Soil, Concrete and Asphalt Testing

Soil, Concrete and Asphalt Materials Testing

Construction quality depends on materials that perform as designed. GPL provides laboratory and field testing for soils, aggregates, concrete, asphalt, and pavement materials to help clients verify compliance, reduce rework, and make confident construction decisions.

Our testing services support consultants, contractors, developers, and infrastructure owners during design, tendering, construction quality control, and acceptance stages. Testing is performed in accordance with applicable ASTM, BS, EN, AASHTO, and project-specific requirements.

Soil Testing

GPL helps project teams understand soil behavior for earthworks, foundations, roads, and infrastructure platforms.

• Soil classification, grain size distribution, Atterberg limits, and index properties.
• Compaction, moisture-density relationship, field density, and earthworks quality control.
• CBR, bearing-related tests, and strength evaluation for road and pavement design.
• Chemical analysis, sulphates, chlorides, pH, resistivity, and durability-related checks.

Concrete Testing

From fresh concrete checks to hardened strength verification, our concrete testing supports mix control, site acceptance, and structural quality assessment.

• Fresh concrete sampling, slump, temperature, density, and air content checks.
• Compressive strength testing of cubes, cylinders, blocks, and cores.
• Core extraction support and strength evaluation for existing structures.
• Durability-related tests and quality control support for project specifications.

Asphalt and Pavement Materials

GPL supports road and pavement projects with asphalt and pavement material testing that helps verify mix quality, compaction, and field performance.

• Asphalt mix quality control and verification testing.
• Bitumen and aggregate checks for pavement specifications.
• Field density, compaction, and pavement layer acceptance support.
• Material evaluation for roads, parking areas, industrial yards, and infrastructure works.

Aggregates and Stone

• Particle size distribution, shape, density, and water absorption.
• Strength, abrasion resistance, soundness, and durability checks.
• Assessment of deleterious materials and quality indicators affecting concrete and asphalt performance.

Rock Testing

• Point load strength index and unconfined compressive strength.
• Rock density, absorption, durability, and engineering classification support.
