Structural Rebar Protection

Concrete cover blocks maintain exact reinforcement spacing as mandated by IS 456:2000. Unlike plastic spacers that cause micro-cracking and thermal separation, our concrete cover blocks share identical thermal expansion and bonding properties with surrounding structural concrete, preventing moisture ingress and reinforcement corrosion.

Key Technical Features & Engineering Benefits
Conforms to IS 456 & BS 7973, High point-load crushing capacity (> 50 MPa), Available in 20mm, 25mm, 40mm, 50mm, 75mm
Recommended Civil & Structural Engineering Applications
Bridge piers, Structural columns, Foundation rafts, Post-tensioned beams, Coastal seawalls

Packaging Configurations

500 pcs & 1,000 pcs heavy woven sacks

  • Bagged Cargo: Shrink-wrapped, palletized and covered with waterproof tarpaulins during transit.
  • Bulk Cargo: Transported via dedicated pressure pneumatic bulkers (25 - 35 MT capacity) for zero spillage and direct silo discharge.
  • Traceability: Each bag and consignment marked with Batch Number, Date of Manufacture, and Net Weight.
Storage & Shelf Life Recommendations
  • Store in dry, covered warehouse sheds elevated on wooden pallets off the concrete ground.
  • Prevent direct contact with moisture, high humidity, and open rainwater to avoid pre-hydration or compaction.
  • Shelf Life: Typically 12 to 24 months from manufacturing date when stored in original un-opened moisture-proof packaging.
  • Safety & PPE: Use protective dust masks, safety goggles, and work gloves during batching and mechanical handling.
