GEOTHERMAL DRILLING ENGINEERS
Here at Danbar Drilling, we specialise in the delivery of geothermal drilling for all kinds of sites across the UK.
our professional team have been drilling and installing range of vertical ground systems for many years.
Thanks to our experience, we have dealt with practically every kind of geological formation imaginable, meaning that we can deliver a quick and problem-free service to suit your needs.
Using the latest in industry-leading equipment (including one of only six sonic drills available in Europe).
We can make sure that your project is completed on-time and on-budget.
We have the knowledge, versatility and unbeatable drilling rigs to ensure that your vertical ground structures and systems can be installed in the shortest possible time.
DANBAR’S GEOTHERMAL DRILLING SERVICES
Our team will visit your site before any major drilling work has to take place. Our director or lead driller will evaluate the entire site, including access points and the availability of a steady water supply in the area.
It is important, before we begin, that the surface material undergoes a British Geological survey to assess its suitability.
If the site’s access points are large enough for our rigs to get to where they need to be, and the surface material is geologically suitable, then our team will start as soon as possible.
The boreholes that we can create can be drilled to various depths.
It is largely dependent on the consistency and quality of the ground strata.
The depths and distances between the boreholes will be decided by both the clients and engineers during the initial planning phase.
Our state of the art geothermal drilling fleet consists of rigs which are capable of drilling boreholes of more than 100 meters.
Our consistent investments in the latest geothermal drilling technology allows us to provide all of our clients with the cleanest, fastest and most effective drilling service available in the UK today. Our rigs enable us to drill with air, air mist, mud or water flushes depending on the condition of the site.
Utilising our sonic technology, however, we are able to drill without the use of mud if the project requires it. We also offer a range of modular machines which are perfect for use in the sites where access is limited to our larger rigs.
GEOTHERMAL LOOP INSTALLATION
Once the boreholes have been drilled to the required depths, our team will then install the geothermal loops. We can install 32mm or 40mm geothermal loops using our hydraulically powered loop winders. The thermal grout that we provide is them mixed by our drillers in our own hydraulic or air powered mixers. This ensures that the grout is mixed to a correct consistency, preventing issues later on.
The borehole itself is then grouted from the base upwards using a pump and tremie method. This will lift out any debris or water with it. The grout then seals the drift and fill deposits. This means that the borehole itself is sealed and resistant to potential contamination. The thermal grout also acts as an effective conductor between the heat of the earth and the fluid in the pipework.
In addition, before any of our geothermal loops are installed, they are subjected to a pressure test. We use both air and hydro-static pressure tests to check all of our loops. Once these loops have passed the test, we supply certificates as evidence of their reliability.
Before we leave the borehole, we make sure that the loop itself is cut down to ground level. Plastic soil popes are inserted into the ground and backfilled with pea gravel to ensure the loop is protected prior to its connection with the complete geothermal system.
