The “biggest blocks” from our KFN factory can be used to sculpt gardens and landscapes close to nature and attractive. They convert the banks of lakes and rivers or supporting walls into landscape sights. However, our KFN quarry stones and large natural stones, from naturally pure limestone coming from the Elggis mountain in the Swiss canton of Glarus, do not just look good. The unprocessed stone blocks also protect against the erosion of bank areas or slopes. If you need more than 100 metric tons, we need some anticipation.
