Quality you can read off the docket
ISO 9001:2015 certified quality management, mixes designed and tested to IS codes, and an in-house laboratory that checks raw materials and every delivery.
A
Press a cube
Every delivery is sampled. Cubes are cured and crushed at 7 and 28 days and the result is read against the specified grade.

PASS
A demonstration of how a 28-day cube result is read against the specified strength under IS 456. Results shown are illustrative; project records are issued per pour.
Controls
Automated batching, manual vigilance
- Computerised batchingEvery ingredient weighed on load cells against the approved mix design, with batch records kept.
- Raw material testingAggregate grading and moisture, cement and water checked in-house before use.
- Fresh concrete testsSlump and temperature at the plant and at site, before the pour starts.
- Cube testingCubes cast per sampling plan, cured and crushed at 7 and 28 days; results reported to the client.
- Delivery documentationEach load leaves with a docket: grade, quantity, batch time and the truck.

Slump classes we batch to
Slump is measured with the standard cone at the plant and again at site. Bands follow IS 456.
| Class | Slump | Typical use |
|---|---|---|
| Low | 25-75 mm | Mass concrete, lightly reinforced sections, pavements |
| Medium | 50-100 mm | Normally reinforced slabs, beams, walls, columns |
| High | 100-150 mm | Pumped concrete, congested reinforcement |
| Flowing | flow test | Self-compacting concrete, placed without vibration |
