Here is our work in progress on the sunken grotto. Note how we took the bridge from reinforced steel, added 3″ of high tinsel strength concrete, and then ran our pavers right over the top. We have 4′ reinforced steel and concrete piers on all four corners of the bride as well. Don’t want it to move!!! In the end, we will finish out this landscape using many of our customers initial plantings as we saved them when it proved beneficial. I will take some pictures in a year and show you the project filled out with colorful plantings.
