Groundwater & Basement Water Intrusion in Annandale, VA
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
There is no creek near us and water came up in the street.
There may well be one underneath it. A good deal of drainage in older suburbs inside the Beltway was piped decades ago, and the watercourse still carries the same flow with no surface expression at all. When that pipe is exceeded, water surfaces at low points and behaves exactly like a stream, because it is one. Historic mapping often shows a creek where a road now runs.
It was over within the hour. Is that normal?
It is normal for a channelized urban watershed. Straightening and piping removes the storage and friction that used to spread a flood over hours, so the rise is fast, the peak is high and the recession is quick. The consequence is that there is no useful warning window, which means protection has to be permanent and structural rather than something deployed when the rain starts.
Which part of the house is the water most likely coming through?
Most often a window well or an areaway, not the foundation. Both have a drain at the bottom that silts and leaves over within a season or two, and once it is blocked the well is simply a container that fills and empties through the window beside it. Clearing those drains before the summer storms is among the cheapest and most effective things available on housing of this type.
