Dynamic cone penetration testing (DCPT)

We provide dynamic cone penetration testing (DCPT) as part of our comprehensive ground investigation services. This fast, cost-effective method is ideal for assessing soil strength and compaction, particularly in pavement design and shallow foundation assessments.

What is dynamic cone penetration testing?

DCPT involves driving a steel cone into the ground using a standard weight dropped from a fixed height. By measuring the number of blows required to drive the cone a set distance, we can evaluate soil strength, density, and uniformity across different layers.

This method is particularly useful for:

  • Pavement and road base evaluations
  • Shallow foundation investigations
  • Soil compaction assessments
  • Identifying changes in subsurface conditions

DCPT provides continuous strength data with depth, making it valuable for identifying soft spots, variations in ground conditions, and assessing subgrade performance.

Efficient, in-situ soil testing

Our field teams use portable, hand-operated or mechanical DCPT rigs, allowing for testing even in restricted-access sites. The test is quick to perform, requires minimal ground disturbance, and results can be interpreted on-site or analysed further for design and reporting.

We offer:

  • In-situ testing up to depths of 3–5 metres (depending on ground conditions)
  • Blow count data recorded at regular intervals
  • Correlation with California Bearing Ratio (CBR) values, if required
  • Integration with other site investigation methods

Why choose Vision Survey?

  • Fast, reliable testing carried out by experienced operatives
  • Ideal for road, highway, and small development projects
  • Accurate data to support design and construction decisions
  • Fully compliant with safety and technical standards
  • Trusted by engineers, developers, and contractors across the UK

DCPT is a simple but powerful tool for identifying potential ground issues early, helping you reduce risk and build with confidence.
