Builders and professionals. Small 3 bedroom flat that I want to build. See the quotation that was given to me. Are the prices okay? Though, I will have to now explore other builders. I have been dealing solely with this particular guy because, he helped me in acquiring the land.

bixton:


It will be better if you can post the pix of this small 3 bedroom flat to enable anyone to comment and effectively critic the quotation given to you. Also the site location/state(city/township/village) will help as to various rates.
Thanks.

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 sot common in Abuja.
I still need more advice and solution to this problem.
Plastered wall can also cause dampneas on the wall. If the soil around the wall on the lower part is very loose your plaster sand can get soaked and the dampness can rise up. Secondly, we often build our Chambers too closed to our build wall, this is wrong and can also cause dampneas since water flows thru the Chambers regularly and part of our building wall is used for the Chambers then you will often see the wall around that chamber dampened.

Solution: Apply 15-20mm tick layer of Gravitex painting above the height of the dampness you have noticed. This is the simplest and fastest solution. Other solution are cumbersome.

beamNIGERIA:


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.

diordaves:


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.

olayinka1234:
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.

But you can't just apply protective paint if no effort is made to keep water away from the walls. The Gravitex over time will react with water and the problem will not go away. The solution is to keep water away from the foundation whatever method. Water and foundations are not good friends.

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.

It has being taking to Granite delivery. i lost d sand to IKate Suppliers so never worry you get d delivery as promised.

Chekitaut:
Good evening all, [s]i was informed of several post from a friend here about Segzy post[/s]. Yes i hv never d9 u paid me oof service wish is yet to be delivered. is a pity d urgly incident occurred anyway. We left Abeokuta with 2trucks of 30tons load going to Eng Samuel's site @Oko afon. we access tru Oshodi, because Atan terrible state of road, we encounter a gridlock at Toyota to Cele which made a experted nite delivery a day time delivery. Most of d truck like nite due to VIO, FRSC & LASMAN in lagos to aviod fall victims to law.
The 2trucks where not mine i lease it. D driver was not my staff, but they fall in d hands of FRSC corp each ticket was charge almost 90keach.no speed limit, no driver license, no fire..., no xtra tyres etc. what i dod waa to inform him. is a big challenge 2tricks. i hv disappointed no doubt but is never my making.
i was out of cash i told u on call that even N1k i dont hv thinking to deliver & get bal. Anyway i know Segzy14 very well, what you did is not of u, but...no wahala. Tell me what u want you said i shld refund. the running cost of d delivery is above N340k. i will refund if u insist, i will deliver if u want, wish ever way.

gbadexy:

The solution proffered may be possible even though it seemingly defy logic to just cover up the place with waterproof materials.
Unlike tiles and undercoat that totally seals off the surface, graffitex would still allow water vapor to escape since the binder is emulsion based.
what may happen is controlled gradual escape of the ground water.
Like you rightly stated sir, the best option is not to have the water there to cause other damages.

I installed wooden internal doors and the doors were made over two years now with absolutely no problems. The doors remain straight, well laped with no warping.

I used IKPAYA wood. This is what we call it in Delta. It may be different in your area. It is also called Azobe, Ekki or red ironwood. The wood is sometimes used for electric pole and bridges as it's water resistant. The biological name is Lophira alata.

The trick is to source for dried ones and after making the doors, don't hang immediately. Stand them to dry further. I allowed mine to stand and dry further for 30 days before hanging and vanishing. Also mind the door thickness which is 40mm.

How much does this internal wooden doors cost?

So:
Frame
Skirting

Lock
Vanishing

You are very correct
Type of wood and the finishing determined the durability.

I did this for a nairalander going to 2yrs and no defects on it till now
