Frequently asked questions
The sewer is separate, not combined. Why does May still wet the basement?
Because the path is the masonry and the openings, not a surcharged main. These houses were built with areaways and coal chutes at grade, and a 4.9 inch May fills those openings. Limestone joints under the lot add a second path at the footing. A separate sewer keeps sewage out of the floor drain. It does nothing for a chute that is sitting in a puddle. Cover the openings and trace the limestone; do not assume a modern main solved 1949.
The sidewalk is higher than it used to be and water sits at the areaway. Is that the city's fault?
It is the grade. Decades of sidewalk and alley raising have flattened or reversed the fall the mason set, so roof water that used to leave now stops at the areaway. Whether the raise was public or private, the water does not care. Restoring fall to the alley or adding a drain at the areaway puts May rain back on a path that exists. The brick is not newly porous; the lot is newly flat.
A rubble wall weeps after May even when the chute is closed. Where is that moisture coming from?
The stone itself. Rubble laid without a damp course takes perched water from limestone joints, and a closed chute only stops the splash path. May rain that entered the rock still shows as a wet line along the footing. Exterior drainage at that wall, and keeping roof water off the uphill side, is the remaining work. The chute was one inlet. The rubble is the other.
