Concrete Blocks

Precast blocks used for most modern wall construction in Rwanda, valued for speed and consistency.

Used for

  • External walls
  • Internal partitions
  • Boundary walls

Quality considerations

  • Ask about the block's curing age — blocks used too early can be weaker and more prone to cracking.
  • Check dimensional consistency across a batch; irregular blocks increase mortar use and labour time.

Common mistakes

  • • Buying the cheapest blocks available without checking density or curing quality.
  • • Poor wall bonding and vertical alignment during laying, weakening the finished wall.

Priced per block; varies by size, density and supplier.
