Good environmental product - Boardwalk decking with no in ground footings

Part our our research for Domus included boardwalks between pods. A new product by Rocla called permatrak offers a cost and ease of installation solution to installing decking when access to skilled workers is problematic. They can be considered as an environmental product as low impact during construction and in ground footings are unneccesary. Supposedly minimal physical impact protects ecologically sensitive sites. Hmmn... i wonder. Could be a lot of hype. Sorry no image. Wouldn't upload.
