I agree with you 101%.
Communication is Key.
I have worked with him before.
I think he needs to communicate more than give room for assumptions you know.

Chekitaut, kindly do the needful OK. I don't want to agree to the term FRAUD that was labeled against you but once you don't communicate effectively. You give room for name callings and assumptions which the client or engineer is entitled to because you have room for that.

God bless bro

Good day house. Please this is so important. What causes this rising dampness on walls. I have noticed it in many houses in Abuja. What can be done to rectify this problem. it flakes off the cement from the wall. Gives dark patches and swellings on screeded walls. I cannot even use wall papers cause it will soak the paper. I paint the wall after every raining season.
Mind you, the house I am living in now is a new house and german floor waterproof nylon was used to cover the whole floor before concrete was poured. Water proof cement was also used to screed the wall.

Please any solution because it is really embarrassing.
Thank you.

I am interested in the response.

Do you know you can use polystyrene as fill up on a building instead of rubles when there is limitation on space . see some pictures from a bar to be constructed on a roof top of a two storey building and the engineer was trying to reduce weight because he wasn't to sure of the foundation as it is a renovation work.
the pictures explains the rest.

before we get more answers from our engineers in the house, we all know that water will always find is course.
I want to find out what type of foundation does the foundation has is it a raft foundation (casted) or strip foundation (block ), if it is the latter the seepage of water through the blocks will be rapid and if there is a little hole on the damp proof membrane ( Nylon) the water will always make a way through it.

This is what any serious minded builder/engr/developer/client should be doing. This is how i source my granite and sand supplies nowadays.
it is not so much of a big deal like these people make you think. Majority of them are just "middle men" claiming "suppliers".

Imagine someone claiming big time supplier that cannot replace ordinary two trucks delivery pending the resolution of truck issue. and they'll come here be claiming they do this and that. SMH

If you need granite travel to places like ibadan , abeokuta just once and meet with people at the quarry one on one . Dont come here and give money to yahoo boys . They will divert your funds to solve personal problems. They re just greedy and wicked. If you're on this nairaland and your mission is to spoil people's business. You will surely die untimely. I hate people who re not honest with passion . They re cursed people.. they will remain poor until they die. Yahoo boys turn roofers , granite suppliers , building material suppliers. What do you expect from a yahoo boy. I'm sure he is using science to calm all of you he is owing . FSARS ni ma fi ba aye e je..

It is the latter. Funny enough, the inner walls that divide the house into various rooms are not affected. If so, why are the interior walls not affected?
An engineer once told me that the type of soil in a location could cause it. I also noticed that some people actually go to far south to bring in white sharp sand to build in Abuja. I also noticed that very few buildings that do not have this problem have very high foundation. but I have also seen buildings with very high foundation having this problem. its so common in Abuja.

I still need more advice and solution to this problem.

This is termed as Capillary issues or Structural dampness.

This occurs when when a building's damp proof course is faulty or in-existent and allows for water or moisture to rise through the masonry works mostly from the foundation. These days, this issue is forestalled by using a damp proof membrane (A nylon sheet) that is spread meticulously beneath concrete floors.

In other cases (As most likely in yours), where a wrong foundation type is used (Mostly where strip and pad is used instead of raft), these issues occur. Structural dampness happens mostly on the ground floor.

While it can be remedied to a certain degree, the process is a bit cumbersome and can be expensive.

Could you please explain how to remedy the situation? It occurs only at the surrounding walls and not the inner partitioned walls. Thank you...

Sir we don't just use any foundation type on any soil!
If the land is hard enough of maybe around 180KN/mm² do what to say he's to use raft foundation? That's a waste.
Some areas get flooded because they refuse to do their drainage system in passing the water out.
One best thing I know might have happened is this, when they are about casting the oversite concrete commonly called German floor, they might have cover all areas as he said but not have covered the external walls that 225mm 9" portion and this might let the water escape and cause the capillary rise.

According to this statement the external walls might have definitely be uncovered.

