emae009:Why is it necessary in storey buildings? Ground floors are the same whether bungalow or duplex, the standard for ground floors is the same. You make them damp proof and 150mm so they don't fail after a while. |

bodejohn: I found this disturbing! why? Oversite concrete not only good for damp proofing but also for preventing floor punching. That's why oversite concrete thickness defers based on the live load coming on top. It adds to the dead load on the house but does nothing directly to improve the strength of the building. It's not necessary to add oversite concrete weight to the structure, it can be separated. From my little research, the are many types of materials used in the dpc, we have only adopted the concrete slab here as the method used in most cases. This is where you mixed them together, Oversite concrete and DPC are different though oversite concrete can be used as a DPC material. The dpc majorly prevents upward movement of damp or moisture and seals the inside of the house from ants and some nasty rodents. A three or four inch thick of concrete slab should suffice. You're partially correct but about the thickness it depends on the load, imaging a floor for heavy duty machine or banking hall. The thickness and preparation must be different. 3 Likes |

DPC is different from an over site concrete. 1 Like 1 Share |

bodejohn: I thank you papi.....I have argued this over with some of my frds that are into construction,one even went to the extent of using lumps on the dpc before casting you can imagine the kind of waste he did there |

Emusan: I didn't mix this up, I am saying concrete or mortar can be used as DPC. And if this is what the OP was trying to do, he can achieve this with a 3 to inch thick slab. I didn't imagine the OP was planning to install heavy duty machinery in a two bedroom bungalow. |

ADAMUdaCOWBOY: what that means is that for a storey building casting of the ground floor is absolutely necessary but it's not for a bungalow since the load it transmit to the ground strata is not much... I didn't say you should reduce the thickness of the casting |
Re: Pls What Is The Minimum Height Of Oversite Concrete(german Floor)? by saydfact(m): 9:05am On May 31, 2017 |
Mup4life: Standard is 6 inches but since it's a bungalow and if it's a solid soil, then u can try 3 inches.. . But at least 4 inches if u can afford it.... If it's a waterlogged, swampy soil etc.. . Then follow ur engineers advice and design. Good luck 1 Like |

emae009: You talk like a road side taylor. Hw cud you advice that casting the floor is not necessary. OP, if you cant do 150mm cos of cost, dont go below 100mm i.e 4 Inches. There is every tendency that if you go below the above stated height, the floor might get broken or cracked easily wen something like say woods during roofing fall on it. I speak wit experience. |
Re: Pls What Is The Minimum Height Of Oversite Concrete(german Floor)? by emae009(m): 9:37am On May 31, 2017 |
RobbStark: Mr experience, before you start calling people names please read and understand their view first. first I stated that the minimum thickness is 150mm and that anything below that is a risk. then he said that the site environment is not prone to water so if it's a bungalow casting the ground floor is not as necessary as if it were to be a storey building.... that doesn't mean if you have the resources you shouldn't do it! I know we're all trying to learn, your experience is a good view |

avoid the risk contact an ARCHITECT CALL 08189728491 ::BETTER SAVE THAN SORRY. FLOOR SLAB-150MM, EVERYTHING INCLUDING DPC 450MM. AND IT ALSO DEPENDS ON WHERE YOU ARE BUILDING. |

bodejohn: Is it that without german floor a storey building cannot be ercected ? |
Re: Pls What Is The Minimum Height Of Oversite Concrete(german Floor)? by bodejohn(m): 11:23am On May 31, 2017 |
templeinyou: It can...but strongly not advisable or recommended... Remember that apart from the numerous benefits of a German floor to the building, you will require a strong and level ground support for the suspended floor. You don't want to have an undulating "decking" because a part of the ground floor sank due to the weight of the suspended floor. |

emae009:Floors don't serve the structural function of transmitting load to the ground. Loads in storey buildings are transmitted to the ground through beams and columns to the ground. Ground floors don't transmit load to the ground. 3 Likes |

6 inches is the approved standard. If u are keen to using 4 inches, let it be properly mixed with a good Portland cement. |
