Field Density Test (FDT)

In construction, the stability of your project is only as good as the ground it stands on. We provide comprehensive Field Density Testing (FDT) in the Philippines to ensure your soil compaction meets rigorous industry standards and project specifications. Inch-On Materials Testing Laboratory strictly adheres to ASTM and AASHTO standards to guarantee a stable foundation and long-term safety for every structure.

Core Testing Services

The Field Density Test is a crucial quality control measure used to determine the in-place density and moisture content of compacted soils. We utilize industry-standard methods to verify that your site is ready for the next phase of construction.

1. In-Situ Density Methods

The most common and reliable field method for determining the density of soil in place.

A precise alternative for measuring the volume of the test hole to calculate soil density.

For rapid, real-time results on moisture and density without extensive physical sampling.

2. The Foundation of Accuracy: Proctor Test

We assess the resistance of aggregates to weathering, specifically their ability to withstand repeated freezing and thawing or wetting and drying cycles.

3. Strength & Stability Verification

Measuring soil strength at its best condition to ensure it can support heavy loads.

Ensuring the material used for structural fill is fit for purpose.

Why Our Testing Matters

Using uncompacted or sub-standard soil can lead to structural settlement, pavement cracks, and costly rework. Our reports provide the clarity and consistency needed by contractors, developers, and civil engineers across the Philippines to:

As a DPWH-BRS Accredited laboratory, we ensure your project meets all national regulatory standards.

Proper compaction today prevents the sinking and shifting of foundations tomorrow.

Ensure the ground can safely support roads, buildings, and foundation piles.

Follow the proven workflow: Proctor → FDT → CBR for quality you can trust.
