FAQ
The main difference is: Shape of a hole - 4-hole bricks have four evenly arranged circular holes, creating a unique and beautiful texture when exposed. They are ideal for Loft-style decoration, garden paving, or as ventilation bricks, a look that 2-hole and 3-hole bricks cannot achieve.
Yes, that's fine. The method is to orient the circular holes outwards. Air will flow through the four holes while maintaining the wall structure. This is suitable for fences, balconies, storage rooms, or bathroom walls that need ventilation.
Construct using standard mortar and bricklaying, laying the bricks with the wide face outwards (exposing the four circular holes). After completion, clean the brick surface. You may apply Brick Sealer to protect against moisture and give a glossy finish, or leave it in its natural state for a raw, cool look.
Place on a soil/sand base. The four circular holes allow for good drainage, preventing waterlogging. You can allow grass or moss to grow in the holes for a more natural look, or pour a thin layer of cement to make it more stable.
