In the new house from the developer "Grani" tried to fix the shelf on the wall, as a result, the nests under the dumbel were rolled out 5 times, all the dumbels were tested up to the chemical and the shelf still collapsed. Diagnosis: Wall material, silicate poor brick, consists of ordinary silicate dust without the addition of a binding substance. Conclusion: the technician of the manufacturer's enterprise took care of his safety in advance, when he comes to beaten on the roof with his same brick - it will be very soft and not painful. And another conclusion: I will call the developer a day ago, ask them to shoot the head of the supply department, because he clearly works for foreign intelligence and successfully conducts subversive activities.
