About Us


VRD Limestone was established through the initiative power of its owner Vivencio Rey Diano in early 2016 and has finally materialized in 2021. It started its venture on a small scale by offering the products in the market then eventually offered them to big market players. These days, the VRD Limestone Industry has potentially established its hold in the market and has already owned types of machinery that aid in Lime mass production.


Since the establishment of VRD Limestone Industry with its plant located in Km.93, Purok 2, Brgy. Magsaysay, Nabunturan, Davao De Oro, the company has already expanded its operation not only in the nearby cities and municipalities but has also reached some provinces and cities located in Visayas and Luzon.
