Well since I saw Greenmosters thread about his wall that eveything that could have gone wrong did, it reminded me of a job we did last season. I really don't post much on here, and since it's not freaking snowing figured I would. First job is just a small patio we did for a good maintenance customer that wanted to use a particular patio block. St00pid me said ok to it. The absolute cheapest cr@p I have ever seen in my life! But he was stuck on it, and boy did it cost him. After we picked up this wonder 18"x18" block and got it to the property, we noticed that about almost 1/2 of each pallet was either broken, or defected. So we sorted through them, and sent the guy back with the unusable pieces. Of course they don't have enough to replace it and have to get it for the next day. Next morning go get the block. By the time the driver got back to the yard... guess what?? More were broken. Long story short, base had to be absolute 100% perfect cause there was just no tamping these things once they were down. Will NEVER touch one of these block again... never.
