Ventilation System
A sump pump is important to drain unwanted water from underground, just as important as a sump pump, another important underground installation is an air ventilation system. Without fresh clean air, nobody would comfortably survive underground, hence Wayne installed two 12-inch vents, both in front and in the back vicinity of the container. This is a clear indication that Wayne had planned to spend quality time underground. And for what practical reason maybe?
Pouring Concrete To Coat the Bunker
It seems like the perfect plan is coming together and everything looks in place, yet Wayne can never be too cautious. With freezing winters and the possibility of ground shaking movements, Wayne decided to shell his bunker with concrete all around, including the top surface of the bunker. Pouring concrete can be a tricky task, but Wayne seems to have done it perfectly well.
Evenly smooth and fitting to the rest of the yard, even though it is taken up by the project at this point. In the end, we will be looking at a backyard masterpiece.
