Foundation Repair in Christiana, PA

Christiana houses stand half on rock and half on fill

On a hillside lot the uphill end of the foundation was cut into shallow bedrock and the downhill end was built up on soil. The two ends have been moving differently ever since.

Foundation in Christiana

Southern schist uplands

When the older houses in Christiana went up on the slopes along the railroad, the builders dealt with the grade the usual way. The uphill end of the cellar was dug down to rock, which around here is never far below the surface. The downhill end was built up, with the footing set on whatever soil or fill was there. The house was level on the day it was finished, but the two ends have never rested on the same kind of ground.

Rock does not move and soil does. Over a century and more, the downhill end settles a little further than the uphill end, and the brick or stone above records it: a stair-step crack running down toward the low corner, windows on that side out of square, a porch pulling away from the front wall. Meanwhile the uphill wall carries water that rides the top of the Piedmont rock toward it, which is slowly washing the lime mortar out of the stone joints on that side.

Each end of the house gets its own repair. Helical piers go in under the settling downhill corner, screwed down to firm bearing and set to hold it, with a lift attempted only where the old masonry can take it. The uphill stone wall is repointed with a lime-compatible mortar so it keeps flexing the way it was built to. Your written plan lists both parts separately, and the estimate is free.

What we install in Christiana

Drainage on the uphill side first — interior drain plus exterior interception where the grade allows — and a discharge line routed far enough downslope that it does not simply return.

Questions from around Christiana

Straight answers

Why is only one corner of our Christiana house sinking?

On a hillside lot, the uphill end of the cellar was usually dug into rock and the downhill end built up on soil. Rock doesn't settle, soil does. After a century or more that difference shows up at the low corner.

There's a stair-step crack in our brick running toward the downhill corner. Is that connected?

Almost certainly. The brick is recording the settlement below it, and the crack points toward the part of the foundation that has dropped. We'll check the footing at that corner and measure how far it's moved.

Are helical piers safe to use under an old stone foundation?

Yes, when they're installed carefully. They're screwed into the ground with little vibration, which suits older masonry. Under a Christiana stone wall we're cautious about lifting, and we'll often stop at holding the corner where it is to protect the stone above.

The mortar on our uphill cellar wall is soft and sandy. What's happening to it?

Water riding along the bedrock hits that wall and slowly dissolves the lime mortar out of the joints. Repointing with a lime-compatible mortar puts the strength back without making the wall too stiff for the stone it's holding.

Our front porch in Christiana is pulling away from the house. Is that a foundation issue?

It can be either one. Porches often sit on shallower footings than the house and settle on their own schedule. We'll check whether the porch is moving by itself or whether the house corner behind it is dropping too, because the fix is different.
