What it involves
A DCP test (Dynamic Cone Penetration) is the fastest, most portable way to assess near-surface soil and pavement strength on site: a 9kg cone dropped 510mm through a guide pipe per AS 1289.6.3.2, producing a blows-per-depth curve that reveals compaction profile and any weak layers. Because it's quick to mobilise and run, it's a common choice for early site investigations, pavement design and construction QA/QC across Melbourne, regional Victoria and the Greater Brisbane area.

Common questions
What is a DCP test used for?
Early site investigations, pavement design, construction quality assurance/quality control, and checking granular soil compaction — it's fast, portable, and gives an immediate read on near-surface strength.
How quickly can I get DCP test results?
Same-day in most cases, from $350 — DCP is our fastest-turnaround test.
Is a DCP test enough on its own, or do I need drilling too?
For shallow, near-surface assessment (pavements, small residential footings, early feasibility) DCP alone is often sufficient. For deeper foundation design we'll typically pair it with drilling and SPT — we'll recommend the right combination for your project.
