The Concrete Floor

The original plywood floor was laid on top of joist hangers. Since there was no base under the floor, other than the dirt ground, the joists rotted in less than 5 years. In 1988, it was time to replace the floor with better material. Learning our lesson, we decided that a concrete floor was the obvious choice, even at a higher cost than other alternatives.

The plan was to pay someone to haul several tons of sand to the top of the hill, dump it in the building (of, course, after we spent 1 month ripping out the old floor), then bring in the cement truck.

 

....jump to:

 

Rick Trembour lays Visqueen on top of the dirt floor. On top of that we'll throw the sand then pour the concrete later.

 

So, he calls in a front-end loader to lift his rear-end out of the culvert.

 

So, the next project is to haul the sand up the hill in Keith's trailer with his tractor- many loads of sand. That takes a couple of weeks. Keith shovels a load into the warm-up room.

 

Dan shovels a load into the observing room.

 

He just backed it up to the door and let the stuff slide.

 

Smoothing the cement out before it sets.

 

 

Andy Winzer sweeps the new floor.

 

The truck hauling sand to the hill. Oops. As he was crossing the land bridge over the culvert, he went over a bit too far to the right. His load shifted and he got stuck. He also broke the culvert pipe which we replaced 13 years later.

 

"I ain't going to drive my truck up that hill". So, he dumps his load in our parking lot - 500 feet from where we wanted it.

 

Keith shovels more as Dan watches.

 

 

A couple weeks later, we contract to have the cement truck make his delivery. After the sand truck debacle, we're worried about the cement truck, especially if he would make it up the steep hill. No problem.

 

 

 

 

 

The load being dumped into the observing room. Looks like we put reinforcing bar on top of the sand. Smart move.

 

We found that the floor was too low because it was difficult to observe with the scope pointed overhead. So, the following year, we installed a wood floor back on top of the concrete floor. Not rot this time, it's in great shape, over 10 years after installation.
