PANDITO Ultra-light Dynamic Cone Penetrometer (DCP) Overview
The PANDITO Ultra-light Dynamic Cone Penetrometer (DCP) from Sol Solution is a simple to use layer by layer compaction control device. It is typically used by the operator, who has just compacted a layer of material, as a self control device to immediately test the compaction quality.
The PANDITO DCP is suited for layers up to a maximum of 50 cm thickness, the typical maximum compaction depth able to be compacted with classical compactors. The results are presented as Cone Resistance (MPa) or California Bearing Ratio (CBR) index. The PANDITO is able to control all types of soils (gravels, crushed, recycled…) up to 50 mm grain size.
This self control test can be done by onsite field staff as the PANDITO DCP is extremely simple to use and interpret. This mean that on-site decisions can be made immediately, rather than waiting for the final test using a normalised technique like the nuclear gauge / densitometer to identify and rectify compaction issues.
Data can be captured and presented using the Excel® based software for results entry, calculation and printing / reports. The results are presented as Number of Blows, Cone Resistance (MPa) or California Bearing Ratio (CBR) index.

Some application examples include establishing:
- whether to keep dirt roads and tracks open (in the rainy season, when its wet or with other difficult conditions), to prevent excessive road damage
and vehicles getting stuck or bogged
- whether to keep un-surfaced runways and taxiways open or not
- whether a trench is backfilled and correctly compacted
