thursday the 20th's step by step break down part 5
16. Aside from pleasing the Gods, the strongback (that's the big vertical thing in the middle of the photo) provides a place for the walers to sit. What are walers you ask? They are the horizontal boards that get pressed against the form ply to keep them from bluging out from the pressure of the rammed earth. The strongback also adds support--and does so right in the middle of the wall, where it nees it most. By fastening the strongbacks at the same distance from one another at the top and the bottom, the notion is that the wall will obey and maintain the desired dimension.
17. Here Grant puts on the first horizontal waler.
18. Meanwhile on the otherside of the wall, the other strongback is set up. Ready rod is secured into the footing
19. The strongback is set up--it is secured at the top and the bottom. Now the front is ready to recieve the walers.
20. One waler
21. Three wailers
