Our history

During the eighties, arose a strong demand for restoration and conservation of public properties, monuments and town centers in Italy and in Europe which created a demand of adapted machines and tools. Then, the Buonanno brothers, led by a strong familial tradition in mechanical manufacturing created BUNKER starting in the building and geotechnics sector producing cement injection pumps.

That experience was a success. Since then, BUNKER provided an important contribution to the evolution of cement-based materials pumping and spraying systems aiming at the constant innovation of products and giving the largest attention to the demands of end-users.

Those are BUNKER's commercial policy guidelines, we are a young company that quickly obtained an important role in the sector thanks to the honesty, competence and professionality of its staff.
