GPR Ballast Evaluation Surveys

Need a GPR Ballast Evaluation Survey?

When it comes to determining the quality of a rail-track and its load capacity, a GPR Ballast Evaluation Survey (BES) is absolutely essential.

A railway ballast survey, using the latest GPR technology, analyzes the properties and thickness of the ballast layer quickly and with little to no service disruption. This analysis of the ballast layer provides vital insight to the quality of the substructure and detects changes in material properties, which ensures the track design and performance is optimized for years to come.

Using a dual frequency system — the GSSI GPR control unit with central frequencies of 300MHz and 800MHz — UDS Civils is able to deliver high resolution, detailed results with a greater depth than single frequency systems. Our team utilizes a tested approach to surveying that gathers data at significantly lower cost and time, allowing your business to maintain continuity.

The detailed analysis of the railway combined with penetration depths of up to 3m under favorable conditions provides our clients with comprehensive data and information that can be used in countless projects and applications in the future.

Rather than deploying survey crews trackside, disrupting service and increasing costs to the company, a GPR Ballast Evaluation Survey can quickly and easily analyze track conditions — including the impact of fine-grained materials that retain more moisture and affect performance in the long-term.

Investing in non-disruptive, efficient, and valuable analysis of your rail-track is the best way to prevent future safety or service costs. When working with UDS Civils to complete a GPR Ballast Evaluation Survey, quality of analysis and accuracy of data are our top priorities.
