Paul,
Yep, it was the antifreeze type of stuff. This house was build in the early to mid 50's and was groundbreaking for this time.
As well it was so nice to wake up and put your feet on a warm floor, still remember it today.
Not sure how it would work on sand and pavers but well worth a search on the internet, then sending some emails out to people who have built this type of system before.
