ventilation pipes installed

In a few days time we have made tremendous progress. The main structure has been completed and is ready for a roof pour.

Here, you can see the ventilation (in/out) pipes porting into the RECESS. The are 3" steel pipes, filtered, and easily capped from the inside. I use a hand-crank coal forge blower to provide the draw.

In this shot you can also see the initial waterproofing has been applied and the open sides have begun to be back-filled. The waterproofing is a combo of an exterior elastometric coating, and plastic sheeting.

The steel roofing, an industrial solution called Con-Deck has been attached, and reinforced this with a grid of re-bar. At this stage, the original pool is all but lost in its new incarnation.
