Live from within the newly completed Cooling Porch retaining walls, it’s the Thermal Mass & Buoyancy Ventilation Research project team! We’ll take you through the evolution of both north and south wall and all the earthwork in between. If you stay tuned ’till the end you’ll see Cory’s latest artistic venture; a short film titled, “Le Grevier.”
North Wall: Complete!
After laying and leveling the dry-stacked concrete highway barriers, the team backfilled gravel and earth against the wall. Directly behind the walls are drains that are wrapped in landscape fabric and covered with gravel. This protects the drains from getting clogged with Hale County Clay. Behind the gravel, the team piled and compacted earth. They are reusing the dirt excavated for the building foundations. This process repeats for each course, refilling the initial dig. The Cooling Porch is still a hole in the ground, but it’s becoming a far more precise hole in the ground.
Voila! The joints, pattern, color, and textures of the north wall turned out fantastic. The team was astonished by the uniformity of the wall and the blending of the different blocks despite using reclaimed materials. On to the south wall!
South Wall: Complete!
The process of constructing the south wall was essentially the same as the north wall. Small concrete footings were poured wherever the retaining wall went off the building foundations. The team also completed the installation of the drainage. The space began to form right in front of their eyes!
The team feels the space looks exactly as they drew it–which is both slightly surprising and super satisfying. All the measuring, drafting, and double-checking produced a beautiful pit. And, bonus, the reuse of materials is a surefire way to build with the environment in mind and luckily these concrete highway barriers turned out to be the perfect durable, stackable material. The backfill and dug-out stairs makes getting around site a whole lot easier. It’s all coming together!
Thanks for following the progress of the soon-to-be chilly demonstration space! Stay tuned for SIPs construction and laying the ground surface in the Cooling Porch. Now, for your enjoyment, follow the life of a scoop of gravel in Cory’s feature film, “Le Grevier.”
Le Grevier: Directed by Cory Subasic starring Wheelbarrow, Shovel, Bobcat, and Gravel with a special appearance by Livia Barrett as “Gravel Girl.”
