Interlocking Paver Blocks: Thickness, Grade and the Base Beneath

Use 60 mm pavers for footpaths and sit-outs, 80 mm for car driveways and 100 mm or more where lorries turn, made to IS 15658. A 1,000 sq ft area takes about 4,650 rectangular 200 × 100 mm pavers plus wastage. The base matters as much: compacted GSB or WMM, then 20–40 mm of bedding.

Pavers & kerb stones

How we supply it: Paver blocks are arranged through a partner block maker who quotes, supplies and bills them and pays us a referral commission. The base is ours: GSB, WMM, crusher dust and 6 mm chips come from our crusher by the tipper load, so the sub-base can be laid and compacted before the pavers arrive.

StandardIS 15658

In one line: A paver block is a precast concrete unit, made to IS 15658, laid dry on a sand bed so that its joints interlock and spread wheel loads across the neighbouring blocks.

How interlocking pavers carry a load

A paver block is a precast concrete unit, made to IS 15658, laid dry on a sand bed so that its joints interlock and spread wheel loads across the neighbouring blocks.

Interlock needs three things: tightly butted blocks, sand packed into the joints and a firm edge such as a kerb. Lose the edge and the blocks creep apart.

Next question: Which thickness for my driveway? More

Thickness and grade by traffic (IS 15658)

For a house driveway used by cars, 80 mm is the safe pick. If our 18 MT tipper will ever unload on the drive, treat it as medium traffic: 80–100 mm on a WMM base.

Rectangular blocks in a 45° herringbone give the best interlock for car driveways; I-shape suits larger parking areas. Keep square and grass pavers for foot traffic.

The base: where our materials go

Base thicknesses above are typical for house work. Heavy-use yards need a proper pavement design.

  1. Dig to firm soil and compact the subgrade.
  2. Lay and compact GSB, typically 100–150 mm for cars and 150–200 mm where lorries go, with a WMM layer on top for heavy use.
  3. Fix kerbs or an edge beam before laying a single paver.
  4. Spread 20–40 mm of bedding (crusher dust or coarse sand) and screed it level without compacting.
  5. Lay the pavers, cut the edges, then vibrate them into the bed with a plate compactor.
  6. Brush fine dust into the joints and vibrate again.

Next question: How much GSB and dust for my area? More

Quantities for 1,000 sq ft

Typical estimate: for rectangular 200 × 100 mm pavers (50 per m²), using our bulk densities.

  • Pavers: about 4,650 blocks, 4,880 with 5% wastage
  • Bedding at 30 mm: about 2.8 m³, roughly 4.7 MT of crusher dust
  • GSB at 150 mm compacted: about 14 m³, roughly 28–30 MT, close to two 18 MT tipper loads

Next question: What does GSB cost delivered to my area? More

Paver delivery checks

  1. Measure ten random blocks; thickness and size must be uniform or the surface will step.
  2. Ask for the lot's compressive-strength results to IS 15658 and the grade.
  3. Look at edges and corners: chipped arrises become trip lines after laying.
  4. For coloured pavers, check shade across pallets and plan to mix pallets while laying.
  5. Count by pallet and record broken pieces before signing.

Next question: How do I edge the driveway? More

Stacking and staging

  • Unload pallets by hand or forklift; tipping chips the edges.
  • Stack near the laying face on level ground.
  • Keep the bedding dust covered so rain does not soak it unevenly.
  • Draw from several pallets at once to blend colour.

Next question: Where should rainwater from the paved area go? More

Why driveways sink and rock

  • Laying on loose fill with no compacted GSB; ruts show up in the first monsoon.
  • No kerb or edge beam.
  • Bedding pavers in cement mortar, which cracks and traps water instead of flexing.
  • 60 mm blocks where tankers or lorries turn.
  • No fall for drainage; aim for about 1 in 40 to 1 in 50 away from the house.

Questions buyers ask

Paver Blocks: questions buyers ask

How thick should a driveway paver be?

For a house driveway used by cars, 80 mm. IS 15658 lists 60–80 mm for light traffic, but 60 mm leaves no margin if a water tanker or material lorry ever uses the drive. Where heavy vehicles turn, use 100 mm on a WMM base.

Can you drive on 30mm pavers?

Not safely. Units that thin are decorative tiles for foot traffic; under a car wheel they rock and crack. IS 15658 starts at 50–60 mm even for non-traffic areas and 60–80 mm for light vehicles.

Is 20mm thick enough for a paver?

No. 20 mm units are tiles laid on mortar over a slab, not interlocking pavers. Anywhere a vehicle might cross needs at least 60 mm, and a driveway needs 80 mm.

How much does a 1000 square foot paver block cost?

Our Today's rates page shows an indicative Chennai market rate per sq ft for 60 and 80 mm pavers; the partner confirms the day's rate. What we can tell you: 1,000 sq ft takes about 4,880 rectangular blocks with wastage, about 4.7 MT of crusher dust for bedding and nearly two tipper loads of GSB, and we quote the dust and GSB delivered to your area.

Which pattern is strongest for a driveway?

Herringbone at 45° to the direction of travel, with rectangular blocks. It locks blocks both ways and resists the creep that turning wheels cause; stretcher bond is weaker under vehicles.
