If the section of the chimney above roof is higher than 2m, it is suitable to do static reinforcement. This reinforcement can be done with reinforcement through corner holes of a ceramic breeze blocks. Concrete armature (diameter 8mm-10mm) is inserted into these holes and concrete filler is poured in. By this reinforcement are created four reinforced-concrete pillars that will markedly strengthen above roof level part of the chimney.
Technical parameters of the chimney are definitely not changed by this reinforcement – exhaust through main ventilation holes in insulation still remains the same!!!
