Trap Rock Gabion
Upon meeting the clients at a Minneapolis coffee shop I was invited over to look at an old timber wall that needed replacing. The solution was to build a steel gabion wall constructed with 1/4 inch steel mesh and 2″ x 2″ angle iron. Gabon filled with 2 1/2″-12″ trap rock. The project continued later in the season with the removal of a wood stoop, deck and stairs. Various finishes of bluestone were used to build a new stoop, patio and stairs. Client now has better access to their backyard and more entertainment space.
Challenge
Existing timber wall revealed a concrete walk and wall that had to be removed. There were also site parameters that required exact measurements of gabions. Wood deck and stoop had to dismantled section by section. Old concrete stairs were discovered under wooden stoop and had to be removed.
Solution
Once the timber wall and hidden concrete was removed footings were installed and 3/4″ clear rock was leveled for the gabion to rest on.
Three separate 6-8 foot long gabions were set and bolted to footing and to each other. Trap rock filled the gabions. Bluestone landing at base of steps was installed next to gabion.
Once the deck and hidden concrete steps were removed, all by hand due to limited access, bluestone stoop, patio and stairs were installed.
