Foundation in Columbia

Susquehanna river terraces

The brick rows in Columbia were built close together and they were built early, and what they stand on is stone laid by hand into sand and gravel the river left behind. That is a perfectly serviceable foundation, and it has two weaknesses: the mortar between the stones, and the fact that sand moves when water runs through it.

Both weaknesses are worked on by the same thing. A spring water table rising into the terrace washes at the bedding around a footing and takes the lime out of the joints above it. The wall loses its bond, the footing loses a little support, and in an attached row that movement transmits sideways into the party walls of the houses on either side.

The repair treats the stone and the bearing separately. Repointing restores the bond so the wall acts as one mass again; piers replace bearing where sand has washed out from under a section. Sub-slab drainage keeps the water table from carrying on with the process. In a Columbia row all of that happens in a tight footprint with the dust contained.

What we install in Columbia

Sub-slab drainage with a high-capacity sealed sump and battery backup, mortar repointing on stone walls, and encapsulation where the space is unfinished.

Questions from around Columbia

Straight answers

The neighbours' house moved and now ours has a crack. Are those connected?

In an attached Columbia row, very likely. The party wall ties the two structures together, so movement at one address puts stress on the next. We can stabilise your section independently, and we'll tell you honestly if the cause is clearly next door.

How do you pier a house with no side access?

From inside the basement. Helicals are designed for exactly this and they're the reason the attached Columbia rows are workable at all. The estimator confirms headroom and access down the stairs before anything gets quoted.

Is sand a bad thing to have under a foundation?

Sand carries load well, which is the good half of what Columbia has. Its weakness is that running water moves it, and under the Columbia terrace a rising spring table does exactly that. Good bearing that can be washed away is a different problem from soft ground.

Can repointing alone stop a stone wall moving?

Frequently, yes, when the bearing under it is still sound. Restoring the bond makes the wall act as one mass again, and that's often all a leaning course needed. Where the footing itself has dropped, repointing alone leaves the cause in place.

Do all the houses in the row need doing at once?

No, and coordinating a whole row is rarely realistic anyway. We work on your property and design the repair so it stands on its own. If a neighbour's movement is driving yours we'll document it, which is useful if you decide to raise it with them.
