Do you know the meaning of that third symbol in your designs?
You guys should at least try to look up some of these things.
No be every long rope be necklace!

Yeah
Some one told me about it
Said it looks like a nazi logo
I had to look it up to confirm
E be like sey I go stop to post this design
Thank you

On choice of plaster sand.

Bricklayers have told me some sand have more gum than others hence they advocate for the ones with gum for plastering. It appears price vary for each type as well from suppliers.

There's also the notion about white and not so white plaster sand.

My question border around what disadvantage is there with using sand without enough gum and can cement which is a bonding agent resolve whatever bonding issue the gum was meant to take care of.
Can this also results in cracks on the wall(which were not present prior to plastering).

I'll appreciate contributions from the members. Thank you

Am not qualified to answer, but since none has responded, let me try my best.

Basically plaster sand is just choice between sand, clay/silt, or a varying mixture of both.

The pure sand gives a harsh texture, which should normally require wall screeding before paint is applied. It also requireds plenty cement and or bonding agent. But the sand does not shrink or expand, hence it doesn't result in any cracks.

The pure clay/silt gives a smooth finish as if the wall hath already been screeded. Requires little or no cement / bonding agent. But clay swells when moist and shrinks when dry resulting in ugly mud cracks.

Basically they use a varying mix of both to achieve the positives of both worlds.

The mixing can be done on site by the artisans or naturally in the river where the sand was dredged. The further upstream of the river, and the more coarse sand aggregates, while the further down the river, the more finer and more clay content

The gum is his way of understanding clay's sticky properties. Recall they don't use cement in clay pots, bricks and tiles but just clay stickiness is enough

Hope this helps.

It would be nice to know why you want to know about ground/ foundation beams, who suggested it and why.

Anyways, ground beams simply put are beams placed on the ground. They are part of foundation. They are used when the bearing capacity of the soil is low and where the structure is susceptible to settlement.

The essence is to prevent uneven settlement when it occurs cos the structure has been" tied together " by the ground beam.

Thanks for the explanation
Actually I saw "ground beam optional" on the quotation an engineer gave. So I was wondering why it should be optional if the foundation was to be done right.

What would be the work of a foundation beam

Have a small plot or looking to effectively plan and manage your plot

Here’s what we did on a plot slightly less than half plot

Land size = 27 x 100ft

Design: 4 bedrooms bungalow all en-suite and cross ventilated.

Greetings all..
Please what's the condition to use a ground beam on a foundation. And is ground beam and foundation beam the same .

Thanks all

Just to add to what Engr Aforxy said

Ground beams are laid on ground just like raft (but they are not raft) they are used where the soil bearing capacity is low, they help prevent differential settlement (sinking foundation) especially when constructing a strip foundation (p.s All foundation work should follow structural engineer/drawing recommendation)

Plint beam on the other hand is provided not at the natural ground level but after some number of blocks, it is mostly used in cases when you have high foundation walls, it reduces your wall and column slenderness and prevent column buckling (Shearing) because of its height.
It also tie all columns together and make them monolithic
As a result of high foundation, lots of filling is expected in and outside of the foundation, hence the plinth beam provides another layer of support against the soil load acting on both side of the wall, in order to avoid foundation tearing.

Check out one we did on this thread

Does the foundation beam help to solve dampness experience on the building walls .

You can ask your engineer why the ground beam is optional.
However, the best foundation option for your building would be determined by your structural engineer after carefully studying the result /recommendation of your sub soil investigations.

Do you have the structural drawings for the building. If yes, what type of foundation was designed. Build accordingly to the structural drawings and if you don't have any, get one done.

I think central bank volt door couldn't be stronger than that sir.

Is this right or wrong??

Are pipes or cables

I noticed the heights of the foundation (walls) are not at the same level. How can I correct it pls

Thank you

Ask the engineer on site why? If the land is sloppy sometimes it's usually like that

thanku, I appreciate
The engineer said it will take shape once we continue with the work.... Land is not sloppy, engineer didn't give any good reason why it is so.

Your German floor or plinth beam (aka foundation chaining) will correct it.

I want put a round ground beam, don't know if it will correct it.

Sorry to say this, ur engineer is a quack Engineer! What is the work of setting out before digging? Or what is the work of a plum and line rope bn used to align walls, well am not an engineer but from my own little knowledge I have, from foundation to the lintel, all walls must level irrespective of the land shape. Pls do a critical correction now to avoid issues. I think the plint beam will help a lot but if it's an upstairs, pls let the Experts engineer here advise U.

You are correct with the comments. Setting out, take proper ground level during digging

No, that's due to poor craftsmanship or supervision work.

Use German floor/Oversite Concrete to correct it, it's an error that could have been avoided.

BIGGIE121:

This is a serious after thought.
Note: Cables are passed underground in buildings but such would have been adequately designed and constructed.
This one was done even after the German floor, there will be numerous voids when this floor is eventually finished, it may not manifest immediately.

Nice

We r on d same page, it's still the engineer/supervisor fault. U must u know the capabilities of ur artisan nd u must force them to use line nd plum at all level to avoid issues like this

This can be corrected by either cutting or adding to the height of the walls in order to bring them to the same level.

Take level of the highest point on the foundation walls and transfer this point across the walls.

Get your bricklayer to either make up to the correct level with mortar / blocks or carefully cut down the blocks to the required height.

You can also correct it when casting the oversite concrete if the difference isn't much.

I doing a little job in Warri now so if you need me to come around we can make plan before going back to Benin cause I now stay in Benin for some reason and if you need me in Lagos trust me you got me too

You can do better by constructing chamber covers so the Chambers don't disfigure your jobs

Hi all, I need something like the below done. The measurement is 600 by 2.5mm. How much will it cost?

Casement window with burglary and net
600 x 1.5---50k

Without burglary
600 x 1.5---45k

This your advice is extensive and empirical.
