The DB Group was founded in the early 1970s and was originally established to provide specialist sands to industry for cement testing and fuse manufacturing. In the early 1990s they brought PUDLO, a waterproofing product, into their range, and spent many years perfecting its formula and broadening the PUDLO range.
