6/27/2012 – I need to buy Large = 26?"L x 16"W x 17?"H, but I was wondering if I have to dig vertical - how many of these boxes can put on top of each other, let's say that my hole is 15feet, can I use as many boxes to cover the 15feet or do I have to dig horizontal.
Thanks
I hope that you will reply please.

Response From TJB-INC: You can go as deep as you want. The Blox are load carrying. We have put parking lots on top of them.
