Anyone ever use Brock 36"L x 24"W Interlocking Paver Base Panel? (or Paverbase) http://www.brock-international.com/residential-pavers.php
It's supposed to be able to take the place of 4-5" of crushed stone. I have about 250 square feet and it would save me a ton of earth removal! It's about $13 through Lowes but it would save a ton of work. Thanks to anyone who has used it for feedback!
