danowena: Ok sometimes we don't understand what the term raft foundation exactly means. The term raft is related to the term raft boat. google raft boat. A raft foundation just like a boat needs to be water tight , if not the boat will capsize because of the water that gets in causing it to be unstable or over weight, water is heavy (hence why blocks are not used because the cement/mortar used to bond the blocks together will fail over time and lead to water entering the boat/foundation) another important requirement is that a raft/boat also needs to be stable , imagine if you have 10 fat people in front of the boat and two skinny people at the back of the boat what happens? the boat tips if you are lucky to the front, but mostly likely will capsize. Now the importance of the gutter is this, The more soaked the soil is the less its weight carrying ability,so if the water from the roof hits the area exposed to this deluge of water, the part of the raft foundation close (underneath and by the side)to this water soaked soil is now perched on soil that has less weight carrying capabilities, so guess what happens ? the raft becomes unstable like the boat with the fat and skinny people on board mentioned earlier on. This area of the foundation starts sinking but not the whole slab, it then means that parts of the walls are being pulled meaning they will start cracking, serious fractures will occur in the wall system holding up the house, the house could then collapse/capsize like the boat. Although I am an experienced builder I am also a farmer, so please spread the word about Jessam Cattle Ranch and Farms. We have great pigs, chickens, eggs, ducks, goats, cattle etc Segcymoor is currently working in partnersghip on one of our (Dolphin Real Estate) residential building projects - https://www.nairaland.com/2753189/wing-duplex-flat-ajah-moore 4 Likes

So I found these pics on Segcymoor's thread. This are the kind of things we should be talking about or suggesting to QC1... not building basements in swamps o Who even want a basement in the swamp by the way? Abeg anyone heard of this waterproofing chemical before? can one use this for house plastering too so as to prevent wet walls ? 1 Like

Jessam: An unrelated flip example of keeping water away from foundation. In north Texas we actually have to water the edges of our foundation during the summer so that the soil doesn't pull away from the foundation. And we have to minimize the amount of water we allow to reach the foundation area in the rainy season = gutters. Yes, there's electronic device you can buy to tell you if you have too much or too little water. Technology. I yield the floor to my well heeled coforumers and their N4m foundations 1 Like |

OnetimeOnly: 26 meters! 0 - 2.5 m: Light reddish brown, silty sandy lateritic clay 2.5 - 19m: Dark grey very soft peaty organic clay with dead wood 19 - 22m: Light brownish grey soft to firm clay 22 - 24m: Light grey medium clayey silty sand (cmd)with occasional fine to coarse gravel 24 - 26 m: light grey soft to firm clay 26m - 30m: Light grey medium to density silty sand (cmd) with to coarse gravel Now the worrisome fact is that any geotechnical engineer who is not diligent may have stopped at 22 - 24 meter level of investigation and recommended pile points at that level. But note that this soil strata is good for only 2 meters and is closely followed by poor load bearing soil. I was made to understand that any house with pile points terminating at that 24 meter level is still at risk. Generally, the engineers recommend using steel casing for any pile going beyond the 20 meter mark. Hope this helps. 1 Like |

OnetimeOnly: I have modified my earlier post to capture the soil test report but...here it is anyway 0 - 2.5 m: Light reddish brown, silty sandy lateritic clay 2.5 - 19m: Dark grey very soft peaty organic clay with dead wood 19 - 22m: Light brownish grey soft to firm clay 22 - 24m: Light grey medium clayey silty sand (cmd)with occasional fine to coarse gravel 24 - 26 m: light grey soft to firm clay 26m - 30m: Light grey medium to density silty sand (cmd) with to coarse gravel Now the worrisome fact is that any geotechnical engineer who is not diligent may have stopped at 22 - 24 meter level of investigation and recommended pile points at that level.

Thank you for your explanation. I really enjoyed your analogy. Side note: I saw your posting on spyder880 thread of his estate. You mentioned your farm was very close to it. I missed out on his estate, though I'm still looking for land in enugu. I would really like to visit your farm when I'm around next just to see what it looks like and the kind of products you provide. Jessam: 2 Likes |

n3xt: I think we have talked about area boy strategy on this thread before. I spent grand total of n150,000.00 to settle them throughout the build. two deckings! There is usually disbelief when i tell people that but it all balls down to how you handle it. Use "reverse police delay" strategy. The area boys are always killing themselves in that axis as part of ongoing cult wars, but in my CDA we have effectively checked them and have no complaints for now. 1 Like |

Onuokwu:So apparently the soil test did not capture load bearing capacity at various depths? I think that test needs to be put in perspective. I know no 2 soils and building are the same, but for example burj all Arab foundation depth is 40m driven (don't crucify me for using burj, but we all know that building ) and it's in low loaf bearing soil so.... 26 m means your building foundations will be 8 stories deep for 3 story building 1 Like |

n3xt: @Brabus, @AbdulWastecx and @Spyderman I am looking at the attached Suspended Slab and two things crossed my mind. 1.) Those voids below the Suspended Slab are surrounded by four sides of vertical concrete Walls. This means each "cubicle" is an enclosed space. Since they are not sand-filled, it also means they would have water stored in them, below the suspended Slab. I am wondering, will it be a bad idea to introduce a small PIPE in one of the sides of the vertical walls so as to act as a channel for such water to flow-away, in situations where the really become much? It wont cost anything structurally but could help elongate the life of the structure or at least make underneath more "homely"! 2.) Those 1 x 12 Boards used to create the suspended slab will number no less than 300! At about a thousand each, that equates to about 300K! I am not sure but l am assuming those Boards will be permanently buried under the Slab. Since there is still a lot of need/use for those Boards as the building develops, l am wondering: Is there any way those Boards can be recovered (say for re-use). I am always looking for ways to "innovate and be more efficient" in everything l do, so you can understand the way l see things.... maybe a lil'different. whats your take? Lastpage! 1 Like

3strikes:I type not as an engineer but as a research manufacturer with some experience in cement setting application for wall screeding application. The product above would work to prevent wet walls. It has several ways of achieving this. These type of materials are organic polymer in emulsion form ( nylon or rubber dispersed in water). They reduce water requirement of a concrete or plaster slurry to give a denser concrete, they form light film over the concrete or plaster to trap water within the plaster/concrete to reduce evaporation and ensure proper hydration of the cement, the polymers form a waterproof nylon like materials over and within the concrete/ plaster filling the pores. In my experience as regards it's use in cement based screeding, further regular wetting for 48 hours after initial setting gives a very dense and waterproof surface. It improves the bonding of plaster to wall surfaces also and reduces tendency of plaster to crack because it gives it some level of flexibility. I understand checks online would give the benefits but list disadvantage based on their climate about failure of such plasters due to freeze thaw process that involves repeated freezing and thawing cycle of snow over the surface but I still have ones applied in areas in constant contact with water over 2 years that is still good. I can't say with certainty or know it's effects on concrete structural integrity but it has benefits in plasters. Any water based binder would do. Especially acrylics. 3 Likes |
