Groundwater & Basement Water Intrusion in Groveton, 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. Where did the water come from?
Very possibly from a stream that is still there but underground. A great deal of drainage in older suburbs inside the Beltway was piped or culverted decades ago, and the watercourse continues to carry the same flow with no surface expression. When the capacity of that pipe is exceeded, water surfaces at low points and manholes and behaves exactly like a stream, because it is one. Historic maps often show a creek where a street now runs.
The flooding was over in under an hour. Is that typical?
It is typical of a channelized urban watershed. Straightening and piping a stream removes the storage and the 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 period. Preparation has to be structural and permanent rather than a response taken when the rain starts.
Does the fall line actually affect our drainage?
It affects what the soil does, which changes over surprisingly short distances here. Piedmont material sheds water and delivers it to the surface system; Coastal Plain material takes it in and raises a water table. Two neighborhoods a mile apart can therefore need entirely different remedies for what looks like the same problem. Advice that worked elsewhere in the county is not automatically applicable to a specific lot.
