Groundwater & Basement Water Intrusion in Raleigh, NC
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
This creek is barely a stream and it does a great deal of damage.
It is receiving the runoff of ground that was forest and farm when the channel took its shape, and it has almost no room in its section to absorb a rise. So the level jumps rather than spreading, and falls back just as fast. Nothing upstream holds any of it. For a property beside one, whatever is going to be done has to have been arranged in advance.
The subdivision opposite drains nothing like this one.
Because it went in during a different decade under different rules. Growth here has come in waves and each carried the stormwater requirements of its time, so a 1980s neighborhood and a 2015 one have unrelated systems and unrelated expectations about what an owner maintains. Which era a property belongs to explains a great deal about how it behaves.
Water reaches the wall from the uphill side rather than from below.
Rock weathered to a soft layer holds water and moves it down the slope along the boundary with sound stone beneath, so a basement cut into that ground meets the flow at its uphill wall under pressure. A drain along that footing, taken out to daylight where the fall allows, is the arrangement that works, and on a sloping lot it frequently needs no pump at all.