There are damp proof creams that can be effectively used. First hack off all paints and plastered levels revealing the masonry works at about 3-6inches above the floor. After this is done, drill holes at about 6 inches interval all across the affected walls and begin to inject the cream into the holes. The cream later spreads and form like a water resistant sheet that prevent future dampness. Afterwards, replaster with "our" not so effective water proof cement and paint. While this has good success rates, it is not 100% effective as some cases are usually more terrible.

You can buy Dryzone Damp Proof Injection Cream on Ebay or Amazon. They are about the best in the market.

water is still going to get into the wall via its foundation blocks, don't you think so?don't 4get this water is coming from the ground and not rain

If you're very sure the DPC was done properly, as only the external walls are affected, the solution is simple. Drain rain water away from your foundation. What I think may have happened, is you have breached your DPC; that is, the final level of your compound is higher than the DPC level. If you've laid interlocking, this may be higher than the DPC. Interlocking, final concreting or back-filling of the compound should be below the German floor. This is a common mistake by majority builders.

If your compound is higher than the DPC, capillary action will result in damp external walls. So drain water away from the outside walls of the foundation by bevelling the compound.

Depending on the kind of activities and volume of traffic expected on it that will determine it's durability.

It has been 7days I paid him N180,000 to deliver 30tons of granite and he hasn’t, telling all sort of lies. Better refund me or you won’t do business on nairaland anymore .

While this can be innovative with the unknown situation of the foundation, I will always discourage such wanton and radical innovation. Such wanton innovation often fail woefully unintended consequences and stress test.

See photos attached.

The first set of photos: Crayford in South East London suburb.

Just like your highlighted project, polystyrene was used to reduce weight and cost in the multi storey carpark. There was a water main burst and the whole carpark was flooded. As you know, polystyrene will float above water, thereby pushing upward the floor of the carpark crushing cars between two floors.

The second set of photos, Taiwan.

The contractor used cooking oil tins to save cost of properly casting columns for a hotel complex. He succeeded until there was a relative minor earthquake and the complex crumbled like a pack of cards.

Be encouraged to design and build structures that will stand the test of time. Cutting corners in the name of innovation often over time reveal what it was: cutting corners.

Amongst many reasons that cause dampness on walls, will like you to note that high proportion of damp problems in buildings are as a result of rain penetration (non dpc related) and capillary action/rising damp (dpc related).

Preferring solutions, I advise physical inspection by an expert (depending on extent of defects), you don't want to create more mess or waste resources while defects persist.

Rain penetration/water seeping from the outer surface; due to drive rain most times(after hours of down pour) you have external walls socked and depending on type of soft sand used for plastering (usually of high salt content) the wall surface absorbs the water, gradually increase in size, travel through the brick and form dampness on the internal surface.
Water proof the surface with bituminous coatings and plaster (mixture of sharp and soft sand) with very good sealant e.g penetron or sikalatex and provide for effective slope to drain off rainwater.
As well, Plaster with coarse and fine sand.

Water rising from ground by capillary action despite having DPC; There is possibility that DPC is faulty or bad installation.
I advise you pave the surface abutting the building to prevent rain water seeping into the wall.
Or if considering interlock paving, make sure the floor has a damp proof course (DPC) which arrests the rising water.

If I haven't been able to mention any likely cause relative to your building, please sort for physical inspection by a water proofing contractor.

70,000 for excavations for a 3 bedroom. Ordinarily, I will consider that outrageous but labour cost is factored by location.

You shouldn't be needing more that 30tons of granite to complete your structure and there are two different rates against granite.

Please provide your best email address for correspondence.

sir, using polystyrene in building is not a new thing and it is used for many things including slabs and whole buildings even in the abroad and nothing is wrong with it.
Polystyrene is not cheap as you are talking about it and there is no cutting corners about it. it is an innovation to reduce building weights just like using hollow pot.
you can read more about polystyrene and its use in construction. polystyrene stands the test of time and natural occurrence is beyond anyone.
