bewildered: All the ancient buildings in Timbuktu are made of clay and have withstand pressure for more than two hundred years. Continue with the lies. |

1) Take great care not to allow laterite to fall into the blocks. 2) Use damp proof membrane. 3) Fill in the blocks holes with wet concrete if budget allows. Good luck on your project. 2 Likes |

BluntCrazeMan: Five (5) pages and no straight answer to your question. You know why? You can't learn Engineering on the pages of a social forum. For starters, there is no relationship between absence of "chaining beam" and filling of pore spaces in hollow blocks. To your question. Straight answer is there is nothing wrong in filling the voids in hollow block wall with any sort of materials your imagination an suggest. If there was, construction methodology textbooks would have prescribed that brick layers ensured that nothing drops within the hollows while laying. Go back and pick up your books on "Strength of Materials" for clearer understanding on why Engineers use one type of material instead of the other. Like why wood instead of Steel? Now there is a difference between Partition block wall and a load bearing block wall. Truth is that 99.9% of the design and building construction you see today in accordance to BS8110 doesn't utilize load bearing walls. So the block wall in the foundation you referred to are just Partition walls. Whether you use hollow blocks or Solid blocks it makes no structural difference. So its not considered in the design. Use of hollow blocks was just to save costs. But it's so easy to bore a hole through for thieves to penetrate. That answers your question as to the origin of filling with broken blocks and pouring in weak concrete. Shalom 1 Like |

It is not advisable, in time to come once the soil absorb water the soil will start to grow later it turns to semi stone which will start breaking the blocks |

Is advisable to fill with weak concrete, if cracks occur in your foundation,solid filled can prevents the building from cracks. |

Good day , it's a wrong practice laterite is not weak congret , so instead of giving strength to the foundation walls it will weaken it expecially when the water level of the ground increase , it will soak the wall and the laterite will rise , it can cos cracks . |
Re: Is It A Bad Practice To Fill The Holes In Foundation Block-Works With Laterite? by Zif82: 3:36pm On Sep 04, 2021 |
The reason why the hole is filled with weak concrete is to prevent dampness and secondly strenghten the wall against earth movement but not with laterite |

I'm not a civil engineer but I am a student of quantity suroand I've been fortunate enough to be in a building environment for about 10 years, from labour to chain man to assistant surveyor even as a student of quantity surveying, the best practice is to fill the blocks with concrete, nor as strong as the one used for beam, but if in a case where you'll like to use laterite, use red sand to avoid vegetation growing later. But if you can afford it concrete is best |

BluntCrazeMan: It's actually bad to fill the hollow of the blocks with laterite. It's better you fill it with broken block or weak concrete; 1:4:8. The laterite absorbs and retains moisture which affects the strength of the block as time goes on. |

saferoom: Wow! Honestly, I appreciated this. Would you believe I’m undertaking my Industrial Training currently as a Civil Engineer, and everything you explained out here was what we did on the project on site. We used weak concrete, like 1:9:18 and whatever. But your write ups here actually go a long way on shedding more light. I doff my hat |

AvalonSpace: There is a great wrong in this. You are giving these block high moisture content as the block will now be faced with external moisture content from surrounding soil and internal capillary rise in moisture as a result of the laterite used in filling the blocks. This is a high risk for the block and its strength. |

If you know u will be able to compact insde the blocks to avoid settlement of the sand and without damage to foundation walls...then u are good to go. |

Re: Is It A Bad Practice To Fill The Holes In Foundation Block-Works With Laterite? by Zaxinorepub: 9:42pm On Sep 04, 2021 |
Earth pressure acting on the hollow sandcrete block is the reason for filling the block with mass concrete.... filling it with laterite is actually wrong as it adds load and not strength to the block...... |

Filling the hollow blocks of your foundation with laterite is wrong. We fill it with concrete to control termites, don't be surprised that termites will destroy the room trusses soon after you complete your building construction. |
Re: Is It A Bad Practice To Fill The Holes In Foundation Block-Works With Laterite? by jpride(m): 7:30am On Sep 05, 2021 |
Since the building does not have beam (chaining) that'll will help in load distribution and stability, it will be advisable u leave the holes open and partially cover with concrete. Pls don't ever introduce laterite. It's never an acceptable building material |

Just thinking, Than using hollow blocks and later filling it, is it not best to use solid block for the foundation? |

Hatesin:I still don't get it, maybe because of cost. I've seen some use 5" and 6" hollow blocks then later starts filling it, like why not use the solid blocks that doesn't require filling. 1 Like |
