Sand filling (reclaiming water or swampy land with sand before building) is common, but it comes with serious downsides if not done properly. Here are the key disadvantages you should understand clearly:

1. Settlement (Ground Sinking)

Fresh sand fill is loose. Over time, it compresses under the weight of the building.

Leads to cracks in walls and floors

Can cause uneven sinking (differential settlement), which is dangerous


2. Poor Load-Bearing Capacity

If the sand is not properly compacted or stabilized:

The soil may not support heavy structures

Buildings can tilt or fail


3. Water Retention & Flooding

Sand-filled land near water often has:

High water table

Poor drainage planning
Result:

Frequent flooding

Dampness in buildings


4. Erosion Risk

Sand is easily washed away by:

Rain

Flowing water
Without proper retaining structures:

The land can gradually disappear


5. Need for Expensive Soil Improvement

To make it safe, you often need:

Compaction (mechanical)

Piling (deep foundation)

Stone base or laterite stabilization
This increases construction cost significantly


6. Foundation Complexity

You usually cannot use shallow foundations safely.

Requires raft foundation or piling

More engineering expertise needed


7. Environmental Impact

Destroys aquatic ecosystems

Can alter natural water flow

May cause nearby flooding elsewhere


8. Hidden Organic Materials

If the original swamp has:

Peat, clay, or organic matter
These decompose over time:

Causing further sinking even years later


9. Legal / Regulatory Issues

In some areas:

Sand filling water bodies is restricted

Risk of government demolition or penalties


10. Health Risks

Stagnant water around poorly filled land can breed mosquitoes

Increased risk of diseases like malaria



---

Straight advice

Sand filling can work, but only if done professionally:

Proper dredged sand quality

Layer-by-layer compaction

Soil test (very important)

Correct foundation design


If you skip these, you're basically building on a future problem.

Everything you said is accurate, it's either you are an environmental geologist or you copied and pasted everything you wrote from Ai source and you failed to acknowledge the source.

Worse than that is has been happening in Lagos since some criminal elements invaded our peaceful land.

Nteogwuija:
So someone will just go and be filling canal when no be him papa get am?

There has to be some backing somewhere.

ZUBY77:
This is common all over Lekki axis.
The real estate company might be telling the truth. I know a lot of Canals that has been sand-filled IN Chevron axis as well.

.. where will water flow when these canals are blocked... that is why there is a lot of floods in Lagos during raining seasons

Look at the developer critically, you can predict where he comes from.

When that building is pulled down you will begin to hear tribal slur

How do you know who is the developer? cos there's no video or picture of any developer on this said video

This is new month try to shun stup.idity

For little things like this, you still rush go ask AI what to type

Ever8090:
Seriously Nigeria no just get government, to describe wetin we get sef no just make sense .....just give anybody money for office and anything you want them go sign give u....

That's the truth... If you fit make those government officials sign anything, from the lowest level to the highest level.... Just hold money.

ZUBY77:

Then in the future the same government that approve will demolish it

EponObi:
So far as developers like this should be criticized and punished under judicial laws, LASG should get their acts together.

Let's be frank, the LASG is too lax. How did sand filling get to that level and they are not aware of it? If Lagos claim to be a mega city, they should start acting like it.

Their enforcement and surveillance is too loose. It why people like this developer keep getting the balls to do stuffs like this.

It doesn't have to get to demolition stage before the LASG get on top of matters. If this guy in the video didn't blow the whistle, houses will be built on that canal, rented out or sold, then the government will come with the bulldozer. It's embarrassing and shouldn't have to be. Is the LASG saying they don't have total control over their territory?

Some are saying some corrupt officials might have sold permits to the developers. After all the issues and outrage regarding demolition the last years, the LASG hasn't fish out the cabal of officials behind this? By now, I expect they should have put systems in place to curb this.

It's embarrassing to say the least.

How could people be encroaching on a critical infrastructure like the canal and the government isn't aware? How na?

Ever wonder why 20 minutes rain in Lekki and it's surrounding will result to flood? This is the exact reason.

I'll be damn if I say Lagos government isn't aware.

These developers are aware of the dangers and possible future demolition, but they still went ahead to bribe their ways... They rush such buildings and sold them out leaving buyers to bear the loss.

AntiChristian:
What's wrong with sand filling canal if done appropriately with approval from Lagos state?

Na today they've been doing it?

Go island and see massive sand filling!

This one na cruise jare!

Don cry tomorrow when nature comes calling.

Nothing is wrong, but 10 minutes rainfall in Lekki is a disaster to access almost all the streets.

mascot87:
Hope the houses will not be demolished in the future. People no dey ever learn.
And why would any right thinking real estate company cut corners and bribe government officials to sandfill a major canal just to build an estate. If not for anything, this would be a major environmental disaster for that whole area in the future wants flood wants to find it's way through that estate into the Lagoon.

My close friend rented an apartment in one estate at ibeju lekki, my first time coming to see him at his place, as I stepped into the compound, the ground was sinking. I was like " is this where my friend is paying 3.5-4m every year for". Every apartment is so congested.

PHIPEX:
So someone woke up in the morning to do this without any form of approval?

When he succeeds and an innocent man buys the land and build on it, same people like you will twist it and blame same demography you are already implying.

LOL! What a joke. Like you expect the government to be omnipotent and all seeing right? You want LASG to know what is going on at every nook and cranny of the state at every millisecond? Jokers.

If planning permission is not sought and obtained, with the appropriate title validly registered, I will be at the forefront of arguing that the premises be demolished. I will even borrow them my cutlass without given a hoot what anyone says!

talks about tribal slur
When you’re actually the one bringing up a tribal war
Please grow up kid

LegalWolf:
LOL - how the heck would you believe that the government gave approval for this nonsense? Later, if demolition start, a particular demographic may claim being targeted.

The people whose houses get demolished are end-users, ordinary working class people who do not know that a canal was landfilled. And if you stay in Lagos you will know there's no way developer will fill a canal without LASG approval.

AnonPoet:
Man raises alarm after spotting a canal in Sangotedo, Lagos State being sand-filled by a real estate company. He further stated that the developers claimed they had approval from the Lagos State Government to carry out the sand-filling.

I don't see what the news is here. That's how most of VI and Ikoyi was reclaimed.
Also I ounmihht not believe but some parts of Apapa, surulere, Ajao was under underwater before they were reclaimed.
As long as they do it the right way, what it the problem.
They are supposed to lay the water beds with large rocks, then stones before sand comes.

you did not hear him say that they got approval. Tribal slur kọ́, Iranian drone ni.

Ask your Tribu to stop wayo. Na dem go give approval, na same dem go demolish.

Ebuka please concentrate on your region. Nigeria is not a single and homogenous nation state. We are formally and legally and structurally a federation of several homelands. Nothing can obscure or override this critical fact.

Can you build beside an active volcano knowing someday it'll erupt? Or will you filled up volcano and build on it?

If government approved the building then i'd assume its safe to build there.

The context here didn't mention any building yet!

Complete bunkum!

I live in Lagos. I am willing to accept that the occupiers/tenants may not have an idea that this places are canals, but not the 'owners'. Man, this stuff is obvious to the blind. Omo-onile sells nonsense to people and they would not do the required searches, only to find out that the title they have is rubbish.

Every inch of Lagos territory is on the register. All without a single exception. So its strange when I see this argument.

According to Ebuka? Just step out of line and you'll find out there is no such place anywhere in Yorubaland.

I can't believe people are buying land in nigeria(or lagos) do so without checking the land registry? I don't know about already built houses though
