Serving Harbison Canyon
Groundwater & Basement Water Intrusion in Harbison Canyon, CA
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 hillside burned last summer. What changes for this winter?
Almost everything about how that slope handles rain. Burned ground sheds instead of absorbing and carries soil, ash and rock along with the water, so a storm that would have passed unremarked can produce a flow of material rather than a flow of water. The raised risk lasts several years while vegetation returns, not a single season.
There is one way out of this canyon.
Which is the fact that should shape any plan here, because the event that threatens a house is the same event that closes the road. That argues for deciding on the forecast rather than on what is visible outside, and for going early rather than assessing. Once the creek is across the road the decision has been made for everyone still in the canyon.
The creek is a footpath nine months of the year.
And a watercourse for the rest, which is easy to forget in September. The catchment above is short and steep and the ground sheds rather than absorbs, so it fills within the hour. Whatever was stored, planted or built in the channel through the dry season is what moves in February. Treating it as a creek year-round is the safer habit by some margin.
