päällyskivi

Päällyskivi is a Finnish term that translates to "paving stone" or "cobblestone." It refers to a type of natural stone or manufactured block used for surfacing roads, paths, and public spaces. Traditionally, päällyskivi were irregularly shaped, hand-laid stones quarried from local sources. These historical examples can still be found in many older European cities and towns, contributing to their distinctive aesthetic and character.

Modern päällyskivi can also refer to precisely cut and shaped stone blocks, often granite or basalt, which offer a more uniform and durable surface. These are frequently used in contemporary urban planning for pedestrian walkways, squares, and driveways. The selection of päällyskivi depends on factors such as durability, aesthetic appeal, cost, and the intended use of the paved area. They are known for their longevity and ability to withstand heavy traffic. In some contexts, the term might also encompass concrete pavers that mimic the appearance of natural stone. The installation of päällyskivi involves careful preparation of the sub-base to ensure stability and drainage, followed by the laying of the stones, often with sand or a similar material used as a joint filler.
