Avoid This Common Infiltration Testing Pitfall

Even experienced field crews can encounter trouble when double-ring infiltrometers aren’t inserted correctly. If the rings go in unevenly or disturb the soil around them, water can escape along the edges. The result? Infiltration rates that look better than they are.

That’s where IGS rings stand out.

IGS double-ring infiltrometers feature sharp, beveled edges on both the inner and outer rings—angled in opposing directions. This design helps the rings cut cleanly into the soil, reducing disturbance and forming a tighter seal. The result is a level setup and more accurate infiltration data.

Small detail. Big difference.
