Water seeps down through the soil on the left and gold arrows show it pressing against the wall. A green wall vapor barrier runs down the inside face of the block and turns into a sealed cove joint where the floor meets the wall, with a gold wedge marking the joint water would otherwise enter through. Below the floor slab, a green perforated drain pipe sits in a gravel bed at the footing and runs right into a sealed green-lidded sump basin, whose discharge line rises and carries water off to the right, away from the house.GradeWall vapor barrier over blockCove joint, sealedPerforated drain in a gravel bed at the footingDischarge, routed away from the house

Waterproofing in Columbia

Susquehanna river terraces

Columbia was a working river town before most of Lancaster County amounted to much, and the housing stock shows it. Long rows of brick built tight against each other, standing on stone footings laid by hand in the first half of the 1800s. Plenty of those cellars have never been dry and nobody currently living in the house has known them any other way.

The Susquehanna sets the water table under the borough, and through a wet spring it can sit above the level of a cellar floor. Water then arrives from underneath: through the slab where somebody poured one, and through packed earth and stone where nobody did. That is a different problem from a wall leak and it wants a different answer.

Sub-slab drainage is the core of the work. Collect the water below the floor, move it to a sealed basin with genuine capacity and a battery backup, and get it out of the building. Where a stone footing has lost its mortar we repoint before anything gets covered. In a Columbia row house that means working in a tight footprint with the dust contained, which is most of what our crews do all week.

Questions from around Columbia

Straight answers

Our cellar has been damp for a hundred years. Can it actually be fixed?

Yes, and Columbia cellars are a good part of what we do. The work is sub-slab drainage plus repointing where the stone footing has lost mortar. These spaces were never built to be dry, and they can be made dry, which are two different statements.

There is no slab, just dirt and stone. Where does a drain even go?

At the footing, same as anywhere, and then we pour an apron over the line so you end up with a working surface where the drain runs. Plenty of the oldest borough cellars keep a dirt floor through the middle and it doesn't affect how the system performs.

The houses are attached on both sides. Can you still work in there?

That's the normal case in Columbia. Crews break the work down to what fits through a narrow stair, run containment the whole time and clean at the end of each day. Nothing goes through your living space uncovered.

Does the Susquehanna have to flood for our cellar to take water?

No. The river sets the water table under Columbia without ever leaving its banks, and a steadily wet spring lifts it above cellar floor level. Most of the calls we take in the borough have nothing to do with a flood event.

The stone footing is losing mortar. Is that urgent?

It's worth handling before it's structural, which is the honest framing. Field stone standing since 1840 is usually still sound and simply out of mortar. Repointing while the stones haven't shifted is a modest job; waiting until they have is not.
