Rotary Percussive/Core Drilling

We can supply in house geotechnical consultants to analyse all site investigation data and prepare factual and interpretive reports.

Denver Drilling Services offer vast experience and a wide range of drilling rigs to suit the majority of investigation applications. One of our rotary percussive techniques specialises in the investigation of old mine workings, mine shaft entries, old culverts and is ideal for drilling in all types of rock strata. 

All drilling rigs also carry strings of overburden steel casing which enables continuous drilling through difficult sands and gravels strata until sold rock has been pentrated. 

When required, all our rigs can be adapted to undertake diamond rock coring. Steel core barrels with diamond heads are used to take rock samples at required depths for analysis. Plastic tube liners are used to case the samples for testing analysis.
