AAC Blocks Nepal — 4, 6 & 8 Inch Sizes
Lightweight, fire-resistant, and earthquake-ready blocks engineered for modern construction across Nepal.
Mechi 4 Inch AAC Block
Manufactured with high-precision technology under **ISO 9001:2015 standards**, Mechi AAC blocks provide the ultimate thermal insulation and seismic safety for Nepal's modern architecture.
Our Manufacturing Process
Following a strict **ISO 9001:2015 certified process**, we transform raw minerals into high-performance building blocks.
Mixing & Slurry
Sand, lime, cement, and water are mixed with an aeration agent to create a precision slurry.
Rising & Pre-Curing
The mixture is poured into molds where it rises like bread, creating millions of tiny air cells for insulation.
Precision Cutting
Once semi-solid, the "cake" is wire-cut into 4", 6", or 8" blocks with millimeter-level accuracy.
Autoclaving
Blocks are steam-cured at 190°C and 12 bars of pressure. This creates the final crystalline structure that ensures zero shrinkage.
Choosing the Right AAC Block Size
Selecting the correct AAC block size is essential for structural performance and cost efficiency. All Mechi AAC blocks share the same 600mm × 200mm face, so the key difference between sizes is thickness — which determines where each block is best used.
4 Inch AAC Block (100mm)
Ideal for internal partition walls and non-load-bearing dividers. Lightweight and easy to install, the 4 inch AAC block is the go-to choice for separating interior spaces in homes, offices, and commercial buildings without adding structural load.
6 Inch AAC Block (150mm)
The standard choice for residential exterior walls and high-rise infill walls. The 6 inch AAC block balances strength, insulation, and weight, making it the most versatile size for everyday construction across Nepal.
8 Inch AAC Block (200mm)
Designed for load-bearing walls, external boundary walls, and maximum thermal insulation. The 8 inch AAC block offers the highest strength and energy efficiency for structural applications and demanding projects.
