In the mid-20th century, civil and geotechnical engineers faced a quiet but critical problem: how to measure the rate at which water could move through soil on-site, without digging it up and bringing it to a lab. Soils behave differently when disturbed. A lab test on a remolded sample might miss the cracks, roots, or layers that actually control water flow in the ground.

ASTM D3385-18 is a standard test method provided by ASTM International (formerly known as the American Society for Testing and Materials). This specific standard is titled "Standard Test Method for Permeability of Porous Concrete." The test method covers the determination of the permeability of porous concrete, which is crucial for evaluating its potential to allow water to pass through, an important characteristic for applications like pavement surfaces, parking lots, and other infrastructure projects where water drainage is a concern.
: Most effective for relatively uniform, fine-grained soils with moderate to low resistance to penetration.
