Rexology: The wall section is not sufficient to take the self weight of the beam itself now u have ur roof load wall load and self weight of ur beam on the angle not more than 225mm max.. if the lintel had come out a little beam u could have lap it well there's always a satisfactory lap for this kind of thing it can kills when there's an uplift action from wind and u tie ur roof to this particular member at the terrace solution from my own view since the load is small u can introduce a dummy column to receive the stress ..safer this way since we can't estimate how solid ur strip is or block.. 3 Likes

nannymcphee: Maybe spiritually. But physically, once you remove top soil up to 200mm, it should get rid of loamy soil. Thereafter, dig your foundation. No cassava can stand in the way. 2 Likes |

Rexology: It is either your builder took his eyes off the ball (lack of attention to details) or possibly a cowboy builder. Take a careful look at the pictures I have attached including your original picture. In your picture (with the red arrow) you will notice that the cross beam is placed directly on the blocks without a column underneath the beam. At that point, I have arrowed in red, there should have been a column to bear the load. But without that column, the blocks are serving as load-bearing (with the generally poor quality of Nigerian blocks), and not making a good job of spreading the dead load of the beam and the roof. This is the cause of the crack. The best practice is for the cross beam to rest on the LINTEL. Take a look at my pictures (red highlighting). The all-round chaining of the lintel spread the dead load better and effectively. That is the structural purpose of all-round chaining. With your building, your builder failed to take advantage of the chain lintel by not placing the cross beam on the lintel instead he/she placed the beam directly on the blocks. This is asking for trouble in most cases. SOLUTION Introduce a column underneath the beam (the red arrow) - DIY approach or talk to a structural engineer if you don't feel confident. 5 Likes

ArcToyin: To avoid cement stains on the roofing sheets and ensure that the parapet is well dressed.i plastered after the carpentry work. My parapet doesn't need screeding as the mason did a good job

diordaves: I have couples of locations in my build, especially internal door areas where the beams rested on the blocks. I didn't see cracks on the wall. I have also seen it in other people's builds in my area. During the plastering stage of my house, those Togolese guys were consuming so much cement in plastering and when I asked them, they said some door beams areas didn't have column and they needed so much thick plaster on the entire walls, in and out, to avoid any visible cracks on the wall later. It is up to one year now that I did plastering of the house and haven't seen any visible cracks on the walls like the one shown here. 1 Like |

Focusmind: It could be any of the following: - You use 9in strong and solid block. - Your foundation is well compacted. - Your structural design is ![]() - Your build wasn’t rushed. Believe me it has nothing to do with the thickness of the plastering. 4 Likes |
Re: General Topic Thread-To Discuss Anything And Everything in Building Construction by Focusmind: 6:23am On Dec 18, 2020 |
n3xt: You are not far from the truth. The four listed points above are applicable. Nine inch were used. My foundation after sand filling the raft was left for more than 18months with rain hitting it, fully compacted and weeds even started growing there before we started the German floor. As a kobo kobo man, the build is not rushed. It has helped me also to rectify certain defects as the build progresses. That's one of the advantages of slow and steady work. Apart from the additional large windows mounted this year as we opened up more walls, we haven't done anything this year. Na that your DIY matter I still the reason ![]() 2 Likes |

Focusmind: The “fixed-mindset” and the “this-is-How-we-do-it” attitude of our artisans made me become a DIY enthusiast. The first step is always the hardest. I don’t handle every project by myself. I only equip myself with everything needed to carry out major DIY projects including the tools, materials and the skilled professionals. I show them the first step and ask them to replicate and perfect it. Guess what? They’re all enjoying it.

Focusmind: Your blocks are putting up a better job of spreading the load in your situation. It's not the plaster job. Plaster can only paper over the crack. Plaster work is just decoration, not structural. 2 Likes |

Rexology:It's clear the build has columns, but from the picture earlier you can see the point where the crack occurred has no support, in my lame man opinion the crack is due to the combination of mass and gravity vs resistance force (column)......I think your architect or builder has some questions to answer there. 1 Like |
