And that brings up another thought - One of Techo's big sales pitches is that their products are pumped up on Viagra, meaning they boast about the density of their products. And I have never bought into this. When we started out, we installed Belgard pavers. And ya know.....I have to say we have never had a problem with Belgard's paver's density, not even back when they were having major quality issues. Never. So yeah, I understand the importance of a decent density of pavers, but it's not something that has ever been an issue in the last 12.5 years.
