• Design and drilling of wells
Our experience and database allows us to design and build water-wells almost anywhere in Estonia. Our equipment enables us to drill shallow wells for supplying water for only one household, or deep wells or groups of wells for the water intake of whole cities. We are one of the few firms who are able to drill borewells in locations with a complex geological profile -where aquifers are soft and collapsing, where sand tends to mix with water and where water production is low. These are situations where it is not only necessary to drill a quality borewell, but also to install special screens that are manufactured by our engineers in our workshop. If necessary, we can supply you with screens manufactured by world’s leading specialists GWE Group GmbH (stainless steel or plastic screens and casing pipes).
• Design and drilling of geothermal boreholes
Using the geothermal heat is rising rapidly recent years and these boreholes are included into our service list. We make necessary calculations, prepare the design and drill the boreholes.
• Water pumps, pumping stations, tanks, water supply systems
To ensure that the borewell is not just a pipe protruding out of the ground we offer turnkey projects in external water supply systems. It means that we will install a submersible pump, install a pressure tank and automatic equipment and, if necessary, water purification equipment, install pipelines in the pumping stations and connect the pumping stations to the user. We are importers and distributors of pumps manufactured by SAER Elettropompe S.r.l. offering a full range of products both for pumping drinking water and wastewater. We offer technological renovation of outdated pumping stations as well.
BalRock OÜ has a camera for inspection of borewells enabling to film up to 500 m deep boreholes and give adequate evaluation to the condition of casing pipes and screens of the well.
• Maintenance and repair of borewells
During their lifetime water-wells, like other such facilities, require regular maintenance and, less frequently, repair. Maintenance mostly consists of powerwashing, during which sediments that have built up at the base of the well are washed out. At the same time the inner surfaces of pipes are cleaned. The procedure is completed by determining the new exploitation parameters of the well and taking new water samples. It should be noted that a well requires maintenance when water quality deteriorates, there are traces of sand in the water or the pump run dry.
Borewells must be repaired when the submersible pump or other objects have fallen to its bottom, the casing pipe is rusted and is leaking, or when someone has clogged the borewell. We are always ready to assist our customers in restoring their well to proper condition.
As with most technical installations, wells come to the end of their useful life after decades and must be eliminated. There should be a similar procedure when a borewell has no owner or for other reasons is no longer used. In order to protect the environment, such wells must be eliminated. This is just one of the services that we offer our customers.
• Mast holes and boreholes for earthing contours
We offer all kinds of non-standard drilling services for masts, posts, and holes for earthing, including larger diameters (up to 1,000 mm) and including into bedrock.
