When my wife worked in a restaurant over the mountain from us, she would bring 5 gallon pickle buckets home, they worked great for hauling sand and gravel up to the cistern site to put in a storage bin for supply for mixing concrete in a wheelbarrow, it took a lot of trips due to the weight of the sand and gravel, there was just no way we could haul a full bucket but we got it done, thanks to 5 gallon buckets. I've used those same buckets to keep left over cement from turning into a solid piece, in the past I have lost many 94 pound sacks of cement even when stored in what I believed to be a good dry place.
