GEOTECHNICAL DRILLING & GROUND INVESTIGATION 

Danbar’s geotechnical drilling and ground investigation services are unrivalled thanks to our 30 years of experience in environmental, geotechnical drilling.

ENVIROMENTAL & GEOTECHNICAL DRILLING

Geotechnical drilling and environmental drilling and engineering solutions come in various different forms depending on the particular project you’d like to achieve.

Environmental and geotechnical drilling allows us to sample different soils to determine the different types of earth on a site prior to any construction activity taking place.

Here at Danbar Drilling, we’ve completed countless ground investigation projects in various types of developments including petrol stations, factories, foundries, treatment works and landfills: to name few.

Our wide range of drilling capabilities help clients to fulfill all of their drilling requirements quickly, efficiently and effectively.

Through the art of geotechnical drilling and the art of rotary equipment, we’re able to use various techniques to recover samples and undertake in-situ testing.

Each of our employees are highly skilled, fully trained operatives who’re able to work in areas with limited access as our Beretta T44 can fit through spaces only 1 meter wide. (See Equipment section).

Rotary drilling techniques are employed on ground investigation where boreholes are required into very dense gravel or bedrock.

Samples of the bedrock are recovered in seamless plastic tubes for subsequent logging by a suitably qualified engineer for lab testing.

ROTARY OPEN HOLE DRILLING

Here at Danbar Drilling, our ground investigation services also include a technique called rotary open hole drilling.

Open hole drilling is a technique we use to form deep observation boreholes to gain samples of rock which couldn’t be recovered from cable percussive drilling or window sampling.

This geotechnical drilling technique uses what we call a power rotary cutting head on the end of a shaft which rotates as it drills into the ground.

Completed boreholes may have an installation ranging from a basic groundwater monitoring pipe through to more sensitive instrumentation such as a vibrating piezometer.

    ENVIROMENTAL SITE INVESTIGATIONS

    Intrusive environmental site investigation needs to utilise various techniques in rotary drilling.

    It can be a very sensitive area to work within and a lot of clients need to drill without fluid.

    As it can often create unnecessary mess while increasing the risk of contamination.

    The technology we’ve invested inhere at Danbar Drilling is ideal for environmental site ground investigations.

    Our Sonic drilling rig is one of only 6 in Europe at the moment and it is especially suited to investigating heavy metal, organic and other types of contamination including land fill debris.

    It is also the fastest drilling method on earth for environmental site investigations.

    With this piece of fine machinery will can drill without flush and take continuous core samples, making it faster and cleaner than conventional rotary drilling.

    We will install standpipes for monitoring groundwater or soil gases.
