Basement Waterproofing in Christiana, PA

Christiana cellars leak on the side facing up the hill

The borough grew up along the railroad on sloping ground over shallow rock. On a narrow hillside lot the water arrives from the neighbor above, and it keeps coming for days.

Waterproofing in Christiana

Southern schist uplands

Christiana is a small borough, and most of its older houses went up in the decades after the railroad came through, on lots that are narrow and rarely level. The cellars under them are stone or early masonry, dug to whatever depth the rock allowed, often with a concrete floor poured decades after the house was built. Almost every one of them sits partway into a slope.

That slope and the rock under it decide where the water enters. On this eastern edge of the county there is Piedmont bedrock only a few feet down, so rain soaks in, meets the rock, and turns to follow its surface downhill. It travels under the yard next door and arrives at the uphill wall of your cellar, often carrying enough iron to leave a rusty streak where it runs. Because it is coming from further up the hill, seepage in a Christiana cellar tends to start hours after the storm and carry on for two or three days.

On a narrow borough lot the uphill side usually borders a neighbor, so exterior interception is rarely an option and the work happens inside. We lay a drain at the footing along the high wall, repoint any stone joints that are actively passing water, and run the line to a sealed basin with a battery backup, discharging to the street side where the grade falls away. The written estimate is free and names every wall included.

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

Water in our Christiana cellar shows up the day after the storm. Why the delay?

It's coming from further up the hill. Rain soaks in, meets the rock a few feet down and travels along it underground, passing under the lots above you before it reaches your uphill wall. That trip takes hours, and it keeps feeding the wall for a couple of days.

There are orange streaks on our cellar wall. What are those?

Iron from the ground. Water that's been riding along the bedrock picks up iron and leaves it behind as rusty staining where it seeps through. It's a useful marker for us because it shows exactly where the water is getting in.

Our uphill neighbor's yard is where the water comes from. Do we need their permission?

Not for the way we'd normally fix it. On narrow Christiana lots we put the drain inside your cellar along the uphill wall, so nothing happens on their property. We'd only bring them into it if an exterior fix clearly made more sense.

Can you waterproof an old stone cellar with a thin concrete floor?

Yes. A lot of older borough houses had the floor poured long after the house was built, and it's often thin. We cut it along the wall to lay the drain and patch it back. Where the stone joints are wide open, we repoint those first so the wall stops passing water.

Is Christiana inside your service area?

It is. Christiana is on the eastern edge of Lancaster County, a little further east than Gap, and our crews work out that way regularly. The inspection and written estimate are free.
