Bore Hole Soakaways

Deep bore soakaways are a very efficient method of dealing with excess surface water and the outflow of a sewage treatment system. TND Drilling provide a full design install and test service for soakaway boreholes of any size. The instillation of soakaways is becoming more popular as the use of soakaway crates / French drain style systems are very restricted by the space available on a site. More info about bore hole soakaways.

Water Well Drilling & Installation

TND drilling have the equipment and expertise to drill water wells to enable water extraction from depths ranging from 5 meters to in excess of 200 meters below ground level. We can offer advice on the expected extraction rates and expected water quality before drilling commences. We work closely with hydrologists who can also advise on all the finer details and liaise with the environment agency if required for a water abstraction licence. An abstraction licence is only required if more than 20,000 litres 4,500 gallons are to be abstracted daily. More Info.

Ground Source Heat Pumps

Installing a ground source heat pump is an intelligent way to reduce heating costs in either domestic, commercial or industrial properties. TND Drilling offer various packages ranging from just the drilling and installation of the ground loop (collectors), all the way through to a turnkey solution for the complete system including the commissioning and handover of the working heat pump.

A typical house would require 1-3 geothermal holes to provide the geothermal energy required. This is dependent on the size of house and its insulation. The hole spacings vary but are typically 10 meters apart and the depth of boreholes is dependent on the geology of the site.

Once the geothermal loops are installed in the borehole the hole is then injected with grout which surrounds the loop. The purpose of the grout is to ensure good surface contact for the transfer of the earth’s heat. The grout also protects the loop and adds stability to the borehole. Each loop is then connected vertically back to the manifold. More info about ground source heat pumps.

Customer Testimonials

We contacted TND as one of three companies to quote on our bore hole and were very reassured by their technical knowledge. And they did exactly what they promised and importantly for us they did not come back with any hidden extra costs.

James, Cambourne Cambridgeshire

We have used TND for years now we have a good working relationship, they are just simple and honest to deal with.

Tim, Colchester

This is the first time we have used TND Drilling once we had sorted a price they came to site, we discussed drilling locations and sorted an install date. As they say the rest is history.

James, Brentwood

We had soakaway issues on a site, so contacted TND Drilling to see their thoughts. We ended up instructing them to do the full soakaway design from that they were able to quote for the soakaway install which they drilled installed and tested for us.

Thank you.

Simon, Kelvedon
