The propane torch trims back the polystyrene foam cleanly and neatly for installation of rebar, electrical conduit, and plumbing installations.
Footing and Panels.
Removing foam with propane torch. By removing the foam, the 3-d panel can easily slide down over the re-bar. The concrete or shotcrete then fills this void space, thus acting as your tie down.
Installing pre-cut 3-d panels as a header over openings.
When installing the 3-d panel roof panels, the panel is lifted over the wire mesh angles and fastened in place from the under side. Another wire mesh angle is fastened to the top side of the 3-d panel.
Shoring is required on the underside of the ceilings. I recommend spacing the shoring every four feet under the roof panels.
Installing flat mesh and cutting window openings, the opening can be cut with bolt cutters or a skill saw.
Applying cement, the cement is mixed four parts sand, one part Portland cement, applied with hawk and trowel.
As shown, plan ahead and pre cut your 3-d panels. A skill saw with a diamond edge concrete cutting blade works best. And be sure to where ear plugs and protective eye wear.
Installing the two-foot by four-foot corner angles onto the 3-d panels. The angle will support the roof panel, it is being fastened with the pneumatic fastening tool.
Bond beams are created when a re-bar is installed over large openings to reinforce the concrete walls. This can be done by removing the foam core and installing re-bar.
Wiring can be placed behind the wire mesh and should be incased in flex tubing or conduit.
Installing red clay pipes for roof drains and covering windows with visqueen before applying shotcrete or cement mortar mix.
The hopper or panel sprayer can be dipped into the wheel barrel like a shovel to pick up the cement.
