Look at the layering (the courses) in HCB fencing
The first thing is trench excavation obviously then you provide Masonry foundation which is strip foundation then you provide RC (reinforced concrete) grade then you extend columns from the grade beam you can’t have a column without a grade beam that’s why the fence is tilting .
የብሎኬት አጥር ሲታጠር የሚጠቀሙትን layer ተመልከቱ
መጀመሪያ trench excavation ዙሪያውን ይቆፈራል ከዛ በኋላ የ ግንብ(masonry) መሰረት ይሰራል በተጣለው መሰረት ላይ grade beam RC structure (ፌሮ ያለው አርማታ) ይሰራል column ሚቀጠለው ከ grade beam ነው አለበለዚያ አጥሩ (ብሎኬቱ) ይጣመማል/ያጋድላል
