Groundwater & Basement Water Intrusion in Roanoke, 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
It rained moderately in town and the river came up hard.
The mountains either side receive considerably more from the same system than the floor does, because the terrain lifts the air and wrings it out. So the river responds to rainfall nobody in town experienced. Following what fell on the slopes rather than what fell in the yard is what makes these events predictable instead of surprising.
The creek off the mountain rose and fell within an afternoon.
Short steep ground does precisely that. Everything above reaches the channel at once because there is nowhere for any of it to be held, and the section is too small to let the water spread, so the level jumps and then drops back within the afternoon. Channels that size are not gauged by anyone, so what somebody photographs at the time is the only record that will ever exist.
Slope or valley floor: does it change the work?
Completely. On the slopes water arrives sideways through the ground and meets the uphill wall of a cellar under pressure, and the work is interception above the building. On the floor it comes from beneath as the river raises the level in the soil, and the work is a pit and a pump. Advice for one is close to useless for the other.
