Foundation in Strasburg

Limestone valley floor

The cellar walls under the oldest Strasburg Borough houses are rubble-cored: two faces of field stone with smaller stone and lime packed between them. It is a sound system for as long as the mortar holds. Once the lime has washed out of the joints the two faces stop acting together, and the wall is carrying its load on friction and gravity.

That shows up as a bulge, a leaning course, or stones you can rock with one hand. Homeowners often mention grit on the cellar floor that comes back however often they sweep it. What they are sweeping up is the mortar, and how quickly it reappears is a fair measure of how fast the wall is losing its bond.

Repointing is the core of the repair, done with a mix suited to the wall so it stays flexible and does not tear the stone apart. Displaced courses get rebuilt. Where a span needs help we add steel, sized in the plan and recorded in writing. Then drainage at the footing removes the water that has been doing the washing out for two hundred and fifty years.

What we install in Strasburg

Questions from around Strasburg

Straight answers

Stones in the cellar wall move when I push them. Is the house safe?

It needs attention and it's rarely an emergency that night. A rubble wall that's lost its mortar holds on friction for a long time. That said, loose stones mean the bond has gone, so this is the point to book the inspection.

Does repointing an old Strasburg wall need a particular mortar?

Yes, and using the wrong one does real damage. A hard modern mix is stiffer than the stone around it and it tears the faces off as the wall moves. We point these with a lime-based mix that stays flexible, which is what the wall was built with.

Why is there always grit on the cellar floor no matter how often I sweep?

Because it's the mortar leaving the joints. The rate it reappears is a decent measure of how quickly the wall is losing its bond. It's the most useful symptom in an old Strasburg cellar and the one people most often dismiss as dust.

Can you rebuild one section without taking the whole wall down?

That's the normal approach. We take down and rebuild the courses that have actually displaced, shoring the load above while we work, then repoint across the full face so the whole wall acts together again. Whole-wall rebuilds are unusual.

Does a historic designation limit what you can do to a foundation here?

The work is below grade and inside, so the facade and streetscape are untouched, which is what most designations are concerned with. Where there is a specific restriction on your Strasburg property we'll work to it, and permitting is handled as part of the job.
