While installing the french the trailer was filled with 2 tons of gravel. Suddenly the trailer would move anymore.

WTF? I thought I hit a sink hole

Apparently it turned out to be an improperly abandoned septic tank from ?? 1950s maybe.

I asked a buddy what to do, and he said break the cover in and fill it with sand.

It is great to have a friend with a tilting bed. In a few hours it was filled and now I’ll let it set for a month to compact the soil then I’ll plant some grass on it.

Another problem corrected at the house.
