History of the CB Group begins in 1995, when brothers Jerzy i Lesław Górscy decided to start a joint business related to the construction industry. Establishing a DIY store called Centrum Budowlane (CB) was one of the first local initiatives on such a large scale after the communist era.

The dynamics of the company and the consistent implementation of our strategy of development has let us to create high-quality trading program, based on several distribution channels. Our products are available through specialized distribution companies, wholesalers, constructors’ warehouses and the DIY-store channels.

We supply manufacturers of construction chemicals, roofing systems and insulating materials in complementary products offered by them (the so-called: “Private labels”). We also support industry roofing, insulation systems, “dry construction” and tiling.
