Light Weight Deflectometer (LWD) – Efficient Compaction Control
At GEOCIVIL, our Light Weight Deflectometer (LWD) technology provides a fast, non-invasive method for evaluating soil compaction and load-bearing capacity. Whether you’re working on road construction, embankments, or other earthworks, the LWD helps you efficiently manage and control compaction quality, ensuring your project meets the necessary standards for stability and performance.
What is LWD Testing Used For?
LWD testing is used across all types of earthworks to determine critical soil properties. It allows for on-site, real-time measurements of compaction quality, giving you the data you need to make informed decisions during the construction process.
With GEOCIVIL’s LWD testing, you can assess:
- Resilient soil modulus (Evd): Measure the elastic response of soil under loading.
- Degree of compaction: Ensure the ground is compacted to the required specifications for your project.
- Load-bearing capacity: Determine how much load the soil can support without risk of failure.
- Spring stiffness (K): Evaluate the soil’s stiffness to predict how it will behave under loads, critical for pavement and foundation designs.
How LWD Testing Benefits Your Project
By using LWD technology, you can:
- Reduce downtime by getting immediate feedback on compaction quality during construction.
- Avoid costly reworks by ensuring that compaction meets required specifications early in the process.
- Ensure long-term stability of roads, embankments, and other structures by confirming that the soil can support the expected loads.
To learn more about how LWD can benefit your project, please view our brochure for detailed information.
Complementary Services
To provide comprehensive support for your earthworks and construction projects, we offer additional testing services alongside LWD:
- Static Plate Load Tester: Evaluate the bearing capacity and settlement of soils under load.
- Nuclear Densometer Measurement (NDM): Quickly measure soil density and moisture content to ensure proper compaction.
- Dynamic Cone Penetration Test (DCP): Assess the strength and stiffness of soil at various depths.
- Particle Size Distribution: Analyze soil and aggregate gradation to ensure proper material selection.
- Plasticity Index, Hand Auger, and Shear Vane: Additional geotechnical tests to further evaluate soil properties.
