1. PAVER BLOCK – SCOPE OF WORK
1.1 Scope Of Work

Laying of interlocking concrete paver blocks for road paving, footpaths, pedestrian plazas, and heavy-duty industrial roads/container yards. Includes sub-base preparation, laying of bedding sand, block installation, edge restraints, joint filling, compaction, and quality control.

1.2 Reference Standards

IS 15658 (Precast concrete blocks for paving), IRC:SP:63 (Guidelines for use of interlocking concrete block pavement), ASTM C936 (interlocking concrete pavers).

🧱 PAVER TYPES & RECOMMENDED THICKNESS
Application / Traffic ClassPaver TypeThickness (mm)Compressive Strength (MPa)
Footpath / PedestrianRectangular / Zigzag50 – 6030 – 35
Residential roads / Light trafficInterlocking (I-shape, Dumbbell)60 – 8035 – 40
Commercial streets / ParkingHeavy-duty interlocking80 – 10040 – 45
Heavy duty / Industrial roadsHeavy-duty (reinforced)100 – 12045 – 50
Container yards / PortsExtra heavy-duty (with fiber)120 – 150≥50

As per IS 15658, minimum grade M35 for light traffic, M40 for heavy traffic.

📦 MATERIAL CONSUMPTION (per 10m² paved area)
MaterialFootpath / LightHeavy DutyUnit
Paver blocks44–48 pieces (for 60mm thick, 200x100mm)40–45 pieces (for 100mm thick, 200x100mm)nos. (approx)
Bedding sand (30–50mm)0.35 – 0.450.45 – 0.55m³
Joint filling sand (fine)15 – 2020 – 25kg
Edge restraint concrete (if cast)0.15 – 0.200.25 – 0.35m³ per 10m length
Base course (WMM/GSB) – 250mm2.5 – 3.03.5 – 4.0m³

Paver count varies with shape and pattern (herringbone uses more cuts). Add 5% wastage.

🔲 LAYING PATTERNS & EDGE RESTRAINTS
Common patterns
  • Herringbone (45° / 90°): Best for load distribution – used in heavy duty and roads.
  • Stretcher bond: Aesthetic for footpaths.
  • Basket weave: Decorative plazas.
  • Circular / radial: Custom designs.
Edge restraints
  • Concrete kerb (M20) cast in situ or precast.
  • Steel / concrete edging pinned into base.
  • Essential to prevent horizontal creep of blocks.
6. PAVER LAYING PROCEDURE
6.1 Subgrade & Sub-base Preparation
  • Excavate to required level, compact subgrade (98% proctor).
  • Lay GSB/WMM in layers, compact to 98% density.
6.2 Bedding Sand Spreading
  • Spread coarse sand (30–50 mm) using screed pipes; level to correct profile.
  • Do not compact before paver laying.
6.3 Paver Installation
  • Lay pavers in chosen pattern, starting from edge restraint.
  • Cut blocks at edges using masonry saw.
  • Maintain joint width 2–5 mm.
6.4 Compaction & Joint Filling
  • Use plate compactor with rubber mat (80–100 Hz) – minimum 3 passes.
  • Spread fine sand over surface, vibrate into joints, repeat until joints full.
6.5 Final Rolling & Inspection
  • Final compaction check, surface tolerance ±5 mm with 3m straight edge.
  • Sweep excess sand, open to traffic after 24 hours.
⏱️ LABOUR & MACHINERY OUTPUT
ActivityOutput (per 8h)Team / Equipment
Sub-base laying & compaction60–80 m²Grader + roller + 4 labour
Bedding sand spreading100–150 m²3 labour + screed
Paver laying (simple pattern)25–40 m²2 masons + 2 helpers
Paver laying (herringbone)15–25 m²more cutting
Compaction & joint sanding150–200 m²plate compactor + 2 labour

Output depends on block size, pattern complexity, and site access.

🏭 HEAVY DUTY ROADS / INDUSTRIAL PAVING
Design & material
  • Paver thickness ≥100 mm, grade M40–M50.
  • Base course thickness ≥300 mm (cement-treated base optional).
  • Use edge restraints with concrete curb M30, dowelled if required.
  • Joint width 3–5 mm; joint sand with bitumen coating for dust control.
Compaction & quality
  • Heavy plate compactor (≥100 Hz) with high amplitude.
  • Check flatness after compaction – max deviation 5 mm.
  • Proof load test for industrial yards.
