Sisäpurku

Sisäpurku is a Finnish term referring to the process of demolishing or dismantling a building or structure from the inside out. This method is often employed when the exterior of the building needs to remain intact, perhaps due to historical preservation requirements, structural integrity concerns for surrounding properties, or when the building is situated in a densely populated area.

The interior demolition process typically involves carefully removing materials and components layer by layer, starting from the highest floors and working downwards. This systematic approach helps to control dust, debris, and potential structural collapse. Specialized equipment and techniques are often used to ensure safety and efficiency.

Sisäpurku can be more time-consuming and labor-intensive than traditional demolition, which often involves rapid collapse. However, its advantages lie in its precision and reduced impact on the external environment. It allows for the selective removal of materials, which can be beneficial for recycling and salvage operations.

Common applications for sisäpurku include the renovation of historic buildings, the removal of asbestos or other hazardous materials from interior spaces, and the deconstruction of structures within active facilities where a controlled demolition is necessary. The planning and execution of sisäpurku require careful assessment of the building's structure and the surrounding environment.
