Põhjakivi believes in sustainability and follows these principles for the whole production process from quarrying to designing. It all starts with extracting limestone and to do that efficiently and with minimum loss we use electric sawing on each layer separately. It is important to notice natural cracks on the limestone layers and move within these lines to achieve good size on each slate. After sawing we use heavier machinery to lift the slates from the ground one by one and move them to the storage before processing. All this takes experience and knowledge which is given from one generation to another and takes years to achieve.
The limestone slates will be then processed according to each specific order. Each layer has certain qualities which are suitable for different limestone products. Põhjakivi workers know the stone better than their own hands and eliminate all possible cull. But nothing gets waisted, as we have worked out different classes of products with various sizes. This way we use 90-95% of all mined stone. What’s left after that will be used under road construction and in recultivating the quarry once the mining limits have been reached.
