Groundwater & Basement Water Intrusion in Fullerton, 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 basin near the house is dry and has been for years. Is it a risk?
It is not a risk in the ordinary sense; it is the reason there has not been one. These structures are dry most of the time by design and fill only when the flow exceeds what their outlet can pass, which happens rarely. An empty basin is the normal state. What is worth knowing is who maintains it and whether the outlet has been checked recently.
One end of the house has cracked and the other has not.
On a graded hillside pad the two ends stand on different material: cut ground at the back, which is original and firm, and placed fill at the front, which settles when it takes on water. That shows up as diagonal cracking and doors sticking at one end. The water consequence is that drains and slabs crack at joints as it moves, so a repeated failure in one run usually has movement behind it.
Nothing has rained since March. What is worth checking?
The roof, and in autumn rather than after the first storm has already found the faults. Two thirds of a year without rain is ample for a seal to go, a flashing to lift or a gutter to silt up unnoticed, and then a single afternoon discovers all of them together. Thirty minutes up there in October outperforms almost any drainage spending here.
