HOW TO KNOW IF YOUR BLOCK SUPPLIER IS GIVING YOU SUBSTANDARD BLOCKS
Let’s be honest, not all block suppliers have your best interest at heart.
Many people pay for "9-inch" or "6-inch" blocks, only to get low quality, poorly cured blocks that start cracking even before they’re used on site.
The painful part?
You may not notice the damage until months after construction… when your walls start showing hairline cracks or sounding hollow.
Here’s how to protect yourself:
1. Do the "Drop Test"
Pick one block and drop it from waist height.
A solid block will fall with a thud and stay intact.
A weak block will break, crumble, or sound hollow. That’s a red flag.
2. Check the Edges and Surface
Are the edges sharp and straight?
Is the surface smooth and compact?
If the blocks look “ashy,” powdery, or have broken corners, they’re likely low cement content or not well cured.
3. Ask About the Mix Ratio
A serious supplier will proudly tell you:
“1 bag of cement per 30–35 blocks.”
If they say 50–60 per bag, run.
4. Request for Curing Time
Blocks should be cured for at least 7 days before delivery.
Fresh, uncured blocks might look good now, but they’ll become brittle later.
Why This Matters:
Your entire structure depends on the quality of your blocks. Don’t build your dream on weak materials.
Pay attention. Inspect thoroughly. And if in doubt, buy from trusted suppliers or let professionals handle it.
