  • No cracks and chips.
  • Blocks should not have an overly porous texture.
  • Blocks should be in 15 centimeters (or 6 inches) wide minimum.
  • Blocks should be grey in color.

Before buying hollow blocks you need, you can test the strength of the hollow blocks by dropping them from shoulder height.

Test five blocks at a time. If two or more break, it means they're not strongly made hollow blocks. Find hollow blocks elsewhere.
