Water boreholes provide a private water supply for domestic drinking or garden/farm supply. Water boreholes work in the same way as the old fashioned well. By drawing water from the natural aquifers in the ground, through bedrock and chalk to provide naturally filtered and cleaner, purer water than that which is piped by water companies.
The supply from a borehole is not affected by hosepipe bans and in the long-term can become a positive selling point for a property when the high cost of water supply in the southwest is considered.
Site investigations are carried out to determine the make-up of the ground preceding the sale of a house or construction projects. They can determine the type of ground or rock on which a property stands or whether there are any voids or faults running through it.
This can help to determine the type of foundations to be used on a build, whether underpinning is required or can even pinpoint the presence of mine workings.
Working with qualified surveyors we drill a series of holes around a site to determine what lies beneath the ground.
The ground maintains a constant heat year round which can be exploited to provide a heat source for your property. Geothermal loops are installed and a mixture of anti-freeze and water is pumped through extracting heat from the surrounding ground.
Where ground instability is an issue piles can be installed for support or underpinning. Steel casing is driven through the unstable ground using a DTH piling hammer until bedrock is reached.
A rock socket is then drilled into the bedrock and reinforcing bar then installed to the bottom of the socket. Concrete or grout is then pumped into the hole to the top. Ground beams are then fixed on top.
Earth and rock anchors are typically made up of steel bars that are installed and grouted into a drilled hole.
The anchors are then put under tension to test them. The rock face is first cleaned down to remove debris.
A series of holes are drilled into good rock and the rock anchor is inserted and grouted into place. Rock mesh is then placed over the anchor ends and bolted into place.
We have a reputable contractor for pump and filtration systems, most of this is on the shelf, ready to cover all your needs.

The main drill for bore holes, piling and geothermal holes is a "Gemsa Gemtrack" compact rig which has been designed for access to small and confined spaces such as doorways, at 0.7 m wide it has been used for piling inside dwellings. It can drill up to 150 m in depth it has a separate hydraulic power pack to run the rig.
We also use hand held drills and frame mounted drills for rock anchors, soil nails and other drilling jobs were the Gemsa would be unsuitable.
We also have various other gear for grouting, rock breaking and ground support.
