Our mission is to provide advanced construction products and innovative technologies that meet the specific needs of the residential, industrial, and underground construction sectors in Bulgaria and the region.
Strategic Infrastructure & Pioneering Spirit
Over the years, "Leaf Group" has established itself as a key partner, technological consultant, and supplier in the mining industry, tunneling, and infrastructure construction. A testament to our leadership position in the construction and structural rehabilitation of strategic projects is our collaboration side-by-side with global consortia such as Penta Ocean - Mitsubishi JV, TAISEI Co., Alpine Bau GmbH, and others.
Pioneers on the Bulgarian Market:
We are the first company in Bulgaria to introduce and deliver specialized robotic shotcrete application systems (MEYCO Potenza).
