At KeralaDeco Contracting, structural safety is our top priority. Every project operates under quality audit parameters established by Nexston Corporations Pvt Ltd.
Concrete & Foundations
- Mix Specification: We use M25 or M30 grade concrete for all major pillars, beams, and foundation slabs.
- Cube Testing: Compression tests are performed on cast cubes at 7 days and 28 days by independent laboratories. Reports are uploaded directly to the client progress portal.
- Reinforcements: Only Fe500D or Fe550D TMT steel bars from certified manufacturers (such as Tata Tiscon or JSW Neosteel) are permitted.
Brickwork & Masonry
- Laterite Stone: Sourced from certified northern Kerala quarries, verified for load-bearing density.
- Solid Blocks: Manufactured under factory-controlled steam curing, with a minimum compressive strength of 7.5 N/mm².
Plastering & Finishes
- Sand Compliance: Double-washed river sand or certified manufacturing sand (M-Sand) is used.
- Curing Protocol: Structural brickwork and concrete plastering are cured for a mandatory 14-day cycle with automated sprinklers to prevent micro-cracks.
