One solid brick

They are used for masonry of load-bearing walls, partition walls and seismic washers.
Single bricks are also called single ceramic blocks. They are made of 100% natural materials. The brick units with a dense structure have 3 vertical openings formed by solid and durable walls. The single solid brick is preferred because of its high density, durability and at the same time its light weight - only 2.45 kg, which makes it lighter compared to the alternatives on the market.
