Case Study: Stone Wall Rebuild
Before and After
The Assignment:
Take the leaning wall down, rebuild the footing.
Build the wall with stronger support, remove the lean.
The Underlying Problem:
This 100 year old wall's footings had failed, causing the wall to lean.
Vines had also helped create damage, digging into the mortar.
Due to the lean, and further damage up the hill, many joints had failed.
Being on a hill, the slope and street vibrations contributed to failure.
Poorly Built
Over the years, repairs had been made, but not nicely.
Demolition
Removing the cap and stones carefully.
The wall went nearly 3 feet below grade.
Sorting the stones was important: some above grade, others below.
Building with Mortar
The base is 3 feet below grade.
Rebar and concrete form the base.
Layer by layer, with more rebar.
