comfortably within what the ground and the drainage handle; a tropical system delivering a month of rain in a day is in a different class and produces essentially all of the loss. Judging drainage against a typical year is the wrong test and it is the most common reason people are surprised.
