1. CEMENT CONCRETE FLOORING – SCOPE
1.1 Scope Of Work

Laying of cement concrete flooring for residential, industrial, and roof applications. Includes all finishes: plain cement finish, red oxide, floor hardener, anti‑dust, sponge finish, power trowel finish, and tile‑base preparation.

1.2 Reference Drawing

Architectural floor finish schedules, structural slab drawings, industrial flooring layout.

🎨 TYPES OF FINISHES (with method)
Plain cement finish

Wood float / steel trowel after laying; common in residential.

Sponge finish

Lightly dab with wet sponge after initial set; non‑slip texture.

Power trowel finish

Machine‑floated for industrial floors; very smooth, high density.

Floor hardener / dry shake

Apply hardener powder on fresh concrete, trowel in; for warehouses.

Red oxide / colour finish

Mix pigment (red oxide) with cement 1:2, apply 25‑40 mm, polish.

Anti‑dust / sealant coat

Liquid sealer applied on cured floor; for warehouses, basements.

Industrial floors often receive a combination: power trowel finish + hardener + curing compound.

5. FLOORING LAYING PROCEDURE
5.1 Subgrade / Base preparation
  • Compact subgrade (if on earth) or clean existing slab. Apply bonding slurry.
5.2 Laying & levelling
  • Fix screed strips, pour concrete, compact with roller/vibrator, level with straight edge.
5.3 Finishing (as per type)
  • Perform chosen finish while concrete is green (sponge, trowel, hardener, etc.).
5.4 Curing & Joints
  • Keep moist for 7–14 days. Cut contraction joints in industrial floors.
⏱️ LABOUR OUTPUT (per 8 hours)
ActivityMason + 2 helpersRemarks
Residential flooring (40‑50mm)20–30 m²includes finishing
Industrial flooring (100‑150mm)15–25 m²machine assisted
Red oxide / colour finish12–18 m²polishing extra
Roof flooring (with slope)18–25 m²drainage detailing

Output varies with thickness, reinforcement, and finish complexity.

🏭 SPECIAL FLOORING – ROOF & INDUSTRIAL
Roof / terrace flooring
  • Minimum thickness 40mm with slope 1:100 to drains.
  • Mix M15 with waterproofing compound (2% by weight of cement).
  • Expansion joints at 3m grid.
Industrial flooring
  • Grade M20 to M30, thickness 100‑200mm with reinforcement mesh.
  • Floor hardener application @ 3‑5 kg/m².
  • Contraction joints every 4‑6m, sawn after curing.
