Why 4-inch concrete block — and why ours.
Our 4-inch hollow block is engineered for speed on site: light enough for a single mason to place all day, dense enough to give plaster a solid, dust-free key. Every batch is cast from graded aggregate and Portland-blend cement, vibrated for uniform density, then yard-cured under cover so blocks reach the site strong, square, and ready to lay.
- Consistent 16″ × 8″ × 4″ nominal sizing — minimal shimming
- Sharp arrises and clean webs — better mortar contact
- Cured to design strength before dispatch
- Sourced and produced locally in Georgetown, Guyana
Lightweight partitioning strength.

Vibrated & pressed.
High-frequency vibration on a hydraulic press produces uniform density block to block.
- 02Chapter 02
Graded aggregates.
Washed sand and hard stone are proportioned by weight, not by shovel, for a repeatable mix.
- 03Chapter 03
Controlled cure.
Blocks are cured for 7+ days under cover to reach target strength before they leave the yard.

How to install 4-inch concrete block right.
A short field guide from our yard team. Always follow your engineer's drawings for reinforcement and structural details.
- 1
Lay on a full mortar bed to the levelled foundation course.
- 2
Stagger vertical joints by half a block (running bond) for wall integrity.
- 3
Keep mortar joints at 10 mm — check with a joint gauge every 3rd course.
- 4
Mist blocks lightly in hot, dry weather before laying to slow water loss from the mortar.
- 5
Reinforce openings and long runs with bond beams or vertical rebar as designed.
4-Inch Concrete Block quality standards.
- Manufactured to ASTM C90 hollow load-bearing masonry sizing

What builders order alongside 4-inch concrete block.
A single yard, a single delivery. Here's what typically ships with this product — and why.
Use our load-bearing 6-inch block for external and structural walls, and pair with the 4-inch for interior partitions.
Washed white sand is the fine aggregate for the mortar you'll lay these blocks with.
Red sand backfills the foundation trench and levels the pad before the first course goes down.

4-Inch Concrete Block — frequently asked.
No — 4-inch blocks are rated for partitions and non load-bearing work. For load-bearing walls use our 6-inch block.
About 12.5 blocks per m² of finished wall (roughly 113 per 100 sq ft). Send us your dimensions on WhatsApp and we'll confirm the exact quantity plus mortar.
Wait at least 7 days after laying so mortar joints reach strength and the wall has stopped moving.
