In-House Laboratory
Batch-Wise Quality Testing
We crush our own bricks daily so that they never fail on your site. Here are the core tests every batch must pass before dispatch.
Compressive Strength Testing (CTM)
Each batch is rigorously tested on our digital Compression Testing Machine to ensure it meets the 7.5 to 12.5 MPa benchmarks.
Water Absorption Analysis
Bricks undergo a 24-hour submersion test. We mandate a strict < 12% water absorption rate, outperforming the IS limit of 15%.
Efflorescence (Salinity) Test
Bricks are placed in shallow water dishes for multiple days to verify zero salt leaching, ensuring paint longevity.
Dimensional Tolerance Check
Physical checks confirm exact ±1mm dimensional accuracy so contractors can save up to 25% on mortar joints and plaster.
Compliance
Bureau of Indian Standards Matrix
We strictly conform to the national engineering codes mandated for government and commercial infrastructure.
