Building Lake Corona

I'll follow up to add I agree compaction on this particular job with the CTL will not be good. I'm dozing not carrying so less trips, no weight on bucket, and larger lifts.

Thanks for the updates jk. Many of us have followed you from the start.

Welcome. It may still be a failure in the end but thought I woukd take one more stab at fixing it.

Mr. JK, what are the details on your process?

Are you lifting, moving and dropping buckets of clay to where you need it, or are you pushing it from the source like a dozer to cover the areas needed?

Here's a quick clip from the go pro pushing some dirt.

I disagree. A tracked vehicle is designed to have a little weight as possible under it. The tracks spread the weight so the machine will not sink in and have more contact with the soil to increase traction.

The easiest way to prove this is to drive over an area of soil that has been spread with a tracked vehicle and see how far the tires sink. Even a pickup truck will sink in that soil.

Sadly, there are a lot of homes built by spreading the soil with a tracked skid steer that develop foundation problems over time. It might even be the number one reason for foundation problems in houses.

Even with a vibratory roller, or sheepsfoot roller, and the proper moisture, it is still very hard to get proper compaction to pass an inspection.

If you do even a half way job tracking it in and spreading in lifts a pickup isn’t sinking in. This track was made by a loaded dump truck and that dirt was packed using my described method. Would it pass a nuclear compaction test? Idk maybe not but I’m not building a skyscraper on top. The vast majority of pond and lake dams in the entire world were just tracked down with dozers. Vibratory rollers are pretty new to the construction industry. They had non vibration rollers but that wasn’t very common.

I worked for a civil engineering firm and did compaction testing over the years starting in 1984. Vibratory rollers new? I guess that’s a matter of perspective but they had them in 1984.

What percentage of dams in the country were built prior to 1984 or even 1960 vs after?

Removed most of the growth on the dam and spread a layer of clay on it today. I was able to track it in pretty well. I will say it's a hell of a ride if you back up too far and too fast at the top of the dam. I need to pick up a 45 degree elbow for the end of the inlet to get it off the pond basin. Looks like the rain missed us. Tomorrow I'm going to spread some clay on the side banks and hopefully pickup the vibratory roller on Tuesday. At the moment I'm about 20 hours in on the rehab including mucking it out. 78 gallons of fuel and burning about 4 gallons an hour according to the trip meter.

A few final pics before compacting. Picking up the roller tomorrow. My time this week is limited and rain moving in Friday and Saturday. I'm planning to compact tomorrow. If I can I would like to get bentonite down and mixed in at least on the lowest portion of the pond basin so if I do get some rain I don't have to completely drain it and wait for it to dry out again.

How are you mixing the Bentonite?

Trying to decide if I am going to till it in and recompact or do the blanket method where it is spread evenly then covered with another 4" of clay, then compacted. Blanket is supposed to be more effective but is obviously going to mean moving more clay and more time.
