This week I stopped off to check in with a landscape design client in Fredericksburg, Virginia. This is probably one of my favorite projects of the year. I’ll do a more comprehensive post (showing plan and elevation drawings, etc) in a couple of weeks when a few more details are completed, but I was too excited to wait.
The architect responsible for the addition figured out the orientation of a pool and the upper patio, and I ran with it from there. The homeowners were an absolute blast to work with, too.
The pergola is cedar, and was fabricated by The Cedar Store and assembled by the poolbuilder.
It makes for a pretty sweet outdoor space.
The plantings are still “too young for prime time” but it won’t take long till they look great. Give it a couple of years and this will be a swoon-worthy garden! Plantings were completed by Stadler Nurseries.
I walk by this wall whenever I walk to the post office in downtown Culpeper. Walls like this are pretty common in older neighborhoods like mine. Leaning and generally unhappy walls are, sadly, pretty common as well. So what gives? Why do these walls look like they’re ready to flop over on the sidewalk?
There are several possible explanations. The first is insufficient footer, or failure to tie the wall in with the footer. When building a masonry retaining wall in Virginia you generally want to dig down 24″ below grade, so you’re below the frost line. You then pour a beefy footer (thickness varies depending on application), often with rebar coming up from the footer to tie the wall to the footer. Our home was built in 1906 and renovated in the 1950s, and I can tell you with certainty that there was not a lot of digging to frost depth being done way back then.
Another possibility is insufficient drainage behind the wall. Water is a wall’s worst enemy. Hydrostatic pressure is a major cause of wall failure. The way we avoid a buildup of pressure is by using a “drainage chimney” of clean gravel behind the wall, along with periodic weep holes.
What makes this wall great for illustrative purposes is the fact that the wall likely started to fail because of hydrostatic pressure (water buildup behind the wall). This pushed the top of the wall forward, creating a gap between the wall and the slab. What’s right above the slab? Downspouts! So not only do we have a gap, we’re pouring gallons upon gallons of water behind the wall with every storm. Awesome.
So how would I fix this wall? I think we’re beyond the point of fixing something like this, and it needs to come out. Improper construction is hard to correct, and when it gets this bad – there’s no Band-Aid big enough.
