Groundwater & Basement Water Intrusion in Takoma Park, 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 creek rose and dropped before anyone could react.
Urban streams do exactly that. The catchment above is largely roof and pavement, so rain reaches the channel within minutes instead of soaking in over hours, and the level spikes and falls inside a single storm. Nothing upstream is holding water back. For a property near the channel that means the plan has to be already in place, because the warning time is measured in minutes.
The basement is a separate unit. What does that change?
The exposure and the insurance both. A below-grade unit holds the lowest openings in the building and receives whatever the drainage cannot take, and the contents in it belong to someone who may have no cover at all. It is worth being explicit with a tenant about what is covered and what is not, and about what should not be kept on the floor, before a season rather than after an event.
Roots keep getting into the line to the street.
Old clay pipe under a mature canopy is close to guaranteed to have them, because the roots follow the moisture leaking from the joints and then open them further. Cutting them restores flow for a season or two; lining or replacing the run is what removes the cause. A camera survey shows how much of the pipe is affected, which is what decides between the two.
