Groundwater & Basement Water Intrusion in Alexandria, 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
The waterfront streets flood on clear days now.
Relative water levels here have been rising, so tides that once reached only the lowest ground now reach further, and it happens without any storm. It is a trend rather than an unusual year. The practical implication is that a property's own history understates its future exposure, and decisions about mechanical equipment and ground-floor use should be made on where the water is heading.
Our building is two hundred years old. Does the usual drying advice apply?
Much of it does not, and applying it can cause harm. Old plaster, lime mortar, and original joinery tolerate dampness but are damaged by rapid drying and by modern sealants. Replacement in kind is often impossible. A contractor experienced with historic fabric will dry more slowly over a longer schedule and know what can be saved. Ask about that experience before work begins rather than after.
We are inland and have never seen the river. What applies to us?
The stream rather than the tide. Inland neighborhoods drain into a channelized watercourse that rises and falls within a couple of hours of a heavy cell, giving no useful warning. That is a completely different problem from the waterfront's, and remedies do not transfer. Knowing which of the two your address is exposed to is the first useful thing to establish.
