Testimonials

Recently used these on a deck I built and they far exceeded my expectations. They are super easy to work with and very stable. Much better than the old concrete type, in my opinion.

– Dennis D.

Wow, what a time saver these blocks turned out to be, rather than having to dig down. I was able to level the top soil and place these right on top! Where I live there are a lot of trees (Redwoods) with large and extensive root networks. Once again a life saver!!! Also these were much less expensive that the traditional foundation blocks.
