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 (as is common on the Estonian north coast). 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 including USF Johnson, pumpenboese SBF Hagusta and Stüwa (plastic and stainless steel).

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.

Renovation of pumping stations – In connection with Estonia 's accession to the European Union, there are now more stringent regulations in place for public water supply systems both in terms of water quality, as well as equipment and facilities. As a result, local governments and other operators of local water systems have started to renovate outdated pumping stations that no longer comply with the new regulations in terms of construction, equipment, automation and electrical installations, as well as in terms of water treatment. In recent years BalRock LLC has completed dozens of such projects and has extensive experience in renovating pumping stations.

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 fails to produce any water. For carrying out maintenance we have, uniquely in Estonia , a compressor fleet which includes the most powerful Atlas-Copco machines that are capable of producing pressurized air at pressures of up to 21 cubic meters per minute up to 21 bar.
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.

Elimination of borewells – 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.

BLASTING WORK

Blasting work in quarries – Crushing rock by means of blasting has been a special service offered by our team for decades. We operate a Tamrock CHA 680 drilling rig that enables us to drill holes of the required diameter, at the necessary angles, quickly, effectively and with quality. We should emphasise that we guarantee the required disintegration of the rock necessary to ensure problem-free operation of the crushing equipment and other machinery used in quarries. For blasting work we use non-electrical systems that enable us to trigger explosives at different times, ensuring that the rock is sufficiently disintegrated and reducing the unwanted effect of seismic waves on the surrounding environment. Our rich experience and the above-mentioned materials, equipment and methods, combined with our expertise, assure that we have what it takes to crush the various rocks in Estonian quarries. We offer a complete service that includes design work of the blasting as well as obtaining the necessary permits and approvals. Our current clients include Rõstla and Otissaare quarries in Jõgevamaa and Harku quarry in Harjumaa also Reinu quarrie in Raplamaa and Võhmuta quarrie in Lääne-Virumaa.

Preparing a route for infrastructure systems – Even hard bedrock on the planned path of a pipeline or a road, it is no obstacle for us. Our experience allows us to prepare the ground in the necessary site and, if necessary, in the very proximity of the facility and carry out the explosion while ensuring that all structures remain sound, and protecting local people from noise. The best example of our work is involvement in Estonia 's largest-ever infrastructure blasting project – Laagna road that was cut into the limestone of Lasnamäe.

Demolition of structures, dredging of seabed by blasting – Our team is always ready to carry out various specialised blasting projects. They are enthusiastic professionals and every project is approached with care and preparation. By now, our team has completed a number of challenging projects which include several projects that can be called masterworks. The most spectacular are demolition of ice on the Pirita river to free the river during winter, demolition of empty concrete buildings in the town of Paldiski, demolition of the water tower of the former Tallinn Shiprepair Company on the corner of Mere boulevard and Sadama street , and dredging work in the Tallinn Passenger Port and Heltermaa Port.

We look forward to your order
