Paver Block Testing - Global Lab

Paver Block Testing
(IS 15658 — Concrete Paving Blocks)

Complete mechanical testing of concrete paving blocks as per IS 15658 — verifying compressive strength, water absorption, abrasion resistance, dimensional tolerances and skid resistance for roads and public spaces.

Overview

What is the Paver Block Testing?

Concrete Paving Blocks (Paver Blocks) are precast concrete units used for pedestrian areas, plazas, driveways, parking areas, ports and industrial floors. IS 15658 specifies minimum compressive strength of 35 N/mm² (Group A, B, C) based on application — with stricter requirements for vehicular and heavy industrial use.

At Global Lab, paver block testing is conducted as per IS 15658 covering compressive strength, water absorption (≤6% by weight), dimensional tolerances (length, width, thickness), flatness, abrasion resistance (for vehicular use) and skid resistance — mandatory tests for CPWD, municipal and NHAI pavement projects.

IS 15658 Group Classification

Group A/B/C compressive strength (≥35 N/mm²) designation assigned.

Compressive Strength

Minimum 35 N/mm² per IS 15658 — tested on full block cross-section.

Water Absorption ≤6%

Low absorption confirms dense, durable concrete mix for paving use.

Abrasion Resistance

Vehicular paver abrasion loss tested per IS 15658 Table 3.

NABL Certified Reports

All results on NABL-accredited letterhead with IS 15658 compliance.

Dimensional Tolerances

Length ±2mm, width ±2mm, thickness ±3mm per IS 15658 Table 1.

3

Water Absorption

3 blocks tested for 24-hour water absorption per IS 15658.
4

Compressive Strength

3 blocks tested in CTM at standard loading rate. Compressive strength per IS 15658.
5

Abrasion & Report

Abrasion resistance tested for vehicular use blocks. IS 15658 Group assigned. NABL report within 28 days.
