Basement Waterproofing in Strasburg, PA

Strasburg stone has been losing its mortar since the 1700s

The cellars along Main Street were laid up in lime mortar before the Revolution. Drainage on its own does not hold a wall that is still shedding joints.

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 Strasburg

Limestone valley floor

The oldest cellars in Strasburg Borough predate the country. Field stone laid in lime mortar, walls that are as much rubble fill as they are masonry, and two and a half centuries of water working through the joints one winter at a time. Homeowners here often mention a floor that always has grit on it. That grit is the wall coming apart in slow motion.

Underneath is limestone, which delivers storm water quickly through open channels in the rock. A stone foundation gives that water a hundred places to come through at once, so it rarely presents as a single leak. It presents as the whole base of the wall going dark after a rain and staying dark for a day and a half.

On a Strasburg property we repoint before we drain. Pointing gives the wall its structure back and closes the easiest paths; the interior drain at the footing then handles the water that is still going to arrive every spring. Installing a system against a wall that is actively coming apart only delays the same conversation by a few years, so we quote both together or we say why one will do.

What we install in Strasburg

Interior French drain tied into a sealed sump basin with a battery backup, because the volume shows up fast and all at once. Wall vapor barrier where the block has been wicking.

  • White mineral crust (efflorescence) on block walls

Questions from around Strasburg

Straight answers

The mortar in my Main Street cellar crumbles when I touch it. Is the wall unsafe?

Usually the wall is sound and simply out of mortar, which is a repointing job. Field stone that's been standing since the 1700s is generally still doing its job as long as the stones haven't shifted. Our estimator will tell you plainly if he sees movement, and you get the photos.

Do you repoint and waterproof in one job, or is that two contractors?

One job, one crew, one warranty. On a Strasburg stone cellar we point the wall first so it can hold, then set the interior drain at the footing. Splitting them across two trades is how the second one ends up working against the first.

The whole bottom of my wall goes dark after rain and stays dark. Is that normal for a stone foundation?

It's normal and it's still worth fixing. A stone wall gives water a hundred small paths, so it darkens across its whole base, and a single clean leak is rare. That moisture is what keeps pulling the lime out of the joints, which is the part that eventually matters.

Can you work on a house this old without damaging anything historic?

The work is inside at the footing, and the pointing is done to match what's there. Nothing about the exterior, the facade or the streetscape changes. We've done plenty of Strasburg Borough cellars and can show you finished work nearby.

How dry can a 1700s Strasburg cellar realistically get?

Dry enough to store things in and to stop the wall deteriorating, which is the honest goal. Once the pointing is done and the drainage is relieving the pressure, these cellars hold up well. We'd tell you before quoting if yours has a condition that limits that.
