LIGHT WEIGHT Deflectometer

Fast, accurate and easy compaction control!

Light Weight Deflectometers, or LWD, are portable, light weight tools used to determine the load bearing capacity and overall compaction quality of soils, non-cohesive sub-bases and soil improvements in as little as two minutes.

LWDs measure a deflection and provides an estimated modulus value which is based on the force that would be required for that soil type to generate a deflection. This is an important measurement as the actual modulus on site should be compared to the design specification values.

Applications for this non-destructive testing method include road/railway construction, earthworks, quality protection and canal construction, compaction monitoring in pipe trenching and cable ducts or testing of pavement bedding and foundation backfill. The LWD provides a simple, fast and repeatable onsite testing method which increases your quality control efforts and provide cost-saving benefits.

Additional Soil Testing Equipment for Field Applications may be required and Humboldt offers a full line of equipment to meet your needs.

Compaction Density — Our soil density and compaction equipment is typically used to gather soil samples for Proctor testing. Our Nuclear Density Gauges are one of the most accurate methods to determine moisture content in a variety of materials.

California Bearing Ratio (CBR) — The CBR field test set is designed for making CBR determinations in the field, allowing for quick relative strength determinations without having to rely on lab tests.

Augers & Auger Sets — Humboldt offers a variety of augers and accessories in different sizes and for different soil types to aid in getting to deeper testing depths.

Soil Moisture Testers — The soil moisture levels at the time of construction plays a critical role in construction activities. Humboldt’s provide accurate on-the-spot testing capabilities.

Resistivity — These meters provide resistance measurements and are available in 2-, 3-, and 4-electrode applications.
