Working north of the garage

I decided to focus on getting the waterproofing completed on the roof. However, to do this, I need to get the paraseal down. The paraseal, to be affective, needs to be put down just before being buried. It needs the pressure of the dirt to be preserved (in case it gets moisture soon after being applied; it needs the pressure). So we can't just put the paraseal up there, because it might rain and ruin it. Paraseal needs the pressure of the dirt.

So we can't finish the waterproofing until right before we're going to bury the roof.

So, I'm focusing on the north side of the garage, so that we can get the french drains down, waterproof the footings and the walls, insulate the walls, and then begin backfilling.
We figure that once we have that north end of the garage bermed, it'll be much easier to get onto the roof with dirt and we'll be able to put down the paraseal, the insulation and then put 3 feet of dirt on the roof.

So it's a cascading list of things to do, just to get what we want done, which is to complete the roof work.


To understand our plans for the roof, please refer to the following diagram.



The diagram shows the domed roof and the cold seams between modules. This is where the Paraseal and a liberal application of Ecoline-T go. We will spread Ecoline-R everywhere on the roof. Paraseal on the overhangs and up the sides of the parapets. We'll cover it all with 2 inches of insulation and then backfill.


The diagram generally shows the PAHS layer, which is a passive annual heat storage layer of insulation. They call it an "umbrella". The idea is that it will store heat or cool in the 2 feet of dirt between it and the roof. it will also keep that 2 feet of dirt dry, and it extends out over the berm, which will also cause any moisture to drain away before even getting deeper to the roof itself.

And then one foot of dirt goes above the PAHS layer. The PAHS layer is referred to as the "umbrella" in the diagram.
